900 MHz Hands-free Phone
FEATURES
Your RadioShack 900 MHz Hands-free Phone combines the clar-
ity of 900 MHz communication with portability and convenience.
The phone’s cordless keypad clips to your belt or clothing so you
can make and answer calls away from the base. The earphone
with microphone lets you keep your hands free while you talk.
Your phone has these features:
Ample Talk and Standby Time — when fully charged (about 12
hours), the supplied battery provides about 7 hours of talk time or
7 days of standby time.
Ten-Memory Speed Dial — stores up to ten frequently called
phone numbers for easy dialing.
Ten-Channel Auto Scan — automatically selects a clear channel
when you make or answer a call.
Security Access-Protection Code — prevents other cordless
phone users from using your phone line. Each time you place the
keypad on the base, the keypad automatically sets a new security
access-protection code.
Volume Control — lets you control the volume of the sound you
hear through the earphone.

2
Page — lets you send a paging signal from the base to the key-
pad to help locate a misplaced keypad or page someone at the
keypad.
Detachable Belt Clip — lets you carry the keypad on your belt or
clothing for easy portability.
Earphone Compartment with Cover — lets you store the ear-
phone when not in use.
Neck Strap Hole — lets you thread a neck strap (not supplied)
through the keypad and hang the keypad around your neck.
Your phone is ETL listed to UL standards and meets all applicable
FCC standards.

READ THIS BEFORE INSTALLATION
We have designed your phone to conform to federal regulations,
and you can connect it to most telephone lines. However, each
phone (and each device, such as a telephone or answering ma-
chine) that you connect to the telephone line draws power from
the telephone line. We refer to this power draw as the device's
ringer equivalence number, or REN. The REN is on the bottom of
your phone’s base.
If you use more than one phone or other device on the line, add
up all of the RENs. If the total is more than five (or three in rural ar-
eas), your telephones might not ring. If ringer operation is im-
paired, remove a device from the line.
Your phone complies with Part 68 of
FCC Rules
. You must, upon
request, provide the FCC registration number and the REN to
your telephone company. Both numbers are on the bottom of your
phone’s base.
Note: You must not connect your phone to:
• coin-operated systems
• party-line systems
• most electronic key telephone systems
This symbol is intended to inform you that impor-
tant operating and maintenance instructions are
included in the literature accompanying this prod-
uct.

Important:
• Cordless phones such as this one require AC power to oper-
ate. When the AC power is off, you cannot dial out or receive
incoming calls using your phone. For this reason, the phone
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.
• Some cordless phones operate at frequencies that might
cause interference to nearby TVs and VCRs. To minimize or
prevent such interference, the base of the cordless phone
should not be placed near or on top of a TV or VCR.
• Your cordless phone operates on standard radio frequencies,
as allocated by the FCC. Even though your phone's access
protection code prevents unauthorized use of your phone
line, it is possible for other radio units operating on similar fre-
quencies within a certain area to unintentionally intercept
your conversations and/or cause interference. This possible
lack of privacy can occur with any cordless phone.
THE FCC WANTS YOU TO KNOW
In the unlikely event that your phone causes problems on the
phone line, the phone company can temporarily discontinue your
service. If this happens, the phone company attempts to notify you
in advance. 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.

5
Also, the phone company can make changes to its lines, equip-
ment, operations, or procedures that could affect the operation of
this telephone. The telephone company notifies you of these
changes in advance, so you can take the necessary steps to pre-
vent interruption of your telephone service.
LIGHTNING
Your telephone has built-in protection circuits to reduce the risk of
damage from surges in telephone line and power line current.
These protection circuits meet or exceed the FCC requirements.
However, lightning striking the telephone or power lines can dam-
age your telephone.
Lightning damage is not common. Nevertheless, if you live in an
area that has severe electrical storms, we suggest that you unplug
your phone when storms approach to reduce the possibility of
damage.
FCC STATEMENT
The phone complies with the limits for a Class B digital device as
specified in Part 15 of
FCC Rules
. These limits provide reason-
able protection against radio and TV interference in a residential
area. However, your equipment might cause TV or radio interfer-
ence even when it is operating properly. To eliminate interference,
you can try one or more of the following corrective measures:
• Reorient or relocate the receiving antenna.
• Increase the distance between the equipment and the radio
or TV.

