Note
Before installing the CB radio,
visually check the vehicle’s
battery connection to deter-
mine which terminal, positive
or negative, is grounded (pos-
itive is the larger of the two)
to the engine block (or chas-
sis). A negatively grounded
vehicle has its negative lead
grounded to the chassis.
Note
Connecting to an accessory fuse
prevents the unit from being left
on accidentally, and also per-
mits operating the unit without
running the engine.
Note
In positive ground vehicles the
red wire goes to the chassis and
the black wire is connected to
the ignition switch.
Note
When connected to an accesso-
ry fuse, unit will self test the
emergency weather alert auto-
matically when ignition is
turned on. Turns itself on & off.
In a negative grounded vehicle, connect the
red lead of the DC power cord to an accessory
12 volt fuse.
Connect the black lead to the negative side of
the vehicle. This is usually the chassis. Any con-
venient location with a good electrical contact
(remove paint) may be used.
