Mute — prevents the person on the oth-  
er end of the phone line from hearing  
your conversation with someone in the  
room.  
This symbol is intended to alert  
you to the presence of uninsu-  
lated dangerous voltage within  
the product’s enclosure that might  
be of sufficient magnitude to con-  
stitute a risk of electric shock. Do  
not open the product’s case.  
Flash — sends an electronic switch-  
hook signal for use with special phone  
services such as Call Waiting.  
This symbol is intended to inform  
you that important operating and  
maintenance instructions are  
included in the literature accom-  
panying this product.  
Redial — lets you quickly dial the last  
number dialed.  
!
Hearing Aid Compatible — lets you  
use this telephone with hearing aids that  
have a T (telephone) switch.  
Important:  
• Cordless phones such as this one  
require AC power to operate. When  
AC power is off, you cannot dial out  
or receive incoming calls using your  
ET-927. For this reason, the ET-927  
should not be your only telephone.  
To be safe, you should also have a  
phone that does not require AC  
power to operate (not a cordless  
phone), so you can still make and  
receive calls if there is an AC power  
failure.  
Three Mounting Options — let you  
place the phone on a desk top, or mount  
it on a wall plate or directly on a wall.  
This phone has been tested and found  
to comply with all applicable UL and  
FCC standards.  
WARNING: To reduce the risk of fire or  
shock hazard, do not expose this product to rain  
or moisture.  
• Some cordless phones operate at  
frequencies that might cause inter-  
ference to nearby TVs and VCRs.  
To minimize or prevent such interfer-  
ence, the base of the cordless  
phone should not be placed near or  
on top of a TV or VCR.  
CAUTION  
RISK OF ELECTRIC SHOCK.  
!
DO NOT OPEN.  
CAUTION: TO REDUCE THE RISK OF  
ELECTRIC SHOCK, DO NOT REMOVE  
COVER OR BACK. NO USER-SERVICE-  
ABLE PARTS INSIDE. REFER SERVICING  
TO QUALIFIED PERSONNEL.

INSTALLATION  
FCC STATEMENT  
This telephone complies with Part 68 of  
FCC Rules. You must, upon request,  
provide the FCC Registration Number  
and the REN to your phone company.  
These numbers are on the label on the  
bottom of the base.  
Your telephone conforms to federal reg-  
ulations, and you can connect it to most  
telephone lines. However, each device  
you connect to the phone line draws  
power from the phone line. We refer to  
this power draw as the device’s ringer  
equivalence number, or REN. The REN  
is on the bottom of the base.  
You must not connect your phone to any  
of the following:  
• coin-operated systems  
If you are using more than one phone or  
other device on the line, add up all the  
RENs. If the total is more than five (three  
in rural areas), your phone might not  
ring. If ringer operation is impaired, re-  
move a device from the line.  
• party-line systems  
• most electronic key phone systems

INSTALLATION  
• The USOC number of the jack to be  
installed is RJ11C (RJ11W if you  
want to mount it on a wall plate).  
INSTALLING THE  
HANDSET’S  
ANTENNA  
Power the ET-927 using the supplied  
9V, 500-mA AC adapter.  
illus  
Insert the antenna into the  
hole on the top of the hand-  
set, then twist the antenna  
clockwise until it is secure.  
Cautions:  
You must use a Class 2  
power source that supplies  
!
9V DC and delivers at least  
500 mA. Its center tip must be set to  
positive and its plug must fit the ET-  
927's DC 9V jack. The supplied  
adapter meets these specifications.  
Using an adapter that does not meet  
these specifications could damage  
the phone or the adapter.  
SELECTING A LOCATION  
You can place the phone on a desk top,  
or mount it on a wall plate or directly on  
a wall. Select a location that is:  
• near an AC outlet  
• near a telephone line jack  
• Always connect the AC adapter to  
the ET-927 before you connect it to  
AC power. When you finish, discon-  
nect the adapter from AC power be-  
fore you disconnect it from the  
phone.  
• away from electrical machinery,  
electrical appliances, metal walls or  
filing cabinets, wireless intercoms,  
alarms, and room monitors  
• away from other cordless phones  
The base’s location affects the phone’s  
range. If you have a choice of several lo-  
cations, try each to see which provides  
the best performance.  
Placing on a Desk Top  
1. Push in the two tabs on the top of

