ˆ Features

Your RadioShack 1000-Channel Handheld Trunking

Scanner is one of a new generation of scanners de-

signed to track Motorola Type I, Type II, hybrid _®analog

systems, (such as S_®martnet and Privacy Plus ) plus

GE/Ericsson EDACS . Those systems are extensively

used in many 800 MHz, 900 MHz, and UHF communica-

tion systems.

Trunking communications systems let a large group of 2-

way radio users (or even different groups of 2-way radio

users) efficiently use a set of frequencies. Instead of se-

lecting a specific frequency for a transmission, the user

simply selects a talk group. The trunking system auto-

matically transmits the call on the first available frequen-

cy, and also sends (on a different frequency called a

data channel) a code that uniquely identifies that trans-

mission.

Since the trunking system might send a call and its re-

sponse on different frequencies, it is difficult to listen to

trunked communications using a regular scanner. The

scanner lets you select and monitor the data channel fre-

quency sent with a 2-way radio transmission, so you can

hear the call and response for that user and more easily

“follow” the conversation.

The scanner also lets you scan conventional transmis-

sions, and it is preprogrammed with service banks for

convenience. By pressing a single button, you can

quickly search those frequencies most commonly used

by public service and other agencies, without tedious

and complicated programming.

This scanner gives you direct access to over 37,000 ex-

citing frequencies, including police and fire departments,

ambulance services, and amateur radio services, and

you can change your selection at any time.

Your scanner also has these special features:

Triple-Conversion Circuitry — virtually eliminates any

interference from IF (intermediate frequency) images, so

you hear only the selected frequency.

Features

20 Channel-Storage Banks — you can store up to 50

channels in each of 10 different banks, in two separate

groups, for a total of 1000 channels, so you can more

easily identify calls.

Five Scan Lists — you can store up to 50 trunking talk

group IDs in each trunk scanning bank.

Digital Weather Alert — uses the digital SAME (specific

area message encoding) signal transmitted with weather

alerts to identify the type of alert being issued.

Note: This scanner does not use the specific area fea-

ture of SAME. It responds to all alerts received.

Two-Second Scan Delay — delays scanning for about

2 seconds before moving to another channel, so you can

hear more replies that are made on the same channel.

Lock-Out Function — lets you set your scanner to skip

over specified channels or frequencies when scanning

or searching, and skip over talk group IDs when tracking

trunked systems.

Priority Channels — lets you program one channel in

each bank (20 in all) and then have the scanner check

that channel every 2 seconds while it scans the bank, so

you do not miss transmissions on those channels.

Five Service Banks — frequencies are preset in sepa-

rate police (fire/emergency), aircraft, ham, marine, and

weather banks, to make it easy to locate specific types of

calls.

Auto Backlight — automatically turns on the backlight

when the scanner receives signals.

Simultaneous Trunking Operation — allows the scan-

ner to trunk two trunking systems, Motorola and EDACS,

at the same time, as well as conventional systems.

Hypersearch — lets you set the scanner to search at

up to 300 steps per second in frequency bands with 5

kHz steps, compared to the normal search speed of 100

steps per second.

Features

Hyperscan — the scanner automatically scans up to

50 channels per second to help you quickly find interest-

ing broadcasts.

Key Lock — lets you lock the scanner’s keys to help

prevent accidental changes to the scanner’s program-

ming.

Data Signal Skip — lets you set the scanner to skip

non-modulated or data signals (such as fax or modem

transmissions) during searches. This lets the scanner

avoid non-voice signals, making a search faster.

Disconnect Tone Detect — the scanner automatically

tunes to the trunking data channel when it receives a

disconnect transmission. You can turn this off, so you

can continuously monitor a channel with a weak trans-

mission where conversations are often disconnected.

Manual Access — lets you directly access any channel.

Liquid-Crystal Display — makes it easy to view and

change programming information.

Display Backlight — makes the scanner easy to read in

low-light situations.

Flexible Antenna with BNC Connector — provides ad-

equate reception in strong signal areas and is designed

to help prevent antenna breakage. Or, you can connect

an external antenna for better reception.

Monitor Memories — let you temporarily store up to 10

frequencies or talk group IDs.

Memory Backup — keeps the frequencies stored in

memory for an extended time if the scanner loses power.

Three Power Options — let you power the scanner us-

ing internal batteries, external AC power using an option-

al AC adapter/charger, or DC power using an optional

DC cigarette-lighter power cable.

Key Confirmation Tones — the scanner sounds a tone

when you perform an operation correctly, and an error

tone if you make an error.

Features

Battery Save — saves battery power when the scanner

does not detect any transmissions for more than 5 sec-

onds when a channel is manually selected.

Battery Low Alert — warns you when battery power

gets low.

Weather Alert Indicator — your scanner also functions

as a severe weather alert monitor.

FCC NOTICE

Your scanner might cause radio or TV interference even

when it is operating properly. To determine whether your

scanner is causing the interference, turn off your scan-

ner. If the interference goes away, your scanner is caus-

ing it. Try the following methods to eliminate the

interference:

• move your scanner away from the receiver

• connect your scanner to an outlet that is on a differ-

ent electrical circuit from the receiver

Features

• contact your local RadioShack store for help

Note: Mobile use of this scanner is unlawful or requires

a permit in some areas. Check the laws in your area.

SCANNING LEGALLY

Your scanner covers frequencies used by many different

groups including police and fire departments, ambulance

services, government agencies, private companies, am-

ateur radio services, military operations, pager services,

and wireline (telephone and telegraph) service provid-

ers. It is legal to listen to almost every transmission your

scanner can receive. However, there are some transmis-

sions you should never intentionally listen to. These in-

clude:

• telephone conversations (cellular, cordless, or other

private means of telephone signal transmission)

• pager transmissions

• any scrambled or encrypted transmissions

According to the Electronic Communications Privacy Act

(ECPA), as amended, you are subject to fines and possi-

ble imprisonment for intentionally listening to, using, or

divulging the contents of such a transmission unless you

have the consent of a party to the communication (un-

less such activity is otherwise illegal).

This scanner is designed to prevent reception of illegal

transmissions, in compliance with the law which requires

that scanners be manufactured in such a way as to not

be easily modifiable to pick up those transmissions. Do

not open your scanner’s case to make any modifications

that could allow it to pick up transmissions that it is not

legal to listen to. Doing so could subject you to legal pen-

alties.

We encourage responsible, legal scanner use.

Features

ˆ Preparation

You can power your scanner from any of three sources:

• internal batteries (not supplied)

• standard AC power (using an optional AC adapter)

• vehicle battery power (using an optional DC

adapter)

USING INTERNAL BATTERIES

You can power your scanner using four alkaline, lithium,

or rechargeable (Ni-Cd or Ni-MH) AA batteries (not sup-

plied). For the best performance and longest life, we rec-

ommend RadioShack batteries.

Using Non-Rechargeable Batteries

Follow these steps to install non-rechargeable batteries.

1. Turn VOLUME/OFF counterclockwise until it clicks to

make sure the power is turned off.

2. Slide up and hold the tab on the back of the scan-

ner, then pull up the battery compartment cover

from the top edge.

