INTRODUCTION
RadioShack welcomes you to the
next generation of personal commu-
nication —the Family Radio Ser-
vice (FRS). FRS is a new license-
free, two-way, short-range voice ra-
dio service that lets families and
groups keep in touch with each oth-
er on specific reserved channels.
Your RadioShack Personal FM
Transceiver is a lightweight, palm-
sized radio that you can carry al-
most anywhere.
To eliminate interference from other
users on the same channel, select
another channel or use the quiet
feature (see “Using the Quiet Fea-
ture” on Page 6). With one of the 38
available quiet codes set and the
quiet feature activated, you only
communicate with FRS radios
which are tuned to the same chan-
nel and quiet code as your radio.
Your radio has
auto-squelch
, which
means you won’t hear anything on a
channel unless someone is trans-
mitting nearby on the same chan-
nel. You can use the MON (monitor)
key to temporarily turn off auto-
squelch and hear weaker, distant
transmissions.

PREPARATION
Your radio uses 4 AA batteries (not
supplied) for power. We recom-
mend alkaline batteries (available at
your local RadioShack store). You
can also use rechargeable nickel-
cadmium batteries (such as Cat.
No. 23-325) and charge them in the
radio with an AC adapter (Cat. No.
273-1662). See “Charging Re-
chargeable Ni-Cd Batteries” on
Page 4.
Caution: Do not mix old and new
batteries, different types of batteries
(standard, alkaline, or recharge-
able), or rechargeable batteries of
different capacities.
1. Rotate VOLUME fully counter-
clockwise, then press the tab
on the battery compartment
cover and open the cover.
2. Slide the switch inside the
compartment to ALKALINE (for
alkaline batteries) or Ni-Cd (for
rechargeable nickel-cadmium
batteries).
3. Install the batteries according
to the polarity symbols (+ and
–) marked inside the cover,
then close the cover.
When appears, replace the
batteries.

Caution: Dispose of old batteries
promptly and properly. Do not burn
or bury them.
Charging Rechargeable
Ni-Cd Batteries
Caution: You must use an AC
adapter that supplies 7.5 volts and
delivers at least 300 mA. Its center
tip must be set to positive and its
plug must fit the radio’s CHRG jack.
The recommended adapter meets
these specifications; using an
adapter that does not could dam-
age the radio or the adapter.
Note: Charge only Ni-Cd batteries
in the radio. To prevent overcharg-
ing, use an external charger to
charge Ni-MH batteries.
1. Turn off the radio and open
the battery compartment.
2. Slide the switch inside the
compartment to Ni-Cd.
3. Put 4 AA Ni-Cd batteries in the
compartment as shown on the
back of the radio, then close
the cover.
4. Attach the adapter’s 3.4 mm
outer diameter/1.3 mm inner
diameter plug to the adapter
and set the tip to positive (+).
5. Connect the adapter’s plug to
the radio’s CHRG jack and plug
its other end into a standard
AC outlet.
6. When charging is complete
(about 15 hours), disconnect
the adapter from the outlet
and the CHRG jack.

CARE
To enjoy your radio for a long time:
• Handle it gently.
• Keep it away from dust, mois-
ture, and temperature ex-
tremes.
• Clean it with a damp cloth. Do
not use harsh chemicals.
Modifying or tampering with the ra-
dio’s internal components can
cause a malfunction and might in-
validate the radio’s warranty and
void your FCC authorization to op-
erate it. If your radio is not perform-
ing as it should, take it to your local
RadioShack store for assistance.
FCC INFORMATION
Important: Do not open your radio
to make any internal adjustments.
Your radio is set up to transmit a
regulated signal on one of 14 as-
signed frequencies. It is against the
law to alter or adjust the settings in-
side the radio to exceed those limi-
tations. Any adjustments to your
radio must be made by a qualified
technician using the proper test
equipment. To be safe and sure:
• Never open your radio’s case.
• Never change or replace any-
thing in your radio except the
batteries.

Your radio might cause TV or radio
interference even when it is operat-
ing properly. To determine whether
your radio is causing the interfer-
ence, turn it off. If the interference
goes away, your radio is causing it.
Try to eliminate the interference by:
• moving your radio away from
the receiver
• calling your local RadioShack
store for help
If you cannot eliminate the interfer-
ence, the FCC requires that you
stop using theradio.
This device complies with Part 15 of
the
FCC Rules
. Operation is subject
to the following two conditions: (1)
This device may not cause harmful
interference, and (2) this device
must accept any interference re-
ceived, including interference that
may cause undesired operation.