PREPARATION  
Notes:  
• You can hang the handset face up  
CONNECTING AND  
CHARGING THE BATTERY  
PACK  
on the base if it is wall-mounted  
(using the slot on the back of the  
handset); however, the battery pack  
will not fully charge in this position.  
The ET-927 comes with a rechargeable  
nickel-cadmium battery pack in the  
handset, but not connected. Before us-  
ing your phone, you must connect the  
battery pack, then charge it for about 24  
hours.  
• When you first use your phone after  
charging or recharging the battery  
pack, the handset might not work or  
it might sound an error tone when  
you press TALK. If this happens,  
place the handset on the base for  
about 5 seconds, then try again.  
1. Slide off the handset’s battery com-  
partment cover.  
• If the CHARGE indicator does not  
light when you place the handset on  
the cradle, be sure the battery pack  
and AC adapter are correctly and  
securely connected.

socket. The connector  
fits only one way.  
3. Replace the cover.  
Also, check the charging contacts  
on both the handset and base. If the  
contacts are dirty or tarnished, clean  
them with a pencil eraser.  
To charge the battery pack, place the  
handset on the base.  
Recharge the battery pack when the  
BATT LOW indicator on the handset  
lights.

If the battery and AC connections  
are correct and secure and the  
charging contacts are clean, the bat-  
tery might be fully charged. This is  
not a malfunction.

43-1097a.fm Page 12 Tuesday, August 31, 1999 10:01 PM  
• If the phone stops operating prop-  
erly, check the base’s phone line  
cord and AC adapter connections. If  
the connections are secure but the  
phone still does not work, unplug  
the base’s AC adapter from the AC  
outlet and disconnect the handset’s  
battery pack. Wait 3 minutes, then  
reconnect the battery pack and plug  
the AC adapter back into the AC  
outlet. The phone should operate  
properly.  
SETTING THE DIALING  
MODE  
Set T/P (Tone/Pulse) for the type of ser-  
vice you have. If you are not sure which  
type you have, do this test after the bat-  
tery pack is fully charged.  
1. Set T/P on the back of base to T.  
Illus  
• If the battery pack becomes weak,  
the handset sounds a short beep  
every 16 seconds during a call and  
the BATT LOW indicator flashes.  
Within about 10 minutes, the phone  
will automatically disconnect. Re-  
charge the battery pack.  
2. Press TALK and listen for a dial  
tone.  
Illus  
• If the battery pack loses its charge  
completely or the base loses power  
while the handset is away from it,  
the security access-protection code  
needs to be reset. To reset the secu-  
rity code, place the handset on the  
base. If it was the handset that lost  
power, leave the handset on the  
base to charge the battery pack.  
3. Press any number other than 0.  
Note: If your phone system requires  
that you dial an access code (9, for  
example) before you dial an outside  
number, do not press the access  
code either.  
• About once a month, fully discharge  
the battery pack by keeping the  
handset off the base until the BATT  
LOW indicator turns on. Otherwise,  
it loses its ability to fully recharge,  
and you might have to recharge and  
replace it more often.  
If the dial tone stops, you have  
touch-tone service. Leave T/P set to  
T.  
If the tone continues, you have  
pulse (rotary) service. Set T/P to P.  
4. To hang up, either place the handset  
on the base or press TALK so the  
TALK indicator on the handset and  
the IN USE indicator on the base  
turn off.