Preparation

3. Before you install alkaline or any other non-

rechargeable batteries, use a pointed object such

as a ballpoint pen to set ALKALINE

JACK

NI-

CD inside the compartment to ALKALINE.

Warning: Set ALKALINE

JACK

NI-CD to NI-CD

for use only with nickel cadmium (Ni-Cd) or nickel

metal hydride (Ni-MH) rechargeable batteries.

Never attempt to recharge non-rechargeable batter-

ies. Non-rechargeable batteries can get hot or

explode if you try to recharge them.

4. Install two batteries in the compartment and two in

the cover as indicated by the polarity symbols (+

and –) marked inside those locations.

Cautions:

• Use only fresh batteries of the required size and

recommended type.

• Always remove old or weak batteries. Batteries

can leak chemicals that destroy electronic cir-

cuits.

• Do not mix old and new batteries, different types

of batteries (standard, alkaline, or rechargeable),

or rechargeable batteries of different capacities.

Preparation

5. Replace the cover, inserting the lower tabs first.

When BATT.Loflashes and the scanner beeps every

15 seconds, replace all four batteries.

Warning: Always dispose of old batteries promptly and

properly. Do not bury or burn them.

Using Rechargeable Batteries

You can also use four rechargeable batteries. Before

you use Ni-Cd or Ni-MH batteries, you must charge

them.

The scanner has a built-in circuit that lets you recharge

Ni-Cd and Ni-MH batteries while they are in the scanner.

To charge the batteries, set ALKALINE

JACK

NI-CD

to NI-CD, install the batteries in the scanner, and connect

an external AC or DC adapter to the scanner’s POWER

jack (see “Using AC Power” on Page 13 or “Using Vehi-

cle Battery Power” on Page 14).

Warning: Do not connect either adapter to the scanner if

non-rechargeable batteries (such as alkaline batteries)

are installed in the scanner and ALKALINE JACK NI-

CD is set to NI-CD, or if you are unsure of the switch’s po-

sition. Non-rechargeable batteries will get hot and can

even explode if you try to recharge them.

Before you use Ni-Cd or Ni-MH batteries for the first

time, charge them at least 24 hours to bring them to a

full charge.

Discharged batteries take about 10 to 18 hours to fully

recharge. If you use the scanner while the batteries are

charging, charging takes longer.

Notes:

• Ni-Cd batteries last longer and deliver more power if

you occasionally let them fully discharge. To do this,

simply use the scanner until it beeps every 15 sec-

onds and BATT.Loflashes.

• To prevent damage to Ni-Cd batteries, never charge

them in an area where the temperature is above

113°F (40°C) or below 40°F (4°C).

Preparation

Important: This scanner can use Ni-Cd

rechargeable batteries. At the end of a

Ni-Cd battery’s useful life, it must be re-

cycled or disposed of properly. Contact

your local, county, or state hazardous

waste management authorities for infor-

mation on recycling or disposal pro-

grams in your area or call 1-800-843-7422. Some

options that might be available are: municipal curbside

collection, drop-off boxes at retailers such as your local

RadioShack store, recycling collection centers, and mail-

back programs.

USING AC POWER

You can power the scanner using an 9V, 300 mA AC

adapter and a size H Adaptaplug^™adapter (neither sup-

plied). Both are available at your local RadioShack store.

Cautions:

You must use a Class 2 power source that

supplies 9V DC and delivers at least 300

mA. Its center tip must be set to negative

and its plug must fit the scanner’s POWER 9V 300MA

jack. Using an adapter that does not meet these

specifications could damage the scanner or the

adapter.

• Always connect the AC adapter to the scanner

before you connect it to AC power. When you finish,

disconnect the adapter from AC power before you

disconnect it from the scanner.

Follow these steps to use the scanner on AC power.

1. Turn VOLUME/OFF counterclockwise until it clicks to

make sure the power is turned off.

2. Insert the Adaptaplug into the AC adapter’s cord so

it reads TIP –. Insert the Adaptaplug into the scan-

ner’s POWER 9V 300MA jack.

3. Plug the AC adapter into a standard AC outlet.

If rechargeable batteries are installed and ALKALINE

JACK

NI-CD is set to NI-CD, the adapter powers the

Preparation

scanner and recharges the installed batteries at the

same time.

USING VEHICLE BATTERY POWER

You can power the scanner from a vehicle’s 12V power

source (such as cigarette-lighter socket) using a 9V, 300

mA DC adapter and a size H Adaptaplug (neither sup-

plied). Both are available at your local RadioShack store.

Cautions:

You must use a power source that sup-

plies 9V DC and delivers at least 300 mA.

Its center tip must be set to negative and

its plug must fit the scanner’s POWER 9V 300MA

jack. Using an adapter that does not meet these

specifications could damage the scanner or the

adapter.

• Always connect the DC adapter to the scanner

before you connect it to the power source. When

you finish, disconnect the adapter from the power

source before you disconnect it from the scanner.

• If batteries are installed, make sure the battery

switch inside the battery compartment is set to the

correct position (see “Using Internal Batteries” on

Page 10).

1. Turn VOLUME/OFF counterclockwise until it clicks to

make sure the power is turned off.

2. If the adapter has a voltage switch, set the switch to

9V.

3. Insert the Adaptaplug into the DC adapter’s cord so

it reads TIP –. Insert the Adaptaplug into the scan-

ner’s POWER 9V 300MA jack.

4. Plug the other end of the adapter into your vehicle’s

cigarette-lighter socket.

If rechargeable batteries are installed and ALKALINE

JACK

NI-CD is set to NI-CD, the adapter powers the

scanner and recharges the installed batteries at the

same time.

Preparation

Note: If the scanner does not operate properly when

you use a DC adapter, unplug the adapter from the

cigarette-lighter socket and clean the socket to remove

ashes and debris.

CONNECTING THE ANTENNA

To attach the supplied

flexible antenna to the

connector on the top of

your scanner, align the

slots around the anten-

na’s connector with the

tabs on the scanner’s

BNC connector. Then

slide the antenna’s con-

nector down over the

scanner’s connector and

rotate the antenna con-

nector’s outer ring clockwise until it locks into place.

Connecting an Optional Antenna

The scanner’s BNC connector makes it easy to connect

a variety of optional antennas, including an external mo-

bile antenna or outdoor base station antenna. Your local

RadioShack store sells a wide selection of antennas.

Note: Always use 50-ohm, RG-58, or RG-8, coaxial ca-

ble to connect an outdoor antenna. If the antenna is over

50 feet from the scanner, use RG-8 low-loss dielectric

coaxial cable. If your antenna’s cable does not have a

BNC connector, your local RadioShack store carries a

variety of BNC adapters.

CONNECTING AN EARPHONE/

HEADPHONE

For private listening, you can plug an optional earphone

or mono headphones into the

jack on top of your

Preparation

scanner. This automatically disconnects the internal

speaker.

Listening Safely

To protect your hearing, follow these guidelines when

you use an earphone or headphones.

• Do not listen at extremely high volume levels.

Extended high-volume listening can lead to perma-

nent hearing loss.

