CONNECTING POWER
You can power your CB from either
standard 120-volt AC or from a 12-
volt DC source, such as a storage
battery.
Using Standard 120-Volt AC
Power
When you use a standard 120-volt
AC power source, set the power se-
lect switch on the back of the CB to
120V AC
.
Then plug the CB's AC power cord
into a standard AC outlet.
Note: The plug is polarized (one
blade is bigger than the other) so it
only fits one way. If it will not fit, turn
it over and try again. Do not force it.
Using 12-Volt DC Power
If you want to use your CB where
120-volt AC power is not available
(for example, when AC power fails or
at a remote location), you can power
your CB from 12-volt DC power. Use
the supplied DC power lead (with in-
line fuse).
Follow these steps to connect the CB
to 12-volt DC power.
1. Connect the plug end of the DC
power leads to the
13.8V DC
power jack on the back of the
CB.
2. Set the power select switch on
the back of the CB to
13.8V DC
.
3. Connect the red and black
power leads to the DC power
source as follows:
• Connect the red lead (with in-
line fuse holder and fuse) to
the source’s (+) terminal.
• Connect the black lead to the
source’s negative (–) terminal.
