PREPARATION

WARNING

Various electronic equipment in your vehicle may malfunction if they are not properly protected
from the radio frequency energy which is present while transmitting. Typical examples include
electronic fuel injection, anti-skid braking, and cruise control. If your vehicle contains such
equipment, consult the dealer for the make of vehicle and enlist his/her aid in determining if they
will perform normally while transmitting.

Connecting the power cable

CAUTION

The transceiver operates in 12 V negative ground systems only! Check the battery polarity and
voltage of the vehicle before installing the transceiver.

1 Check for an existing hole, conveniently located in the firewall, where the

power cable can be passed through.

• If no hole exists, use a circle cutter to drill a hole, then install a rubber
grommet.

2 Run the power cable through the firewall and into the engine compartment.

3 Connect the red lead to the positive (+) battery terminal and the black lead to

the negative (–) battery terminal.

• Place the fuse as close to the battery as possible.

4 Coil the surplus cable and secure it with a retaining band.

• Be sure to leave enough slack in the cables so the transceiver can be
removed for servicing while keeping the power applied.

Installing the Transceiver

WARNING

For passenger safety, install the transceiver securely using the supplied mounting bracket and
screw set so the transceiver will not break loose in the event of a collision.

Note:

◆ Before installing the transceiver, check how far the mounting screws will extend below
the surface. When drilling mounting holes, be careful not to damage vehicle wiring or
parts.

1 Mark the position of the holes in the dash, using the mounting bracket as a

template. Using a 4.2 mm (5/32 inch) drill bit, drill the holes, then attach the
mounting bracket using the supplied screws.

• Mount the transceiver within easy reach of the user and where there is

sufficient space at the rear of the transceiver for cable connections.

2 Connect the antenna and the supplied power cable to the transceiver.

4

3 Slide the transceiver into the mounting bracket and secure it using the supplied

hex-headed screws.

4 Mount the microphone hanger in a location where it will be within easy reach

of the user.

• The microphone and microphone cable should be mounted in a place

where they will not interfere with the safe operation of the vehicle.

CAUTION

When replacing the fuse in the DC power cable, be sure to replace it with a fuse of the same value.
Never replace a fuse with one that is rated with a higher value.
