You can attach the microphone holder to either side of the 
CB, horizontally or vertically as shown.

To attach the microphone holder somewhere else, follow 
these steps.

1. Use the microphone holder as a template to mark the 

positions for the screws at the desired location.

2. At the marked positions, drill a hole slightly smaller than 

the mounting screws. Do not drill into anything behind 
the mounting surface.

3. Attach the microphone holder using the supplied 

machine screws and lockwashers.

THE

 CB

Find a convenient location in your vehicle to mount your CB. 
If you are uncomfortable mounting the CB yourself, we 
suggest you consult with 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.

Mount the CB securely to avoid 
damage to the CB or vehicle, and to 
avoid injury to anyone in the vehicle 
during sudden starts or stops.