43-1097a.fm Page 13 Tuesday, August 31, 1999 10:01 PM  
Note: Even if you turn off the ringer on  
the handset or base, you can still make  
calls using that keypad, and you can still  
answer calls if you hear another phone  
on that same line ring (see “Operation”  
on Page 14).  
ADJUSTING THE  
RINGERS  
The ET-927’s handset and base each  
have four different ringer tones. You can  
set the base’s and handset’s ringer tone,  
or turn off the ringer on either or both.  
Setting the Ringer’s Volume  
Turning On/Off the Ringers  
To adjust the ringer’s volume when the  
phone is not in use, repeatedly press  
VOLUME or on the handset.  
To have the base ring when a call  
comes in, set RINGER ON/OFF on the  
back of the base to ON.  
Checking/Setting the Ringer  
Tone  
Illus  
The base and handset are both preset  
to use the same ringer tone (1). To  
change or hear the different tones, press  
FLASH then 1, 2, 3, or 4 when the phone  
is not in use. (The last number button  
you pressed is the tone you will hear.)

SPECIAL FEATURES  
at the appropriate place in the  
sequence of numbers.  
MEMORY DIALING  
You can store up to 20 numbers of up to  
16 digits each in the ET-927’s memory,  
then dial them with the press of a few  
buttons.  
• Each  
or pause entry (see  
“Storing a Pause”) counts as one  
digit in memory.  
3. Press MEM then press the number  
key (0120) of the memory location  
where you want to store the number.  
The ET-927 beeps twice and stores  
the number.  
Storing a Number  
Notes:  
• You must complete these steps  
within 30 seconds of each other. If  
you do not, the ET-927 sounds a  
long beep, all indicators stop flash-  
ing, and you must start over again at  
Step 1.  
Notes:  
To change a number in memory,  
store a new one in its place.  
To erase a number from memory,  
repeat Steps 1 and 3, skipping Step  
2.  
• You can store special banking or  
telephone service numbers (such as  
access codes or account numbers)  
in memory, but for security pur-  
poses, we recommend that you do  
not store private numbers (such as  
personal identification numbers or  
passwords) in memory.  
Storing a Pause  
In some telephone systems, you must  
dial an access code (9, for example) and  
wait for a second dial tone before you  
can dial an outside number. You can  
store the access code with the phone  
number. However, you should also store  
a pause after the access code to allow  
the outside line time to connect.  
1. Press MEM (memory) on the hand-  
set. The TALK indicator on the  
handset and IN USE indicator on  
the base flash.  
To add one or more 2-second pauses to  
a phone number you are storing in  
memory, press REDIAL at each point  
where a pause is needed.  
Illus  
Note: Each pause entry counts as one  
digit in memory.  
2. Enter the number you want to store.

Dialing a Stored Number  
USING THE INTERCOM  
To dial a stored number, when you hear  
the dial tone, press MEM then the de-  
sired memory location number (0120).  
You can use the ET-927 as a two-way  
pager and intercom between the base  
and the handset. This is useful if the  
handset is away from the base and you  
want to locate it, or if you want to have a  
conversation between someone with the  
handset and someone at the base.  
Chain Dialing Service Numbers  
You can make a call using more than  
one of the ET-927’s memory locations.  
This is called chain dialing. Chain dialing  
is useful for dialing special services such  
as alternate long distance or bank-by-  
phone.  
Notes:  
• If a call comes in during an intercom  
conversation, the person using the  
handset can answer the call, but the  
intercom call is disconnected.  
When calling special services, dial the  
service’s main number first. Then, at the  
appropriate place in the call, press MEM  
and the number for the memory location  
where the additional information is  
stored.  
• If the handset is in use when it  
receives a page, the person using  
the handset hears one quiet ring  
over the phone.  
Paging from the Base to the  
Handset  
Testing Stored Emergency  
Numbers  
To send a page from the base to the  
handset, press PAGE on the base. The  
handset beeps twice per second for 15  
seconds. The base’s PAGE indicator  
flashes while the handset beeps.  
If you store an emergency service’s  
number (police department, fire depart-  
ment, ambulance) and you want to test  
the stored number, make the test call  
during the late evening or early morning  
hours to avoid peak demand periods. Al-  
so, remain on the line to explain the rea-  
son for your call.