6
• Use outlets on different electrical circuits for the equipment
and the radio or TV.
Consult your local RadioShack store if the problem still exists.
PREPARATION
Selecting a Location
You can place the phone’s base on a flat surface such as a desk,
shelf, or table.
Select a location that is:
• near an easily accessible AC outlet
• near a telephone line jack
• out of the way of normal activities
• away from electrical machinery, electrical appliances, metal
walls, filing cabinets, wireless intercoms, security alarms, and
room monitors
The base’s location affects the phone’s range. If you have a
choice of several locations, try each to see which provides the
best performance.
Caution: The supplied AC adapter was designed specifically for
your phone. Use only the supplied adapter.
Your telephone connects directly to a modular telephone line jack.
If your telephone wiring does not have a modular jack, you can
update the wiring yourself using jacks and adapters (available at
your local RadioShack store), or have the telephone company up-

7
date the wiring for you. You must use compatible modular jacks
that are compliant with Part 68 of
FCC Rules
.
Note: The USOC number of the jack to be installed is RJ11C.
CONNECTING THE BASE
You can power the base using the supplied 12V, 200 mA AC/DC
adapter.
Cautions:
You must use a Class 2 power source that supplies
12V DC and delivers at least 200 mA. Its center tip
must be set to positive and its plug must fit the
phone's DC 12V 200mA jack. The supplied adapter meets
these specifications. Using an adapter that does not meet
these specifications could damage the phone or the adapter.
• Always connect the AC adapter to the phone before you con-
nect it to AC power. When you finish, disconnect the adapter
from AC power before you disconnect it from the phone.
Follow these steps to connect the base to a phone line and AC
power:
1. Plug one end of the supplied modular cord into the TEL LINE
jack on the back of the base.
2. Plug the modular cord’s other end into a modular phone line
jack.
3. Insert the supplied AC adapter’s barrel plug into the DC 12V
200mA jack on the back of the base.
4. Plug the adapter into a standard AC outlet.
!

5. Lift the base’s antenna to a vertical position.
Connecting, Charging, and
Replacing the Battery Pack
The phone comes with a rechargeable NiMH battery pack. You
must connect the battery pack and charge it for at least 12 hours
before you use the phone for the first time.
1. Press down and slide off the battery pack compartment cover.
2. Lift the battery pack out of the compartment.
3. Plug the battery pack’s connector into the socket in the com-
partment (the connector fits only one way), then replace the
battery pack.
4. Replace the cover.
To charge the battery pack, place the keypad faceup on the base.
The CHARGE/IN USE indicator lights.
Notes:
• Recharge the battery pack if the keypad beeps and the IN
USE/LOW BATT indicator on the keypad flashes while you
are using the phone, or if the IN USE/LOW BATT indicator
flashes when the phone is not in use.
• When you first use the phone after charging or recharging the
battery pack, the phone might not work. Return the keypad to
the base for about 5 seconds to reset the security access-
protection code.

9
• If the CHARGE/IN USE indicator does not light when you
place the keypad on the base, be sure the battery pack and
AC adapter are correctly and securely connected. Also,
check the charging contacts on the keypad and base. If the
contacts are dirty or tarnished, clean them with a pencil
eraser.
• If the battery pack becomes completely discharged or the
base loses power while the keypad is away from it, place the
keypad on the base for about 5 seconds to reset the security
access-protection code. If the keypad loses power, leave it on
the base to charge the battery pack.
• If you are not going to use your phone for an extended period
of time, disconnect its battery pack. This helps increase the
battery pack’s life.
• When the keypad is on the base, the CHARGE/IN USE indi-
cator lights even when the battery pack is not connected. If
your phone does not work, be sure the battery pack is prop-
erly connected.
The supplied battery pack should last about a year. If the battery
pack does not hold a charge for more than 2 hours after an over-
night charge, replace it with a new 3.6-volt, 600 mAh battery pack
with a connector that fits the socket in the battery compartment.
You can order a replacement battery pack through your local Ra-
dioShack store.
Note: To avoid losing numbers stored in memory, you must install
and begin charging the new battery pack within 2 minutes of re-
moving the old one.
Warning: Dispose of the old battery pack promptly and properly.
Do not burn or bury it.