• Set the volume to the lowest setting before you

begin listening. After you begin listening, adjust the

volume to a comfortable level.

• Once you set the volume, do not increase it. Over

time, your ears adapt to the volume level, so a vol-

ume level that does not cause discomfort might still

damage your hearing.

Traffic Safety

Do not use an earphone or headphones with your scan-

ner when operating a motor vehicle in or near traffic. Do-

ing so can create a traffic hazard and could be illegal in

some areas.

If you use an earphone or headphones with your scan-

ner, be very careful. Do not listen to a continuous broad-

cast. Even though some earphones/headphones let you

hear some outside sounds when listening at normal vol-

ume levels, they still can present a traffic hazard.

Preparation

CONNECTING AN EXTENSION

SPEAKER

In a noisy area, an optional extension speaker, posi-

tioned in the right place, might provide more comfort-

able listening. Plug the speaker cable’s / -inch (3.5-

mm) mini-plug into your scanner’s jack. Your local Ra-

dioShack store carries a selection of suitable speakers.

ATTACHING THE BELT CLIP

To make your scanner easi-

er to carry when you are on

the go, use the supplied

belt clip. Use a Phillips

screwdriver and the sup-

plied screws to attach the

clip to the scanner.

Preparation

ˆ About Your Scanner

We use a few simple terms in this manual to explain the

features of the scanner. Familiarize yourself with these

terms and the scanner’s features, and you can put the

scanner to work for you right away. Simply determine the

type of communications you want to receive, then set the

scanner to scan those communications.

The scanner scans conventional frequencies and trunk-

ed systems. For more information about trunked trans-

missions see “Trunking Operation” on Page 38.

A frequency, expressed in kHz or MHz, is the tuning lo-

cation of a station. To find active frequencies, you use

the search function or refer to a frequency reference

such as the included Trunking Frequency Guide.

Besides searching within a selected frequency range,

you can also search your scanner’s service banks. Ser-

vice banks are preset groups of frequencies categorized

by the type of services that use those frequencies. For

example, many amateur radio frequencies are located in

the HAM service bank.

When you search and find a desired frequency, you can

store it into a programmable memory location called a

channel. Channels are grouped into channel-storage

banks. The scanner has 500 channels in channel-

storage bank A and another 500 in channel-storage

bank B. Each bank of 500 is divided into ten 50-channel

sets. You can scan the channel-storage banks to see if

there is activity on the frequencies stored there.

Or, when you find a frequency, you can store it into a

temporary memory location called a monitor memory

until you decide whether or not to move it to a channel.

Just keep in mind — you search frequencies and scan

channels.

UNDERSTANDING BANKS

Service Banks

The scanner is preprogrammed with all the frequencies

allocated to the weather, ham, marine, aircraft, and po-

lice (fire/emergency) services. This helps you quickly

find active frequencies instead of doing a limit search

(see “Service Bank Search” on Page 27).

Channel Storage Banks

To make it easier to identify and select the channels you

want to listen to, all the channels are divided into main

bank Groups A and B. Each main bank group has 10

banks of 50 channels. Use each channel-storage bank

to group frequencies, such as those for the police de-

partment, fire department, ambulance services, or air-

craft (see “Guide to the Action Bands” on Page 59).

For example, the police department might use four fre-

quencies in your town while the fire department uses an

additional four. You could program the four police fre-

quencies starting with Channel 1 (the first channel in

bank 1), and program the fire department frequencies

starting with Channel 51 (the first channel in bank 2).

About Your Scanner

Monitor Memories

The scanner also has 10 temporary memory locations

called monitor memories. Use these monitor memories

to temporarily store frequencies when you search

through an entire band (see “Searching For and Tempo-

rarily Storing Active Frequencies” on Page 25). You can

then move a frequency to a channel for permanent stor-

age. See “Moving a Frequency From a Monitor Memory

to a Channel” on Page 29.

While you are searching frequencies, the 10 numbers at

the top of the display indicate the 10 monitor memories.

MONappears and the flashing number beside it indicates

the currently active monitor memory.

STORING KNOWN FREQUENCIES

INTO CHANNELS

You can locate and store specific frequencies into chan-

nels for later use. To assist you in locating a desired fre-

quency from the scanner’s wide range, consider using a

frequency guide. Good references for active frequencies

are the RadioShack Police Call Guide including Fire and

Emergency Services, and Official Aeronautical Frequen-

cy Directory. We update these directories every year, so

be sure to get a current copy.

Note: To store trunked system frequencies, see “Storing

Trunked Frequencies” on Page 40.

Follow these steps to store frequencies into channels.

• If you entered an invalid frequency in Step 2,

Error appears and the scanner beeps three

times. Enter a valid frequency.

• The scanner automatically rounds the entered

number to the nearest valid frequency. For exam-

ple, if you enter 151.473 (MHz), your scanner

accepts it as 151.475.

Press DELAY to pause scanning 2 seconds after the

end of a transmission before scanning proceeds to

the next channel (see “Delay” on Page 31). The

scanner stores this setting in the channel.

you did not press HOLD (A/B), simply press 8 or 9 to

continue searching.

Note: Because there are many different frequencies al-

located to fire and police departments, it can take sever-

al minutes to search all the service frequencies.

Search Skip Memory

You can skip up to 50 specified frequencies during a limit

or direct search and up to 20 specified frequencies dur-

ing a service bank search. This lets you avoid unwanted

frequencies or those already stored in a channel.

Note: You cannot skip frequencies during WX service

search.

To skip a frequency, press S/S (L-OUT) when the scanner

stops on the frequency during a limit, direct, or service

search. The scanner stores the frequency in memory

and automatically resumes the search.

• If you selected all frequencies to be skipped within

the search range, the scanner beeps 3 times and

does not search.

• If you select more than 50 frequencies to skip, each

new frequency replaces a frequency previously

stored, beginning with the first stored frequency.

• Press 8 or 9 to select a skipped frequency while

HOLD appears. L/O appears when you select a

skipped frequency.

LISTENING TO THE MONITOR

MEMORIES

2. Enter the number of the desired target channel

where you want to move the frequency that is stored

in the monitor memory, then press PROG. PGM

appears.

3. Press MON/CLR (•) then enter the number (0–9) of

the monitor memory containing the frequency.

4. Press E. The frequency transfers from the monitor

memory into the selected channel.

Operation

5. Repeat Steps 2–4 to store the remaining monitor

memory frequencies into channels, as necessary.

SCANNING THE STORED CHANNELS

To begin scanning channels, press SCAN. The scanner

scans through all non-locked channels in the activated

banks. (See “Locking Out Channels” on Page 32 and

“Turning Channel-Storage Banks On and Off” on

Page 31). When the scanner finds a transmission, it

stops on it. When the transmission ends, the scanner re-

sumes scanning.

Notes:

• If you have not stored frequencies into any chan-

nels, the scanner does not scan.

• If the scanner picks up unwanted partial, or very

weak transmissions, turn SQUELCH clockwise to

decrease the scanner’s sensitivity to these signals.

To listen to a weak or distant station, turn SQUELCH

counterclockwise.

