Connecting an Antenna

Once you choose an antenna, follow the

mounting instructions supplied with the

antenna. Route the antenna cable to the

CB, then screw the cable into the

AN-

TENNA

jack on the back of the CB.

Cautions

:

• Do not run the cable over sharp

edges or moving parts that might

damage it.

• Do not run the cable next to power

cables or other CB antenna cables.

• Do not run the cable through a vehi-

cle’s engine compartment or other

areas that produce extreme heat.

USING VEHICLE BATTERY

POWER

You can power this CB from your vehi-

cle’s battery or from standard AC power

with an optional DC power supply. For

information on using AC power, see “Us-

ing the CB as a Base Station.”

Follow these steps to power the CB from

your vehicle’s battery.

1. Plug the single connector end of the

power cord into the

POWER 13.8V

DC

jack on the CB’s back panel.

2. Connect the black wire to your vehi-

cle battery’s negative (–) terminal or

to a metal part of the vehicle’s frame

that is not insulated from the frame

by a plastic part.

3. Connect the red wire, with in-line

fuse, to a source of voltage that

turns on and off with the ignition

switch, such as a spare accessory

terminal in your vehicle’s fuse box.

This prevents the battery from being

drained if you leave the CB on when

you turn off the ignition.

4. Connect the orange wire, with in-line

fuse, to a source of voltage that sup-

plies constant positive (+) power, or

directly to your vehicle’s positive (+)

battery terminal. This enables the

radio to “remember” the last channel

you tuned to when you turn the radio

back on.