10
Cautions:
• Be careful not to short the battery pack by touching it with
conducting materials, such as rings, bracelets, and keys. The
battery pack or conductor might overheat and burn.
• Do not open or mutilate the battery pack.
If you have trouble replacing the battery pack, take the phone to
your local RadioShack store for assistance.
Setting the Ringer
OFF/ON RINGER, on the right side of the handset, controls the key-
pad ringer. To have the phone ring when a call comes in, slide
RINGER to ON. To turn the ringer off, slide RINGER to OFF.
When RINGER is set to OFF, the phone does not ring, but you can
still make outgoing calls. If you hear an extension telephone ring,
you can answer the incoming call on this phone. The CHARGE/IN
USE indicator on the base and IN USE/LOW BATT on the keypad
indicator flash until you answer the call.
Setting the Dialing Mode
Set TONE/PULSE on the back of the base for the type of service
you have. If you are not sure which type you have, do this simple
test after charging the battery pack.
1. Set TONE/PULSE to TONE before use.
2. Press TALK so the CHARGE/IN USE indicator lights then lis-
ten for a dial tone.
3. Press any number other than 0and 1.

11
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.
If the dial tone stops
, you have touch-tone service. If the dial
tone continues, you have pulse service.
If you have tone service
, leave TONE/PULSE set to TONE. If
you have pulse service, set TONE/PULSE to PULSE.
4. To hang up, place the keypad on the base or press TALK.
Using the Earphone
1. Insert the earphone’s plug into the jack on the side of the
keypad.
2. Place the mono-earphone in either ear.
3. Move the clip along the earphone cord and clip it to your
clothing.
When you are not using the earphone, follow these steps:
1. Open the earphone compartment cover by pulling its tabs on
both sides.
2. Place the earphone in the compartment.
3. Close the compartment cover.
Using the Belt Clip
You can use the belt clip to hang the keypad on your belt or waist-
band for hands-free carrying. To attach the belt clip, snap the up-

12
per side of the clip into the slots on both sides of the keypad. To
remove the belt clip, pull out on either side of the clip.
OPERATION

Dial the number.
To answer a call, lift the keypad from the base, then press TALK.
The CHARGE/IN USE and IN USE/LOW BATT indicators light.
To end a call, place the keypad on the base or press TALK.
Notes:
• When you press a button, a single tone indicates that the
phone has accepted the command. Three tones indicate that
you pressed a button in error or there is severe interference.
(See “Changing Channels”).
• If interference is severe, the keypad might lose communica-
tion with the base and the call might disconnect. If this hap-
pens, return the keypad to the base for about 5 seconds to
reset the security access-protection code.

Note: The keypad beeps 3 times when you reach the lowest or
highest volume level.
Changing Channels
Every time you press TALK, the phone automatically selects a
clear channel it uses for communication between the keypad and
the base. If you hear interference during a call, repeatedly press
CH to change the channel until you get a clear one.
Using Redial
To redial the last number dialed, press TALK then REDIAL/PAUSE.
You can also redial a busy number quickly without hanging up the
phone. Press REDIAL/PAUSE.You hear a dial tone then the phone
automatically redials the number.
Notes:
• The redial memory holds up to 32 digits, so you can redial
long-distance as well as local numbers.
• The redial memory can also store tone and pause entries
(see “Using Tone Services on a Pulse Line” on Page 14 and
“Entering a Pause in a Memory Number” on Page 16).

14
Using Mute
To talk to someone else in the room without the person on the oth-
er end of the phone line hearing your conversation, press MUTE.
Press MUTE again to resume your phone conversation.
Using Flash
FLASH provides the electronic equivalent of a switchhook signal
for special phone service such as Call Waiting.
For example, if you have Call Waiting, press FLASH to answer an
incoming call without disconnecting the current call. Press FLASH
again to return to the first call.
Note: If you do not have any special phone services, pressing
FLASH might disconnect your current call.
Using Tone Services on a Pulse Line
Some special services, such as bank-by-phone, require tone sig-
nals. If you have pulse service, you can still use these tone servic-
es by following these steps:
1. Dial the service’s main number.
2. When the service answers, press TONE/∗
∗∗
∗. Any additional
numbers you dial are sent as tone signals.
3. After you complete the call, press TALK or return the keypad
to the base. The phone automatically resets to pulse dialing.

