Powering Your CB Radio  
You can power your CB radio from one of these four sources:  
• The rechargeable Ni-MH battery pack  
• Eight AA batteries (not included) using the supplied battery  
case  
• AC power using an AC-to-DC power supply (not included)  
• Vehicle power using a DC power cord (not included)  
Using the Ni-MH Battery Pack  
Charge the Ni-MH battery pack (using the supplied AC charger)  
for about 18 hours prior to using it for the first time. Afterward,  
it takes 14-16 hours to charge the battery pack when it is fully  
discharged.  
You can charge the battery pack while it is installed or removed.  
But the CB radio does not work during charging.  
To charge the battery pack:  
Connect the AC Charger to the  
CHG Jack, then plug it into an AC  
outlet. The CHARGE Indicator  
lights red and charging starts.  
Note: The supplied AC charger  
is for charging only, not for  
directly powering the CB.  
Latch  
To install the battery pack:  
Slide the battery pack onto the  
CB radio until it clicks. The battery  
pack fits onto the CB radio only  
one way. Do not force it.

To remove the battery pack, slide  
the battery pack in the arrow  
direction while holding up the  
latch.  
Slide to remove  
battery pack  
Cautions:  
To avoid injury, do not connect  
 
the AC charger to a ceiling outlet. After charging, disconnect  
the AC charger.  
You must use a Class 2 power supply that provides 16V DC  
and delivers at least 200mA. The barrel plugs center must  
be positive and the barrel plug must fit the CBs CHG jack.  
The supplied AC charger meets these specifications. Using  
an adapter that does not meet these specifications could  
damage the CB radio or adapter.  
• Always connect the AC charger to the battery pack before  
you connect it to an AC outlet, and disconnect the AC  
charger from the AC outlet before you disconnect it from the  
battery pack.  
• Overcharging your battery pack could shorten its life.  
• Do not charge your battery pack at temperatures below 14°F  
(–10°C) or above 131°F (55°C).  
You cannot recharge the Ni-MH battery pack using DC  
power.  
Recycle Rechargeable Batteries  
Placing rechargeable batteries into the trash or the municipal  
waste system can be harmful to the environment and may be  
illegal in your area. RadioShack participates in an industry  
program to collect and recycle rechargeable batteries at the end  
of their useful life.  
You can return your rechargeable batteries to your local  
RadioShack store for recycling (at no cost to you). Or call  
1-800-THE-SHACK (1-800-843-7422) for information on  
rechargeable battery recycling in your area. RadioShack’s  
involvement in this program is part of the  
companys commitment to preserving our  
environment and conserving our natural  
resources.  
Using the AA Battery Case  
1. Turn off the CB radio if it is on.  
2. Pull the halves of the case apart to open  
it. Insert eight AA batteries, matching  
 
the polarity marks (+ and –). Snap the halves of the case  
together to close it.  
3. Slide the battery case onto the CB radio until it clicks. The  
battery case fits onto the CB radio only one way. Do not  
force it.  
Replace the batteries when the sound becomes weak or  
distorted,  
appears, or the CB radio stops working.  
;
Battery Notes:  
• Dispose of old batteries promptly and properly. Do not burn  
or bury batteries.  
• Use only fresh batteries of the required size and type.  
• Do not mix old and new batteries, different types of batteries  
(standard, alkaline, or rechargeable), or rechargeable  
batteries of different capacities.  
• If you do not plan to use the CB radio with batteries for two  
weeks or longer, remove the batteries. Batteries can leak  
chemicals that can destroy electronic parts.  
Using AC Power  
To power your CB radio from your home,  
you will need a 12V DC power supply  
that provides a minimum of 2.5A at 12V  
and a DC power cord (neither included).  
1. Turn off the CB radio if it is on.  
2. Use the DC power cord to connect  
the CBs 12V DC PWR Jack and the  
DC power supply.  
3. Connect the DC power supply to an  
AC outlet.  
12V DC PWR Jack  
4. Turn on the CB radio to use.  
Cautions:  
You must use a Class 2 power supply that provides regulated  
13.8V DC and delivers at least 2.5A. The barrel plugs center  
must be positive and the barrel plug must fit the CBs 12V  
 