USING AN OPTIONAL  
HEADSET  
Your ET-927’s handset is equipped with  
a headset jack on top. This jack allows  
you to connect a headset for hands-free  
conversation — perfect for when you are  
working in the yard or garage. A handset  
holder carries the handset for you while  
you use the headset. (Headsets and  
handset holders are available at your lo-  
cal RadioShack store.)

Problem  
Solution  
The phone does not work or works  
poorly.  
Be sure the base’s phone line cord and  
AC adapter are correctly and securely  
connected. If that does not help, unplug  
the base’s AC adapter from the AC outlet  
and disconnect the handset’s battery  
pack. Wait 3 minutes, then reconnect the  
battery pack and plug the AC adapter  
back into the AC outlet.  
The handset battery pack does not  
charge.  
Check the charging contacts on the  
handset and base. If they are dirty, clean  
them with a pencil eraser.  
The handset does not ring or receive  
a page.  
Be sure the handset’s ringer is turned on.  
Adjust the base’s antenna so it stands  
straight up.  
Move closer to the base.  
Move the base away from noise sources.  
The battery pack might be weak. Charge  
the battery pack by placing the handset  
on the base for 15–24 hours.  
Return the handset to the base to reset  
the security code.  
The handset stops working or works  
poorly during a call.  
Move the handset closer to the base.  
Adjust the base’s antenna so it stands  
straight up.  
Be sure the handset’s battery pack is  
charged. (If the battery power is too low,  
it does not have enough power to light  
the BATT LOW indicator.)  
If you still have problems, disconnect the phone. If other phones on the same line  
work properly, the fault is in this phone or its installation. If you cannot find the prob-  
lem, take your phone to your local RadioShack store for assistance.

OUT-OF-RANGE  
INDICATIONS  
If you move the ET-927’s handset out of  
the base’s range, the handset will not  
operate properly.  
If you move the handset out of the  
base’s range when the handset is not in  
use, the handset’s BATT LOW indicator  
flashes and the handset beeps twice at  
16-second intervals. When you move  
the handset back within range of the  
base again, the out-of-range indications  
stop.  
If you move the handset out of the  
base’s range while a call is in progress,  
two beeps sound through the earpiece  
every 3–4 seconds and the BATT LOW  
indicator flashes, and you and the other  
party cannot hear each other.  
If you move the handset back within the  
base’s range within 30 seconds, the out-  
of-range indications stop, and you can  
resume your phone conversation.  
If you keep the handset out of the base’s  
range for 30 seconds or more, two  
beeps sound through the earpiece every  
3–4 seconds and the BATT LOW indica-  
tor flashes. After 30 seconds, the call is  
disconnected, the handset beeps twice  
every 16 seconds and the BATT LOW  
indicator keeps flashing. When you  
move the handset back within range of  
the base again, the out-of-range indica-  
tions stop.

CARE AND MAINTENANCE  
Your RadioShack ET-927 Digital Spread Spectrum 900 MHz Cordless Telephone is  
an example of superior design and craftsmanship. The following suggestions will help  
you care for your phone so you can enjoy it for years.  
Keep the phone dry. If it gets wet, wipe it dry immediately. Liquids might  
contain minerals that can corrode the electronic circuits.  
Use and store the phone only in normal temperature environments. Tem-  
perature extremes can shorten the life of electronic devices, damage bat-  
teries, and distort or melt plastic parts.  
Keep the phone away from dust and dirt, which can cause premature wear  
of parts.  
Handle the phone gently and carefully. Dropping it can damage circuit  
boards and cases and can cause the phone to work improperly.  
Use only fresh batteries of the required size and recommended type. Bat-  
teries can leak chemicals that damage your phone’s electronic parts.  
Wipe the phone with a damp cloth occasionally to keep it looking new. Do  
not use harsh chemicals, cleaning solvents, or strong detergents to clean  
the phone.  
Modifying or tampering with the phone’s internal components can cause a malfunc-  
tion and might invalidate its warranty and void your FCC authorization to operate it. If  
your phone is not performing as it should, take it to your local RadioShack store for  
assistance. If the trouble is affecting the telephone lines, the phone company can ask  
you to disconnect your phone until you have resolved the problem.