• To ensure proper scanning, adjust SQUELCH until

the audio mutes.

• To scan in the trunk scanning mode, see “Trunking

Operation” on Page 38.

MANUALLY SELECTING A CHANNEL

You can continuously monitor a single channel without

scanning. This is useful if you hear an emergency broad-

cast on a channel and do not want to miss any details —

even though there might be periods of silence — or if

you want to monitor a specific channel.

To manually select a channel, press MAN, enter the

channel number then press MAN again.

Or, during scanning, if the radio stops at a channel you

want to listen to, press MAN one time. (Repeatedly

pressing MAN at this time causes the scanner to step

through the channels.) Press SCAN to resume automatic

scanning.

Operation

ˆ Special Features

DELAY

Sometimes a user might pause before replying to a

transmission. To avoid missing a reply on a specific

channel, you can program a 2-second delay into any

channel or frequency. The scanner continues to monitor

the channel frequency for an additional 2 seconds after

the transmission stops before resuming scanning or

searching.

Depending on how the scanner is operating, follow one

of these steps to program a delay.

• If the scanner is scanning and stops on an active

channel where you want to store a delay, quickly

press DELAY before it continues scanning again.

DLYappears.

• If the desired channel is not selected, manually

select the channel, then press DELAY. DLYappears.

• If the scanner is searching, press DELAY while the

scanner is searching. DLYappears and the scan-

ner automatically adds a 2-second delay to every

frequency it stops on in that band.

To turn off the 2-second delay, press DELAY while the

scanner is monitoring a channel, scanning, or searching.

DLYdisappears.

TURNING CHANNEL-STORAGE

BANKS ON AND OFF

You can turn each channel-storage bank on and off.

When you turn off a bank, the scanner does not scan

any of the 50 channels in that bank.

While scanning, press the number key that corresponds

to the bank you want to turn on or off. Numbers appear

at the top of the display, showing the currently selected

banks.

Special Features

The scanner scans all the channels within the displayed

banks that are not locked out (see “Locking Out Chan-

nels”). The bank number flashes when the scanner

scans a channel that belongs to the bank.

Notes:

• You can manually select any channel within a bank,

even if that bank is turned off.

• You cannot turn off all banks. One bank must

always be active.

LOCKING OUT CHANNELS

You can increase the scanning speed by locking out

channels that have a continuous transmission, such as a

weather channel. To lock out a channel, manually se-

lect the channel, then press L-OUT(S/S). L/O ap-

pears.

Note: You can still manually select locked-out channels.

To remove the lockout from a channel, manually select

the channel, then press L-OUT(S/S). L/Odisappears.

To unlock all channels in the banks that are turned on,

press MAN to stop scanning, then hold down L-OUT(S/S)

until the scanner beeps twice.

PRIORITY

The priority feature lets you scan through the channels

and still not miss important or interesting calls on specific

channels. You can program one stored channel in each

bank as a priority channel (10 for the banks in Group A

and 10 for the banks in Group B). If the priority feature is

turned on, as the scanner scans the bank, it checks that

bank’s priority channel for activity every 2 seconds.

The scanner automatically designates each bank’s first

channel as its priority channel. Follow these steps to se-

lect a different channel in a bank as the priority channel.

1. Press PROG.

Special Features

2. Enter the channel number you want to select as the

priority channel, then press PRIORITY (H/S). P

appears to the right of the selected channel number.

3. Repeat Steps 1 and 2 for the channel in each bank

you want to program as a priority channel.

To review all priority channels (in ascending order only),

press PROG, then repeatedly press PRIORITY to see the

numbers of the priority channels.

To turn on the priority feature, press PRIORITY during

scanning. PRI appears. Then the scanner checks the

designated priority channel every 2 seconds in each

bank. The bank number appears at the top of the dis-

play.

To turn off the priority feature, press PRIORITY. PRIdis-

appears.

Notes:

• The priority feature must be turned off to listen to the

monitor memories or to use the data skip feature.

• If you have locked out all priority channels,

LOCOUt appears when you activate the priority

feature. To unlock any desired priority channels, see

“Locking Out Channels” on Page 32.

USING THE KEYLOCK

To protect the scanner from accidental program chang-

es, turn on the keylock feature. When the scanner is

locked, the only controls that operate are SCAN, MAN,

KEYLOCK, VOLUME/OFF, and SQUELCH.

To turn on the keylock, hold down KEYLOCK until K/L

appears. To turn it off, hold down KEYLOCK until K/L

disappears.

Note: Using keylock does not prevent the scanner from

TURNING THE BATTERY SAVE

FUNCTION OFF/ON

When the scanner is set to receive (monitor) a manually

selected channel, and it is not actively scanning, using

the battery save feature conserves energy.

To turn the battery save function off or back on, turn off

the scanner, then hold down PRIORITY and turn on the

scanner.

• OFF SAVE briefly appears when battery save has

been turned off.

• on SAVE briefly appears when battery save has

been turned on, and S appears.

When the battery save feature is active, the scanner re-

peatedly turns off the internal power for 1 second, then

turns it back on for about / second to check for a trans-

mission.

SKIPPING DATA SIGNALS

To prevent the scanner from stopping on channels that

consist of nonmodulated or data signals (such as fax or

modem transmissions) during a search or scan, turn on

the data skip feature. When the radio receives a data

signal and data skip is selected, the signal is ignored.

To turn on the data skip feature, turn off the priority fea-

ture if it is on (see “Priority” on Page 32), then press DA-

TA. DATA appears. To turn off the data skip feature,

press DATA again. DATA disappears.

Note: This feature does not apply to the air service band

as data signals are not generally found in this service.

RECEIVING NWR-SAME AND

WEATHER ALERT SIGNALS

In 1994, the National Oceanic and Aerospace Adminis-

tration (NOAA) began broadcasting alerts that include

digitally encoded data. Specific Area Message Encoding

(SAME) includes information which identifies the severity

of the alert. While this scanner does not encode specific

Special Features

geographical data, it does detect SAME signals and de-

code the alert level. The scanner displays this data as

codes corresponding to the levels of severity (L1, L2,

and L3).

Turning On the SAME Weather

Alert Feature

1. Press SVC (E) and select the weather search mode.

See “Service Bank Search” on Page 27.

2. Press ALT (DATA). ALERTappears. This mutes the

audio until the scanner receives a SAME-coded sig-

nal.

When the scanner receives a SAME-coded signal,

ALERTflashes and an associated “L” code (which indi-

cates the severity of the alert) appears, as well. The

scanner remains on the weather channel and the audio

turns on so you can hear the weather broadcast.

The scanner displays one of the following codes to indi-

cate the alert level.

L1: Warning

L2: Watch

L3: Statement

-----: Non-emergency

In addition to weather alerts, the scanner also receives

test and other event information. See “NWR-SAME

Code Detection Tests” on Page 37.

SAME Signal Detection Updating

When the scanner receives a SAME-coded signal, it re-

tains information about the most recent alert until you

turn off the power. Once the scanner detects an alert

code, ALERT flashes. To verify the specific alert level

(L1, L2, or L3) press SVC (E) to select the weather

search mode. Press ALT (DATA) to clear the alert.

