Note

Connecting to an accessory
fuse prevents the unit from
being left on accidentally, and
also permits 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

Before installing the CB radio,
visually check the vehicle’s
battery connection to
determine which terminal,
positive or negative, is
grounded (positive is the
larger of the two) to the
engine block (or chassis).
A negatively grounded
vehicle has its negative lead
grounded to the chassis.

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
convenient location with a good electrical
contact (remove paint) may be used.

Plug power cable into back of unit marked

Mount the microphone
bracket on either side
of the unit (driver’s left)
using two screws
supplied. Bracket should
be placed under the dash
so microphone is readily
accessible.
