Typical Under-dash installation
Connecting to a Positive Ground System
Follow the instructions in this section only if you are certain that your vehicle has a positive ground
system. Connect the positive (red) wire to a screw or bolt on the metal frame supporting the
instrument panel, or to any metal point that is part of the Vehicle's metal structure. Remove any
paint or coating from under the screw or bolt to ensure good electrical contact.
If you want your radio to operate at all time without having the ignition switch turned on, connect the
negative (black or green) wire to the INTERIOR LAMP terminal on the vehicle's fuse panel. If you
want your radio to operate only when the ignition switch is turned on, connect the negative (black)
wire to the RADIO terminal on the vehicle's fuse panel.
Do not turn on the CB radio until the antenna is connected. If you attempt to transmit without the
antenna connected, you risk burning out the unit's power transistors.
Antennas
The antenna's mounted location on the vehicle affects the operation of the CB radio. Transmission and
reception characteristics vary for different antenna locations.
Ideally, the transmitted power and receiving sensitivity should be uniform in all directions, regardless of
which direction the vehicle faces.
In a typical installation however, the vehicle's irregular shape produces some cancellation effects which
prevent ideal performance. However, an antenna located near the center of the vehicle's roof will provide
performance closest to ideal. A compromise between such factors as the cost of the antenna, the ease and
personal preference of installation, and uniformity of the desired transmission/reception characteristics will
determine the best mounting location.