Cautions:  
REPLACING THE  
BATTERY PACK  
• Use only a replacement battery  
pack of the required type (3.6V, 600  
mAh rechargeable battery pack).  
If you follow the instructions in “Connect-  
ing and Charging the Battery Pack” on  
Page 11, the battery pack should last  
about one year. If the battery pack will  
not hold a charge for more than 2 hours  
after an overnight charge, replace it with  
a new 3.6V, 600 mAh battery pack that  
has a connector which fits the socket in  
the battery compartment. You can order  
a replacement battery pack through your  
local RadioShack store.  
• Be careful not to short the battery  
pack with conducting materials,  
such as rings, bracelets, and keys.  
The battery pack or conductor might  
overheat and burn.  
Important: This phone’s  
battery pack uses nickel-  
cadmium rechargeable  
batteries. At the end of a  
nickel-cadmium 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 avail-  
able are: municipal curbside collection,  
drop-off boxes at retailers such as your  
local RadioShack store, recycling collec-  
tion centers, and mail-back programs.

Install the new battery pack as de-  
scribed here, then charge the battery  
pack for 24 hours.  
Note: To avoid losing phone numbers  
stored in memory, try to install and begin  
charging the new battery pack within  
about 2 minutes.  
1. Press down and slide off the hand-  
set’s battery compartment cover.  
Warnings:  
Illus  
• Dispose of the old battery pack  
promptly and properly. Do not burn  
or bury it.  
2. Gently pull out the battery connector  
to disconnect it, then remove the  
battery pack.  
• Do not open or mutilate the battery  
pack. Swallowing battery parts can  
be fatal.  
3. Insert a fresh battery pack and plug  
its connector with the flat side up  
into the socket inside the battery  
compartment. The connector fits  
only one way.  
4. Replace the cover.

To eliminate interference, you can try  
one or more of the following corrective  
measures:  
THE FCC WANTS YOU TO  
KNOW  
In the unlikely event that your phone  
causes problems on the phone line, the  
phone company can temporarily discon-  
tinue your service. The phone company  
normally attempts to notify you in ad-  
vance. If advance notice is not practical,  
the phone company notifies you as soon  
as possible and advises you of your  
right to file a complaint with the FCC.  
• Reorient or relocate the receiving  
antenna.  
• Increase the distance between the  
equipment and the radio or TV.  
• Use outlets on different electrical cir-  
cuits for the equipment and the  
radio or TV.  
Consult your local RadioShack store if  
the problem still exists.  
Also, the phone company can make  
changes to its lines, equipment, opera-  
tions, or procedures that could affect the  
operation of this telephone. The phone  
company normally notifies you of these  
changes in advance, so you can take  
the necessary steps to prevent interrup-  
tion of your phone service.  
LIGHTNING  
Your phone has built-in protection cir-  
cuits to reduce the risk of damage from  
surges in phone line current. These pro-  
tection circuits meet or exceed FCC re-  
quirements. However, lightning striking  
the phone lines can damage your  
phone.  
This equipment complies with the limits  
for a Class B digital device as specified  
in Part 15 of FCC Rules. These limits  
provide reasonable protection against  
radio and TV interference in a residential  
area. However, your equipment might  
cause TV or radio interference even  
when it is operating properly.  
Lightning damage is not common. Nev-  
ertheless, if you live in an area which  
has severe electrical storms, we sug-  
gest that you unplug your phone during  
storms to reduce the possibility of dam-  
age.
