PREPARATION
INSTALLING BATTERIES
Your radio uses three AA batteries for power. For the
longest life, we recommend alkaline batteries (avail-
able from your local RadioShack store). You can also
use rechargeable nickel-cadmium batteries (such as
Cat. No. 23-325) and recharge them in the radio us-
ing an optional AC adapter (such as Cat. No. 273-
1663).
Follow these steps to install batteries.
ALKALINE/
Ni-Cd
1. Turn the radio off, remove the screw from the
belt clip, then slide off the battery compartment
cover.

2. Set the switch inside the compartment to ALKA-
LINE (for alkaline batteries) or Ni-Cd (for
rechargeable nickel-cadmium batteries).
Caution: Do not use alkaline batteries with the
switch set to Ni-Cd.
3. Install the batteries, matching the polarity sym-
bols (+ and –) inside the compartment.
4. Replace the cover.
Caution: Do not mix old and new batteries, different
types of batteries (standard, alkaline, or recharge-
able), or rechargeable batteries of different capaci-
ties.
The radio’s range decreases as the battery power
decreases. To ensure maximum range, keep fresh
batteries in the radio.
When the TX/LO BATT (Transmit/Low Battery) indi-
cator flashes when you are not holding down PTT or
pressing CALL, replace the batteries.

Recharging Nickel-Cadmium Batteries
If you use rechargeable nickel-cadmium batteries,
you can recharge them in the radio using an option-
al AC adapter (such as Cat. No. 273-1663). Be sure
the switch inside the battery compartment is set to
Ni-Cd.
Caution: You must use an AC adapter that supplies
6 volts DC and delivers at least 700 mA. Its center
tip must be set to positive and its plug must fit the ra-
dio’s CHRG jack. The recommended adapter meets
these specifications. Using an adapter that does not
meet these specifications could damage the radio or
the adapter.
1. Attach the adapter’s 3.4 mm outer diameter/1.3
mm inner diameter barrel plug to the adapter
and set TIP to positive (+).

2. Connect the charger’s barrel plug to the radio’s
CHRG jack and plug its other end into a standard
AC outlet
3. Complete charging takes about 15 hours. When
charging is complete, unplug the AC adapter
from the AC outlet and disconnect it from the
.

FCC INFORMATION
Important:
Do not open your radio to make any in-
ternal adjustments. Your radio is set up to transmit a
regulated signal on an assigned frequency. It is
against the law to alter or adjust the settings inside
the radio to exceed those limitations. Any adjust-
ments made to your radio must be made by a quali-
fied technician using the proper test equipment. To
be safe and sure:
• Never open your radio’s case.
• Never change or replace anything in your radio
except the batteries.
Your radio might cause TV or radio interference even
when it is operating properly. To determine whether
your radio is causing the interference, 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
Using your radio as described in this manual ex-
poses you to RF energy well below the FCC’s recom-
mended limits.

rent; (b) any repairs other than those provided by a RadioShack Authorized Service Facility;
(c) consumables such as fuses or batteries; (d) cosmetic damage; (e) transportation, shipping
