PREPARATION

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

Note: The following preparation instructions are for use by your KENWOOD dealer, an authorized
KENWOOD service facility, or the factory.

TOOLS REQUIRED

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

The following tools are required for installing the transceiver:

•6 mm (1/4 inch) or larger electric drill

• Drill bits (sizes listed below) and circle cutters

)hcni23/5(mm2.4swercsgnippat-flesmm61x5

)hcni8/1(mm2.3swercsgnippat-flesmm61x4

POWER CABLE CONNECTION

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 the firewall, then install a rubber
grommet.

2 Run the two power cable leads through the firewall and into the engine

compartment, from the passenger compartment.

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

the negative (–) battery terminal.

• Locate the fuse as close to the battery as possible.

4 Coil and secure the surplus cable with the provided 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

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

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

template. Drill the holes, then attach the mounting bracket using the supplied
5 x 16 mm screws.

• Be sure to mount the transceiver in a location where the controls are 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.

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

supplied hex-headed screws.

4 Mount the microphone hanger, using the supplied 4 x 16 mm screws, 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.

5 Connect one plug of the microphone cable to the jack on the base of the

micropohone, and the other plug to the microphone jack on the front panel of
the transceiver. Place the microphone on the hanger.
