INSTALLATION

MOUNTING THE 
MICROPHONE HOLDER

Using a Phillips screwdriver and the
supplied screws and washers, attach
the supplied microphone holder to the
CB’s left or right side either horizontally
or vertically.

MOUNTING THE TRC-445

The most common mounting location for
this CB is under a vehicle’s dashboard.
However, if you use the TRC-445 as a
base station, you can place it on a desk,
shelf, or table (see “Using the CB as a
Base Station” on Page 8).

If you are mounting the CB in a vehicle,
choose a 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.

Cautions:

• If you use the TRC-445 in a vehicle,

mount it securely to avoid damage
to the CB or vehicle or injury to any-
one in the vehicle during sudden
starts or stops.

• Do not mount the CB where it could

damage or interfere with the proper
operation of any passive restraint
safety device (an air bag or seat
belt).

Follow these steps to mount the CB us-
ing the supplied hardware.

1. Using the slots in the mounting

bracket as a template, mark the
positions for the screw holes.

2. In each marked location, drill a hole

slightly smaller than the supplied
mounting screws.

Caution: Be careful not to drill into
anything behind the mounting sur-
face.

3. Using a Phillips screwdriver, attach

the mounting bracket to the mount-
ing surface with the large mounting
screws and star lock washers.