Special Features

NWR-SAME Alert Tone Test

To hear and test the tones for the three alert levels,

press SVC (E) to select the weather service, then hold

down ALT for about 1 second. The tones sound in the or-

der L3, L2, then L1, and TEStflashes. Each alert code

appears as its tone sounds. Press any key to end the

test sequence.

NWR-SAME Code Detection Tests

The National Weather Service sends out daily, weekly,

and monthly test (and sometimes demonstration) sig-

nals, which let anyone with a receiver (such as the scan-

ner) verify that the equipment is working properly.

To find out the specific test schedule in your area, con-

tact your local NOAA or NWS office. Those offices are

usually listed in the telephone book under US Govern-

ment, Department of Commerce.

When ALERTappears, hold down ALT (DATA) for about

1 second. The frequency and TEStappear alternately.

When the scanner receives the test code, TEStalso ap-

pears.

To exit the test mode, press ALT (DATA) for about 1 sec-

ond.

Note: If an actual alert is sent, the scanner sounds the

appropriate tone and displays the corresponding alert

level.

Special Features

ˆ Trunking Operation

The scanner tracks transmissions that use the Motorola

Type I, Type II, hybrid, and Ericsson EDACS analog

trunking systems. The frequencies for many of the 800

MHz, 900 MHz, and EDACS public safety systems are

listed in the separate National Public Safety Trunked

System Frequency Guide included with your scanner.

TYPES OF TRUNKING SYSTEMS

This trunking scanner monitors two basic types of sys-

tems — the Motorola Type I/Type II or hybrid system,

and the Ericsson EDACS system. Instead of selecting a

specific frequency to transmit on, a trunked system

chooses one of several frequencies in a 2-way radio us-

er’s talk group when that user presses their PTT (push to

talk) control. Thus, trunking systems, in general, allocate

a few frequencies among many different users. Motorola

Type I and Type II systems achieve the same results in a

slightly different way. One important distinction between

these systems is the amount of data transmitted by each

radio when the operator pushes the PTT control. A Type I

system transmits the radio’s ID and its current affiliation

or the trunk system to which it belongs. A Type II system

only transmits the radio’s ID.

Why the difference? In Type I systems, each radio in the

trunk group individually transmits its own affiliation, while

the trunk system maintains a database that determines

each radio’s affiliation(s) in Type II systems.

Another difference between the systems is that Type I

systems are arranged in a fleet-subfleet hierarchy. For

example, it is possible for a city using a Type I system to

designate four fleets, each with eight subfleets.

The police department, fire department, utilities group,

and city administration could each be a separate fleet.

The police might decide to further divide its fleet into

subfleets, such as dispatch, tactical operations, detec-

tives, north, south, east, and west side patrols, and su-

pervisors. All the available police radios would then be

assigned to one of the police subfleets, letting the police

Trunking Operation

centralize their communications and control the type of

users on a single system. Determining the exact fleet-

subfleet hierarchy for a particular area is referred to as

fleet map programming.

The disadvantage of a Type I system is that the brief

burst of data sent when a user transmits must contain

the radio’s ID, its fleet information, and the subfleet infor-

mation as well. This is three times the amount of data a

Type II system radio sends. Since the data capacity of

Type I systems is limited and the total amount of data in-

creases with each user, Type I systems usually accom-

modate fewer users than Type II systems. Nevertheless,

Type I systems are still in use.

There are also hybrid systems which are a combination

of Type I and Type II. Your scanner is preset to monitor

Type II systems, but you can change to Type I or a hy-

brid of Type I and Type II systems by selecting a prepro-

grammed fleet map or creating a custom fleet map for

your area (see “Scanning Type I and Hybrid Trunked

Systems” on Page 51).

SETTING THE SCANNER TO THE

TRUNKING MODE

Simultaneous Trunking

The scanner allows you to track up to 10 systems at a

time. You can trunk scan or search and scan conven-

tional frequencies at the same time. You can also pro-

gram conventional frequencies in the same bank as

trunking systems.

After the scanner is finished checking activity in the

trunked system, it scans other conventional frequencies

in the bank. (Only trunking frequencies are programmed

in trunk mode.)

If a system is inactive for 1 second and there are no con-

ventional channels in the bank, the scanner starts scan-

ning the next selected trunk bank. If you turned DELAY

on, the scanner starts scanning the next trunk bank after

about 5 seconds.

Trunking Operation

To scan both trunking and conventional banks, select

the banks you wish to be active with trunking off, then

press TRUNK. The scanner begins scanning. To return

to conventional scanning, press TRUNK again.

SETTING SQUELCH FOR THE

TRUNKING MODE

Your scanner’s squelch setting is automatically adjusted

during trunking, which means it is not necessary to man-

ually adjust squelch while scanning trunked transmis-

sions. However, the squelch setting can affect how fast

your scanner acquires the data channel, and, in some in-

stances, can prevent your scanner from acquiring the

data channel at all.

We recommend you set SQUELCH fully clockwise before

selecting a trunked bank.

Note: Change this setting as needed for the best perfor-

mance in your area.

STORING TRUNKED FREQUENCIES

Follow these steps to select, program, and store trunked

frequencies.

1. Press PROG then TRUNK. TRUNKappears and one

or more bank numbers flash.

2. Press the number key (1–10) of the desired target

storage bank. Select one of the trunk systems by

repeatedly pressing 8 or 9 to select a trunking

system type, then press E (SVC). The scanner then

automatically selects the first channel in the

selected bank.

Note: You can select from the following six systems:

and the bank number, the channel number, and E

(EDACS) or M(Motorola) appears depending upon

the trunk system selected.

Notes:

• If you enter an invalid frequency (outside the

selected range), the scanner beeps, the channel

number flashes and Errorappears. If this hap-

pens, press MON/CLR ( ) to clear the frequency,

•

then repeat the entry.

• For EDACS systems, you must enter the fre-

quencies in logical channel number (LCN) order.

• If you try to enter a duplicate frequency in a bank,

the scanner beeps and the channel which was

previously stored appears.

• It is very important that you enter all the listed fre-

quencies for the selected agency in Step 3. Oth-

erwise, trunking will not occur when you press

SRC in Step 6.

4. Press either PROG or 8 to select the next channel

in the bank.

5. Repeat Steps 3 and 4 until you enter all desired fre-

quencies in that bank.

6. Press SCAN, then SRC to begin searching for the

trunk’s data channel and scan conventional fre-

quencies at the same time.

As the scanner looks through the frequencies, you

see them on the display. When the scanner finds

the controlling data channel, the scanner begins

trunking.

Trunking Operation

SEARCHING A TRUNKED BANK

Once the data channel is acquired, the scanner begins a

trunk search. With the search function, you will be able

to find all the active talk groups within the trunked sys-

tem. Press SCAN. You can switch to the trunk scan

mode from the trunk search mode. See “Scanning the

Talk Group ID Lists” on Page 50.

While scanning conventional frequencies, follow the

steps below to switch to the trunk mode after the scan-

ner finds the data channel.

1. Press TRUNK. The scanner begins scanning both

trunking and conventional banks.

