Setup
Using Vehicle Battery Power
To connect the transceiver to the vehicle battery power:
1. Connect the red wire (with the inline fuse holder) on the back of the
transceiver to a point in your vehicle’s fuse
block that has power only when the ignition is
in the ACC (accessory) or ON position.
2. Connect the black wire to a metal part of the
vehicle’s frame (chassis ground).
Caution: Do not connect the black wire to a
non-metallic (plastic) part, or to any part
insulated from the vehicle’s chassis by a non-
metallic part.
Using the Transceiver
Although this transceiver is designed mainly for mobile use, you can also use
it as a base station with an AC power source. For base station installation, you
need these items (not supplied):
a 13.8V DC power supply that can supply at least 1.5 amps
base station antenna
coaxial antenna cable and connector
Warning: Use extreme caution when you install or remove a base station CB
antenna. If the antenna starts to fall, let it go! It could contact overhead power
lines. If the antenna touches a power line, contact with the antenna, mast, cable,
or guy wires can cause electrocution and death. Call the power company to
remove the antenna. Do not attempt to do so yourself!
Follow these steps to install the CB as a base station.
1. Mount the base station antenna as described in its owner’s manual.
2. Connect the antenna to the ANTENNA jack on the back of the CB.
3. Connect the transceiver’s black power wire to the negative (–) terminal on
the DC power supply.
4. Connect the transceiver’s red wire to the positive (+) terminal on the DC
power supply.
5. Connect the DC power supply to a standard AC outlet.
Caution: Most 13.8V DC power supplies plug into a standard AC outlet to
produce DC power. Before connecting your CB to a 13.8V DC power supply,
read and follow the instructions included with the power supply.