15
Using Page
You can send a page to the keypad to locate it when it is away
from the base and not in use. To page the keypad, press PAGE/
FIND on the base. The keypad rings for about 15 seconds. To find
the keypad, press and hold PAGE/FIND. The keypad rings for
about 1 minute. Press any key on the keypad or PAGE/FIND on the
base to silence it sooner.
MEMORY DIALING
You can store up to ten numbers of 16 digits each in the phone’s
memory.
Notes:
• To keep your accounts secure, we recommend you do not
store your personal access code for services such as bank-
by-phone in a memory location.
• When storing numbers for special services (such as alternate
long-distance or bank-by-phone), store the service’s main
phone number in one memory location and numbers for addi-
tional information in other locations.
Storing a Number in Memory
1. Press MEM on the keypad. The IN USE/LOW BATT indicator
flashes.
2. Dial the desired number (up to 16 digits including any pause
entries).
3. Press MEM again to store the number.

16
4. Press the memory location number (1–0) you want to store.
The keypad sounds two long beeps.
Note: If you hear three short beeps, you did not store the
number successfully. Begin again from Step 1.
5. Write down the stored name and number on the memory
label provided.
Note:
• If the low battery warning tone sounds while you are on the
phone and the IN USE/LOW BATT indicator flashes,
recharge or install the battery within 2 minutes, or the phone
will not retain the numbers stored in memory (see “Connect-
ing, Charging, and Replacing the Battery Pack” on Page 8).
• If you receive a call while you are storing a number in mem-
ory, press TALK to answer the call. After the call, begin again
at Step 1.
• To change a number stored in memory, simply store a new
number in that memory location.
Entering a Pause in a Memory Number
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, if you do, you should also store a pause after
the access code to allow the outside line time to connect. After en-
tering the access code, press REDIAL/PAUSE to enter a 2-second
pause.

17
Dialing a Stored Number
Press TALK. When you hear the dial tone, press MEM then the
memory location number (1–0). The phone dials the number.
Chain Dialing Service Numbers
To quickly recall special services numbers (such as alternate long
distance or bank by phone), store each group of numbers in its
own memory location.
When calling special services, dial the service’s main number first.
Then, at the appropriate place in call, press MEM, then the number
for the location where the additional numbers are stored.
Testing Stored Emergency Numbers
If you store an emergency service’s number (police department,
fire department, or ambulance, for example) and you want to test
the stored number, make the test call during the late evening or
early morning to avoid peak demand periods. Remain on the line
to explain the reason for your call.

18
TROUBLESHOOTING
We do not expect you to have any problem with your telephone,
but if you do, these suggestions might help.
Problem Suggestion
The keypad does
not work. Move the keypad closer to the base.
Raise the base’s antenna to a vertical position.
Make sure the phone’s modular cord and the AC
adapter are correctly and securely connected.
Make sure the keypad’s battery pack is properly
connected and charged (see “Connecting, Charg-
ing, and Replacing the Battery Pack” on Page 8).
Recharge the keypad’s battery pack.
Place the keypad on the base for about five sec-
onds to reset the security access-protection code.
The call is noisy. Keep the keypad and base away from interfer-
ence sources such as computers, remote control
toys, wireless alarm systems, wireless intercoms
and room monitors, fluorescent lights, and electri-
cal appliances. If the interference is severe, turn
off the device.
Move the keypad closer to the base.
Hang up and redial the number.
Press CH to change the channel.
The range
decreases. Make sure the base’s antenna is raised and is not touching a metal surface.
Recharge the keypad’s battery pack.

19
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 in-
stallation. If you cannot find the problem, take the phone to your
local RadioShack store for assistance.
CARE
Keep the phone dry; if it gets wet, wipe it dry immediately. Use
and store the phone only in normal temperature environments.
Handle the phone carefully; do not drop it. Keep the phone away
from dust and dirt, and wipe it with a damp cloth occasionally to
keep it looking new. Modifying or tampering with the phone’s inter-
nal components can cause a malfunction 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 Ra-
dioShack store for assistance. If the trouble is affecting the tele-
phone lines, the phone company can ask you to disconnect your
phone until you have resolved the problem.
You can receive but
not make calls. Set TONE/PULSE correctly for the type of service you have (see “Setting the Dialing Mode” on
Page 10).
