THANK YOU

We are grateful you have chosen KENWOOD for your personal mobile applications.

This instruction manual covers only the basic operations of your mobile radio. Ask your dealer for information on any customized features they may have added to your radio.

NOTICES TO THE USER

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

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

◆ Refer service to qualiﬁ 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 modiﬁ cations to this equipment may cause harmful interference unless the modiﬁ cations are expressly approved in the instruction manual.

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 ﬁ re, personal injury, and transceiver damage.

• Do not attempt to conﬁ 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 KENWOOD dealer.

• Use of the transceiver while you are driving may be against trafﬁ c laws. Please check and observe the vehicle regulations in your area.

• Do not use options not speciﬁ ed by KENWOOD.

◆ 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 the supplied DC power cable or a KENWOOD optional DC power cable.

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

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.

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. 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.

■ 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 ﬁ rewall, 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 ﬁ rewall 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

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 sufﬁ cient 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 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.

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.