2. Hold down SCAN for about 1 second. The scanner

switches to the trunk scan mode.

3. Hold down SRC for about 1 second. The scanner

switches to the trunk search mode.

Hint: While searching, you may not know exactly to

whom the talk group IDs are assigned until you listen

awhile. To locate talk group ID lists for your local police,

fire, and other agencies, refer to frequency guides avail-

able at your local RadioShack store or on internet sites

such as www.trunkscanner.com. You can also deter-

mine the type of agency you are listening to after a short

while, be it a police, fire, or emergency medical 2-way ra-

dio user. Once you have identified the type of service,

note the associated talk group ID of that unit for future

programming. See “Identifying a Trunked Frequency” on

Page 44. Determining the service associated with a talk

group ID might take awhile, but discovering the ID owner

of each signal is half the fun of trunk scanning!

Turning a Trunked Bank On or Off

Press DATA (ALT) during trunk scanning. The selected

trunked banks appear. Press the bank number (0–9), to

turn the desired bank on or off.

Trunking Operation

Skipping a Trunked Bank

You can scan conventional frequencies programmed in

the same bank by holding down SRC (LIMIT) for about 2

seconds. If there is no conventional frequency, the scan-

ner scans the next bank.

Turning the Status Bit Ignore (S-Bit)

On or Off

You can set how your scanner works with status bits

(also called S-Bits), letting you control how the scanner

interprets and displays talk group IDs.

The last four bits of a Motorola Type II talk group ID (a

binary 16-bit code) are the status bits. In some systems,

status bits identify special situations (such as an emer-

gency status).

Your scanner is preset to assume that the status bits in a

talk group ID are set to 0 and ignores them. For exam-

ple, when the scanner receives the talk group ID

010111001110 0011, it reads the ID as 010111001110

0000 and converts the first 12 bits of the ID to 23776 (the

talk group ID). However, since the status bit value is 3

(0011 converted to decimal equals 3), the ID is actually

23779.

If you are scanning a Motorola Type I system and do not

have a fleet map for that system, you might have to turn

off status bit ignore in order to determine the proper fleet

map.

Important: If you are scanning any system other than a

Motorola Type I system, be sure status bit ignore is set

to ONor you will miss some transmissions.

Follow these steps to turn status bit ignore on or off.

1. Hold down SCAN until the current status bit ignore

setting (ONor OFF) appears.

2. Press 8 to select ON or 9 to select OFF, then

press E (SVC).

Trunking Operation

Identifying a Trunked Frequency

While ID scanning (looking for IDs within a trunked sys-

tem) or performing an ID search, press 9 to see the

current trunked frequency. (The frequency flashes

twice.) Then hold down 9 until a confirmation tone

sounds and the ID and the frequency alternately appear.

To return to normal operation, press 9.

Selecting the EDACS Talk Group ID Format

The EDACS system uses two group ID formats: Decimal

and Agency-Fleet-Subfleet (AFS). If you use a list of IDs

shown in one format (for example AFS) and the ID you

want to receive is in the other format (for example, deci-

mal), press SVC (E) to switch to the decimal format. The

ID appears in decimal format. Eflashes on the display

when the decimal format is selected.

EDACS Talk Group ID Range Search

To search EDACS IDs faster, set a range for the Agency

or Fleet listings. Enter the Agency (or the Agency and

the Fleet) listing numbers using the number keys, then

press SRC (LIMIT). Note the following examples.

Example 1

Agency = 01

Press 0 1 . SRC (LIMIT)

01---appears during search.

Example 2

Agency = 01 Fleet = 01

Press 0 1 . 0 1 SRC (LIMIT)

01-01-appears during search.

To stop an ID range search, press SRC (LIMIT).

Using HOLD to Monitor an

Active Talk Group ID

Follow these steps to stop scanning and keep the scan-

ner tuned to a desired ID.

1. Press HOLD (A/B). HOLDappears and the scanner

stays on the current ID.

2. If you want to listen to (and hold) a different ID, use

the number keys to enter that ID.

3. Press HOLD (A/B) again. HOLD flashes, then the

scanner monitors the ID.

4. Press SRC to resume searching for a data channel

(trunk scanning).

Temporarily Storing a Talk Group ID

into the Monitor ID Memory

To store a talk group ID into a temporary monitor memo-

ry, press MON/CLR (•). This lets you store the ID prior to

moving it into a list memory. Press SRC to resume

searching.

Note: To program the ID stored in the monitor ID memo-

ry into the ID scan list, see “Moving Talk Group IDs to

Talk Group ID Lists” on Page 49.

Locking Out Talk Group IDs

Many municipal and commercial services use trunk sys-

tems to transmit signals from such devices as water

meter transmitters, door alarms, and traffic signals.

Some signals are encrypted, as well, and most are not

voice signals. Since all these are assigned IDs just like

other users, you may want to lock out reception of these

ID signals. You can lock out up to 100 IDs at one time.

Note: If you lock out an ID while searching, it is also

locked out of the scan list(s). See “Using Talk Group ID

Lists” on Page 48.

Trunking Operation

To lock out an ID, press L-OUT (S/S) when the ID ap-

pears. The ID is locked out, and the next active ID ap-

pears.

Unlocking a Single Talk Group ID

1. Hold down L-OUT (S/S) until you hear two short

beeps.

2. Repeatedly press 8 or 9 to select the ID you

want to unlock.

3. Press L-OUT (S/S). The ID is unlocked, and the

next locked ID appears.

4. Press SRC (LIMIT) to resume the scanner’s previ-

ously selected function.

Unlocking All Talk Group IDs

Hold down L-OUT (S/S) while searching until you hear

two short beeps, then press E (SVC) to unlock all the IDs

at once. The scanner beeps twice. Press L-OUT/SS to re-

sume the search.

Note: When you unlock all the IDs, the scan list appears.

Press SCAN to scan the IDs stored in your scan lists or

press SRC (LIMIT) to resume the scanner’s previously se-

lected function. For more information about scan lists,

see “Using Talk Group ID Lists” on Page 48.

Using Trunk Scanning Scan Delay

Sometimes a user might pause before replying to a

transmission. You can set the scanner to hold on an ID

for 5 seconds to wait for a reply. That way, the scanner

continues to monitor the ID for 5 seconds after the trans-

mission stops before resuming scanning.

Press DELAY to turn trunk scanning scan delay on or off.

DLYappears when the scan delay is set to on.

Note: If you consistently miss responses even with scan

delay turned on, change the default system type or the

fleet map being used. See “Scanning Type I and Hybrid

Trunked Systems” on Page 51.

Trunking Operation

Monitoring Talk Group IDs

You can use your scanner’s display to monitor the fre-

quencies/talk group IDs of a trunked system for activity.

While you cannot hear conversations in this mode, it is

an excellent way to determine which talk group IDs are

the most active. To set the scanner to monitor IDs, hold

down MON/CLR (•) until SEARCHand the channel num-

ber flash. All active group IDs appear in quick succes-

sion. To stop monitoring IDs, press SRC again.

Note: When you monitor IDs, any IDs you have locked

out also appear.