DC PWR jack. Using an adapter that does not meet these  
specifications could damage the CB radio or adapter.  
• Always connect the power supply to the CB radio before you  
connect it to an AC outlet, and disconnect the power supply  
from the AC outlet before you disconnect it from the CB  
radio.  
Using Vehicle Power  
To power your CB radio from your vehicle, you will need a DC  
power cord (not included). You may also need a roof-mounted  
antenna to improve transmission quality and increase the  
transmission range.  
1. Turn off the CB radio if it is on.  
2. Use the DC power cord to connect the CBs 12V DC  
PWR jack and the vehicles 12V power source, such as the  
cigarette-lighter socket.  
3. Turn on the CB radio to use.  
Cautions:  
You must use a Class 2 power supply that provides regulated  
12V DC and delivers at least 2.5A. The barrel plugs center  
must be positive and the barrel plug must fit the CB radios  
12V DC PWR jack. Using an adapter that does not meet  
these specifications could damage the CB radio or adapter.  
• Always connect the power supply to the CB radio before you  
connect it to the vehicle outlet, and disconnect the power  
supply from the outlet before you disconnect it from the CB  
radio.  
 
Connecting Your CB Radio  
Installing the Antenna  
To install the supplied antenna, align  
the two slots on the antenna connector  
with the tabs on the BNC connector  
of the CB radio. Push the antenna  
connector to the CB radio and rotate  
the antenna connector clockwise until it  
locks into place.  
Installing an Optional Antenna  
The CBs BNC connector allows you to use a variety of optional  
antennas, including external mobile antennas and outdoor base  
station antennas.  
Always use the 50-ohm, RG-58, or RG-8 coaxial cable to connect  
an outdoor antenna. If the antenna is over 50 feet from the CB  
radio, use the RG-8 low-loss dielectric coaxial cable.  
Safety Precaution:  
If an outside antenna is installed, be sure the antenna system is  
grounded so as to provide protection against voltage surges and  
built-up static charges. When installing the antenna, be careful not  
to touch overhead power lines as contact with them might be fatal.  
Connecting an External Speaker or Microphone  
Connect an external speaker (not  
included) to the SPK jack of your  
CB radio. This mutes the CBs  
internal speaker.

Safety Precaution  
Your wireless hand-held portable transceiver contains a low  
power transmitter. When the Push-to-Talk (PTT) button is  
pushed it sends out radio frequency (RF) signals. The device is  
authorized to operate at a duty factor not to exceed 50%. In  
August 1996, the Federal Communications Commissions (FCC)  
adopted RF exposure guidelines with safety levels for hand-held  
wireless devices.  
To maintain compliance with the FCCs RF exposure guidelines  
hold the transmitter and antenna at least 1 inch (2.5 centimeters)  
from your face and speak in a normal voice, with the antenna  
pointed up and away from the face. If you wear the handset  
on your body while using the headset accessory, use only the  
supplied belt clip for this product and when transmitting, take it  
out of the belt to ensure that the antenna is at least 1 inch (2.5  
centimeters) from your body.

Understanding Digital Weather Alert  
The weather service precedes each weather alert with a digitally-  
encoded SAME (Specific Area Message Encoding) signal, then  
a 1050 Hz tone. When your local weather station broadcasts  
a weather alert signal, the CB radio sounds an alert tone and  
displays a message showing the alert level.

Notes:  
• The CB radio does not display the actual location referenced  
by SAME messages. It uses only the message portion of the  
SAME signal.  
• If severe weather threatens, do not wait for an alert tone;  
tune to the weather broadcast and monitor the weather  
information.  
• If a weather signal ends, the CB radio beeps three times  
(when the key tone is turned on) and only when the weather  
signal ends the first time, then WX flashes to indicate there is  
no signal.
