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.