CHANNEL ACTIVITY BARS

Your scanner displays up to 20 channel activity bars for

the stored frequencies in a bank. These bars indicate the

activity taking place on a trunked system. By observing

these bars, you can see how many frequencies are be-

ing used and generally monitor how much communica-

tion traffic occurs.

Each frequency you store in a trunking bank has a corre-

sponding activity bar. However, there are only 20 bars

for a possible maximum of 50 frequencies. If the trunk

system contains more than 20 frequencies, some bars

will represent more than one frequency.

• If a bar appears steadily without any voice transmis-

sion, it represents the frequency in use as the data

channel.

• If a bar appears and flashes when an ID appears,

the bar represents the frequency being used by the

trunk system transmitter.

• If a bar appears without any voice transmission, the

channel is probably being used for a telephone

interconnect call or a private call, or the bar might

be a locked-out ID. Your scanner does not monitor

these types of calls.

• If the scanner is holding on an ID which is not being

used, the other activity bars turn on and off as other

groups use the system.

Trunking Operation

USING TALK GROUP ID LISTS

When you program trunked frequencies into a bank (see

“Storing Trunked Frequencies” on Page 40), your scan-

ner sets up five scan lists for that one bank in which you

can store your favorite IDs. Each list can contain up to

10 IDs, for a total of 50 IDs for each trunk scanning

bank. If you use all the banks as trunking banks, you can

store 1000 IDs.

Talk group ID lists help you to organize trunking system

users into categories. For example, you might use List 1

for police IDs, List 2 for fire department IDs, List 3 for

emergency medical service IDs, and so on. Once you

store all the IDs in a list, you can scan them just as you

scan conventional channels. You can program IDs into

talk group ID lists manually, during a search, or automat-

ically.

Manually Storing Talk Group IDs

in Talk Group ID Lists

1. Select the trunking bank you want to use (see

“Searching a Trunked Bank” on Page 42).

2. After the scanner begins trunk scanning, press

MAN. A number showing the current talk group ID

list appears at the top of the display, and bars

appear that show activity in other banks.

3. Press MAN again, then repeatedly press 8 or 9 to

select the talk group ID list location (shown at the

top of the display) where you want to store an ID.

Then press PROG.

4. Enter the type of ID you want to store, then press E.

To enter a Type I ID, use the number keys to enter

the block number and the fleet number, then press

. Enter the subfleet number and press E.

•

To enter an EDACS ID, use the number keys to

enter the agency number, then press . Next, enter

•

the fleet number and the subfleet number, then

press E.

Trunking Operation

Note: To clear a mistake while entering an ID, press

0 then E, then start over at Step 1.

5. Repeatedly press PROG or 8 to select the next

scan list location you want to program. Then repeat

Step 4 to enter another ID.

6. When you finish, press E to store the entries.

Entering EDACS Partial Talk Groups

You can enter partial group numbers in an EDACS talk

group. By entering only the desired portion of a group,

you can select either 128, 8, or 1 talk group. For exam-

ple, you might program every talk group in a police de-

partment by pressing just four keys.

Note: You cannot use partial talk groups in decimal

mode. (See “Selecting the EDACS Talk Group ID For-

mat” on Page 44.)

You can program a specific talk group such as 01-011

into the scan list memory. In AFS mode, you can pro-

gram the talk groups for an entire agency by pressing

corresponding keys.

For example:

You Press

To Scan

01 . E

all 01 groups

01 . 01 E

all 01 talk groups within

the 01 agency

To lock out a large number of talk groups, press L-OUT

after entering an agency or an agency and fleet into

memory.

Note: In AFS mode, agency numbers range from 00–15.

Moving Talk Group IDs to

Talk Group ID Lists

1. Press MAN. MANappears.

Trunking Operation

2. Select the ID scan list location where you want to

store the IDs, then press PROG. PGMappears.

3. Press MON/CLR. A monitor ID appears.

4. Press E. The scanner stores the IDs into the

selected ID scan list.

Scanning the Talk Group ID Lists

Press SCAN to begin scanning the lists you have stored.

Note: If one or more of the IDs you stored are incorrect,

Error flashes twice and the scanner beeps several

times, then the scan list numbers appear at the top of the

display. To correct the entry, delete at least one of the in-

correct IDs (see “Deleting a Stored Talk Group ID List”).

To remove a scan list from active scanning, use the

number keys to enter the scan list’s number. The scan

list number turns off, and the IDs in that list are not

scanned.

Note: One of the five scan lists must always be active.

You cannot remove all of them.

To restore a scan list to active scanning, use the number

keys to enter the number of the list again.

Press SRC to return to the previously selected function.

Deleting a Stored Talk Group ID List

1. Press PROG. PGMappears.

2. Repeatedly press 8 or 9 to select the talk group

ID list location (shown at the top of the display) you

want to delete.

3. Press 0 then E.

Priority Talk Group ID Scanning

You can assign a priority to a favorite ID so during scan-

ning the scanner checks that ID more frequently than the

others in the list. Each of the five memory locations re-

Trunking Operation

served for storing lists (see “Using Talk Group ID Lists”

on Page 48) can have only one priority ID, and the ID as-

signed that priority in List 1 has the highest priority of all.

To assign a priority to an ID, press PROG. Enter the de-

sired ID number (list number and location number), then

press PRIORITY (H/S). Pappears.

To turn priority ID scanning on or off, repeatedly press

PRIORITY (H/S) during ID scanning or manual operation.

PRIappears when priority scanning is turned on.

Note: Priority ID scanning does not operate when priori-

ty IDs are locked out. See “Locking Out Talk Group IDs”

on Page 45.

SCANNING TYPE I AND HYBRID

TRUNKED SYSTEMS

Your scanner is preset to scan Type II system IDs. When

you scan trunked frequencies, each Type II user ID you

see appears as an even number without a dash (exam-

ple 2160). Your scanner can also scan Type I trunked

systems. Each Type I ID appears as a three- or four-digit

number, followed by a hyphen, followed by a one- or

two-digit number (example 200-14).

If you notice a mix of odd- and even-user IDs (examples

6477, 2160, 6481, 6144, and 1167), then you are proba-

bly monitoring either a Type I or hybrid (a combination of

Type I and Type II user IDs) system with the S-Bit func-

tion turned off (see “Types of Trunking Systems” on

Page 38 and “Turning the Status Bit Ignore (S-Bit)

On or Off” on Page 43).

Subfleet information is included with the frequency list

for a Type I system. To enter the provided map, see

“Programming a Fleet Map” on Page 55.

Note: To locate suitable fleet map information, review

the contents of website www.trunkscanner.com.

If you do not already know the size codes used, you will

have to guess. Since you do not have to figure out all the

blocks at one time, this is not as hard as it might seem.

Trunking Operation

Select a size code for a block, then press SRC and listen

to the conversations. If you are receiving most of the re-

plies, then you have probably selected the right size

code and can program the next block of the map. There

are 16 preset fleet maps to choose from, and it is best to

start with these when setting up a Type I or hybrid trunk

scanning bank. If none of the following preset fleet maps

allow you to follow complete conversations, then you

probably need to program your own fleet map (see “Pro-

gramming a Fleet Map” on Page 55).

