Charging Nickel-Cadmium Batteries 

The walkie-talkie's CHARGER jack is designed for use with Radio Shack's
walkie-talkie nickel-cadmium battery charger (Cat. No. 210-0516).

Cautions:

*  Use only Radio Shack's battery charger (Cat. No. 210-0516) with the
   walkie-talkie's CHARGER jack.  Using a different charger to charge the
   nickel-cadmium batteries might damage your walkie-talkie.

*  Do not connect the battery charger to the walkie-talkie's POWER jack.
   Doing so might damage the charger.

*  Do not connect  anything to the CHARGER jack when you have installed
   non-rechargeable batteries.  Doing so might damage your walkie-talkie.

New nickel-cadmium batteries come fully discharged.  To charge nickel
cadmium batteries, turn off the walkie-talkie's power and connect the
charger to the CHARGER jack.  It takes 16 to 18 hours to charge fully
discharged batteries.  You cannot operate the walkie-talkie while you
charge batteries.

Warning:  Never try to recharge non-rechargeable batteries.  They become
very hot and might explode.

Charging Hint:

Nickel-cadmium batteries last longer and deliver more power if you
occasionally let them discharge completely.  To do so, simply use the
walkie-talkie until the BATT indicator lights.  Then, fully recharge the
batteries.  If you do not let nickel-cadmium batteries discharge, they
lose the ability to use their full power capacity.

Using AC Power

You can power the walkie-talkie from AC power using an optional 12-volt
power supply (Cat. No. 220-0120).

Caution:  Using a different power supply might damage your transceiver or
          the power supply

1.  Make a power cable, using a 3.5 mm power connector plug (available
    at your local Radio Shack store).  Be sure to wire the plug with the
    tip positive.

2.  Connect the leads from the plug to the + and - terminals on the power
    supply.

3.  Turn on the power supply and use a voltmeter to be sure that you have
    correctly wired the plug.  Then, turn off the power supply.

4.  Insert the plug into the walkie-talkie's POWER jack.

Caution:  Do not connect this power supply to the CHARGER jack.  Doing so
          might damage the walkie-talkie.

5.  Turn on the power supply.

6.  When you finish using AC power, turn off the power supply.  Then,
    disconnect the power supply's plug from the POWER jack.

Using Your Vehicle's Battery

You can power your walkie-talkie from your vehicle's cigarette lighter
socket, provided your vehicle has a 12 volt, negative-ground electrical
system.  Use Radio Shack's 12-volt power cord (Cat. No. 270-1533).

Caution:  Using a different power cord might damage the walkie-talkie or
          the power cord.

1.  Insert the cord's barrel plug into the walkie-talkie's POWER jack.

Caution:  Do not insert the plug into the CHARGER jack.  Doing so might
          damage the walkie-talkie.

2.  Plug the other end of the cord into your vehicle's cigarette lighter
    socket.

Note:  If the walkie-talkie does not operate properly when you use the
       lighter cord, unplug the cord from the lighter socket and clean
       the socket to remove ashes and other debris.  If your walkie-
       talkie still does not work, check the fuse in the power cord and
       replace it if necessary.

When you finish using the power cord, disconnect it from the cigarette
lighter socket.  Then, disconnect the cord from your walkie-talkie.

CONNECTING AN ANTENNA

Your walkie-talkie-talkie includes an efficient rubber antenna that is
ideal for most applications.  Simply screw the antenna into the walkie
-talkie's antenna socket.  For Mobile or Base-station applications, you
might want to connect a more efficient external mobile or outdoor base
antenna to your walkie-talkie's ANTENNA jack.  This connection requires a
coaxial plug adapter.  Your local Radio Shack store sells the proper
adapter and a variety of external antennas for your walkie-talkie.

Warning:  When installing or removing base station CB antennas, use
          extreme caution.  If the antenna starts to fall, let it go!
          It might contact overhead power lines.  If the antenna is
          touching a power line, contact with antenna, mast, cable, or
          guy wires can cause electrocution and Death! Call the power
          company to remove the antenna.  Do not attempt to remove it
          yourself.

Caution:  Never try to transmit without an antenna, you might damage the
          walkie-talkie.
