CONNECTING POWER
You can power this CB from your ve-
hicle’s battery or from standard AC
power with an optional DC power
supply (such as Cat. No. 22-120).
Using Vehicle Battery Power
1. Connect the CB’s red wire, with
in-line fuse, to a source of volt-
age that turns on and off with the
ignition switch, such as a spare
accessory terminal in your vehi-
cle’s fuse box.
2. Connect the CB’s orange wire,
with in-line fuse, to a source of
voltage that supplies constant
positive (+) power, or directly to
your vehicle’s positive (+) bat-
tery terminal. This connection is
for memory back-up.
3. Connect the CB’s black wire to
your vehicle battery’s negative
(
–
) terminal, or a metal part of
the vehicle’s frame that is not
insulated from the frame by a
plastic part
Using the CB as a
Base Station
Caution: Most 12-volt DC power
supplies plug into a standard AC out-
let to produce DC power. Before con-
necting your CB to a 12-volt DC
power supply, read and follow the in-
structions provided with the power
supply.
1. Connect the CB’s red and
orange wires, each with in-line
fuses, to the DC power supply’s
positive (+) terminal.
2. Connect the CB’s black wire to
the DC power supply’s negative
(
–
) terminal.
3. Plug the power supply’s cord
into a standard AC outlet.