Selecting a Preset Fleet Map

1. Set the scanner for conventional scanning and

press PROG then TRUNK to select the bank to store

the fleet map.

2. Press a number key to select the bank to store the

fleet map.

3. Repeatedly press 8 or 9 to select E1, then press

E. A previously programmed trunked frequency

appears.

4. Press DATA (ALT).

5. Repeatedly press 8 or 9 to select the name of

the desired map (example E1P7). The prepro-

grammed fleet map appears.

6. Press E (SVC), then press SRC (LIMIT). The scanner

then searches for transmissions using the preset

map you chose.

Trunking Operation

Note: When the scanner searches for transmissions,

you see Type I fleet and subfleet IDs such as 100-12,

100-9, 000-12, or 400-8.

How do you know if the preset map you selected is cor-

rect? Listen to find out if you are following complete con-

versations. If not, try another preset map.

Programming a Fleet Map

1. Set the scanner for conventional scanning. Press

PROG then TRUNK.

2. Press the number key of the bank where you want

to store the fleet map.

3. Repeatedly press8 or 9 until E1 appears, then

press E. A trunked frequency you previously pro-

grammed appears.

4. Press DATA. A preprogrammed fleet map appears.

5. Repeatedly press 8 or 9 until USr appears.

Then press E.

6. Press DATA.

7. Repeatedly press 8 or 9 to select the size code

for the first block, then press E. The next available

block appears.

Size Code

Block

8. Repeat Step 7 until you have selected a size code

for each desired block.

9. Press SRC (LIMIT). The scanner exits the trunking

programming mode, tunes the data channel, then

searches using the map you programmed.

Trunking Operation

Note: If you select size code S-12, S-13, or S-14, these

restrictions apply:

• S-12 can only be assigned to Blocks 0, 2, 4, or 6

• S-13 can only be assigned to Blocks 0 and 4

• S-14 can only be assigned to Block 0

Since these size codes require multiple blocks, you will

be prompted for the next available block when you pro-

gram a fleet map. For example, if you assign Block 0 as

S-12, the scanner prompts you for b2, the next block

available, instead of b1. If you assign Block 0 as S-14,

you would not see another prompt because S-14 uses

all available blocks.

Programming the Base and

Offset Frequencies

To properly track Motorola VHF and UHF trunked sys-

tems, you must program the applicable base and offset

frequencies for each system.

For a list of these frequencies and other scanner infor-

mation, go to www.trunkscanner.com and other similar

frequency resources.

1. Set the scanner for conventional scanning. Press

PROG then TRUNK.

2. Press the number key of the bank where you want

to store the base frequency.

3. Repeatedly press 8 or 9 to select E2-VHi or

E2-UHF, then press E. A previously programmed

trunked frequency appears.

4. Press DATA (ALT). The preset base frequency

appears.

5. Enter a desired frequency.

6. Press DATA (ALT). The preset offset frequency

appears.

Trunking Operation

7. Enter the frequency using the number keys accord-

ing to the following guide:

• For Motorola Type II VHF, (E2-VHF Hi band) use

5kHz steps between 5 kHz – 100 kHz.

• For Motorola Type II UHF, (E2-UHF band) use

12.5kHz steps between 12.5 kHz – 100 kHz.

Programming a Hybrid System

A hybrid system is simply a Type I system with some of

its blocks designated as Type II blocks. To program a

hybrid system, follow the steps listed in “Programming a

Fleet Map” on Page 55. However, if you want a block to

be Type II, instead of pressing 8 or 9 to select the

size block (Step 7), enter size code S-0instead.

Turning On/Off the Motorola Disconnect

Tone Detect Function

While trunking a Motorola system, your scanner auto-

matically tunes to the data channel when it detects a dis-

connect tone (a code that tells the trunking system that

the transmitter has finished sending) on the voice chan-

nel.

You can manually turn off this function so the scanner

does not tune to the data channel under those condi-

tions. You might use this feature to listen to weak trans-

missions when conversations are generally disconnect-

ed.

To turn the disconnect tone detect function on or off, set

the scanner to trunk track then press SVC. The scanner

beeps and DATAflashes for about 5 seconds.

Notes:

• To set the scanner so it remains on the voice chan-

nel (even when a disconnect tone is transmitted or

there is no signal at all) set SQUELCH so you hear a

hissing.

Trunking Operation

• You cannot use the disconnect tone detect function

if you are programming a trunking frequency or a

fleet map.

To set the scanner to automatically tune to the data

channel once again when it detects a disconnect tone,

press SVC (E) .

Birdie Frequencies

Every scanner has birdie frequencies. Birdies are sig-

nals created by the scanner’s internal circuits. These

stray frequencies might interfere with broadcasts on the

same or similar frequencies. If you program one of these

frequencies, you hear only noise on that frequency. If the

interference is not severe, you might be able to turn

SQUELCH clockwise to cut out the birdie.

FREQUENCY CONVERSION

The tuning location of a station can be expressed in fre-

quency (kHz or MHz) or in wavelength (meters). The fol-

lowing information can help you make the necessary

conversions.

1 MHz (million) = 1,000 kHz (thousand)

To convert MHz to kHz, multiply the number of mega-

hertz by 1,000:

9.62 (MHz) × 1000 = 9620 kHz

To convert from kHz to MHz, divide the number of kilo-

hertz by 1,000:

2780 (kHz) ÷ 1000 = 2.780 MHz

To convert MHz to meters, divide 300 by the number of

megahertz:

300 ÷ 7.1 MHz = 42.25 meters

Caution: This procedure clears all the information you

have stored in the scanner. Before you reset the scan-

ner, try turning it off and on to see if it begins working

properly. Reset the scanner only when you are sure it is

not working properly.

Troubleshooting

1. Turn off the scanner.

2. While holding down 2 and 9, turn on the scanner.

memory properly.

ˆ Care and Maintenance

Your RadioShack 1000-Channel Handheld Trunking

Scanner is an example of superior design and crafts-

manship. The following suggestions will help you care

for your scanner so you can enjoy it for years.

Keep the scanner dry. If it gets wet, wipe

it dry immediately. Liquids might contain

minerals that can corrode the electronic

circuits.

Use and store the scanner only in normal

temperature environments. Temperature

extremes can shorten the life of electronic

devices, damage batteries, and distort or

melt plastic parts.

Keep the scanner away from dust and

dirt, which can cause premature wear of

parts.

Handle the scanner gently and carefully.

Dropping it can damage circuit boards

and cases and can cause the scanner to

work improperly.

Use only fresh batteries of the required

size and recommended type. Batteries

can leak chemicals that damage your

scanner’s electronic parts.

Wipe the scanner with a damp cloth occa-

sionally to keep it looking new. Do not use

harsh chemicals, cleaning solvents, or

strong detergents to clean the scanner.

Care and Maintenance

Modifying or tampering with the scanner’s internal

components can cause a malfunction and might inval-

idate its warranty and void your FCC authorization to

operate it. If your scanner is not performing as it

should, take it to your local RadioShack store for as-

sistance.
