noTices To The user

◆ Government law prohibits the operation of unlicensed transmitters within the territories under
government control.

◆ Illegal operation is punishable by ne and/or imprisonment.

◆ Refer service to qualied technicians only.

SAFETY: It is important that the operator is aware of, and understands, hazards
common to the operation of any transceiver.

◆ EXPLOSIVE ATMOSPHERES (GASES, DUST, FUMES, etc.)

Turn OFF your transceiver while taking on fuel or while parked in gasoline service stations. Do not carry

spare fuel containers in the trunk of your vehicle if your transceiver is mounted in the trunk area.

◆ INJURY FROM RADIO FREQUENCY TRANSMISSIONS

Do not operate your transceiver when somebody is either standing near to or touching the

antenna, to avoid the possibility of radio frequency burns or related physical injury.

◆ DYNAMITE BLASTING CAPS

Operating the transceiver within 500 feet (150 m) of dynamite blasting caps may cause them

to explode. Turn OFF your transceiver when in an area where blasting is in progress, or where
“TURN OFF TWO-WAY RADIO” signs have been posted. If you are transporting blasting caps
in your vehicle, make sure they are carried in a closed metal box with a padded interior. Do not
transmit while the caps are being placed into or removed from the container.

One or more of the following statements may be applicable:

FCC WARNING

This equipment generates or uses radio frequency energy. Changes or modications to this
equipment may cause harmful interference unless the modications are expressly approved in the

instruction manual. The user could lose the authority to operate this equipment if an unauthorized

change or modication is made.

INFORMATION TO THE DIGITAL DEVICE USER REQUIRED BY THE FCC

This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation.

This equipment generates, uses and can generate radio frequency energy and, if not installed and
used in accordance with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that the interference will not occur in a particular installation. If
this equipment does cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and receiver.

• Connect the equipment to an outlet on a circuit different from that to which the receiver is

connected.

• Consult the dealer for technical assistance.

PrecauTions

Observe the following precautions to prevent re, personal injury, and transceiver

damage.

• Do not attempt to congure the transceiver while driving; it is too dangerous.

• Do not disassemble or modify the transceiver for any reason.

• Do not expose the transceiver to long periods of direct sunlight, nor place it near heating
appliances.

• If an abnormal odor or smoke is detected coming from the transceiver, switch the
transceiver power off immediately, and contact your

• Use of the transceiver while you are driving may be against trafc laws. Please check

and observe the vehicle regulations in your area.

• Do not use options not specied by

Kenwood.

Kenwood dealer.

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

◆ Use only a Kenwood optional DC power cable.

◆ Do not cut and/or remove the fuse holder on the DC power cable.

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, anti­skid 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 they 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:

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

• 5/32 inch (4.2 mm) drill bit for the self-tapping screws used to mount the optional
mounting bracket

•

Circle cutters

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.

◆ Use only a Kenwood optional DC power cable.

◆ Do not cut and/or remove the fuse holder on the DC power cable.

1 Check for an existing hole, conveniently located in the rewall, where a power

cable can be passed through. If no hole exists, use a circle cutter to drill the

rewall, then install a rubber grommet.

2 Run the two power cable leads through the rewall 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 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.

2

InstallIng the transceIver

For passenger safety, install the transceiver securely using an optional mounting bracket and screw
set 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 self-tapping
screws.

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

reach of the user and where there is sufcient space at the rear of the transceiver for

cable connections.

2 Connect the antenna and power cable to the transceiver.
3 Slide the transceiver into the mounting bracket and secure it using

hex-headed screws.

4 Mount a 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 location where it will
not interfere with the safe operation of the vehicle.

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 a fuse that has a higher value.
