mark the positions for the mounting screws
at the desired mounting location.
2. Drill a hole at the marked position. Do not
drill into anything behind the mounting
surface.
3. Attach the microphone holder to the
mounting surface using the supplied (small)
machine screws and lockwashers.

Mount the CB
Find a convenient location in your vehicle to mount your CB. If you are
uncomfortable mounting the CB yourself, consult your vehicle service
center or automotive dealer for assistance.

Select a mounting location where:
•
you can easily reach the CB.
•
wires and cables are clear of the vehicle’s pedals or other moving
parts.
•
the CB is not directly in front of heating vents.
•
all wires and cables can reach their connection points.
1. Use the mounting bracket as a template to mark the positions for the
screws on the mounting surface.
2. At the marked positions, drill a hole slightly smaller than the mounting
screws. Do not drill into objects behind the mounting surface.
3. Secure the mounting bracket to the mounting surface with the
supplied screws and lockwashers.
4. Attach the CB to the mounting bracket with the supplied rubber
washers and mounting knobs.

2. Connect the cable’s black wire to your vehicle’s negative
battery terminal (–), or to a metal part of the vehicle’s

voltage that turns on and off with the ignition switch, such
as a spare accessory terminal in your vehicle’s fuse box.
This assures you that the CB is turned off when you turn

Connect an Antenna
There are many different types of antennas for mobile CBs.
Each type has its own benefits, so choose the one that best
meets your needs. Your local RadioShack sells a wide variety
of antennas. When choosing an antenna, keep in mind that for
the best performance you should mount the antenna:
•
as high as possible in the vehicle.
•
as far as possible from sources of electrical noise.
•
vertically.
1. Follow the antenna’s mounting instructions.
2. Route the antenna cable to the CB radio and connect it to
the
