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 fine and/or imprisonment.

Refer service to qualified 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

PRECAUTIONS

Observe the following precautions to prevent fire, personal injury, and transceiver damage.

•Do not attempt to configure 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 traffic laws. Please check and observe the vehicle regulations in your area.

•Do not use options not specified 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.

1Check 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.

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

3Connect 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.

4Coil 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.

1Mark 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.

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

3Slide the transceiver into the mounting bracket and secure it using the supplied hex-headed screws.

4Mount 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.

BASIC OPERATIONS

SWITCHING POWER ON/ OFF

Press to switch the transceiver ON.

•A beep sounds and the display illuminates.

•If the Transceiver Password function is programmed, “PS” will appear on the display when the power is turned ON. Refer to “Transceiver Password”, below.

Pressagain to switch the transceiver OFF.

■ Transceiver Password

To enter the password:

1 Press / to select a digit.

•When using an optional microphone with a keypad, simply enter the password digits and proceed to step 3.

2Press C> to accept the entered digit and move to the next digit.

•Press A or # to delete an incorrect digit. Press and hold A or # to delete all digits.

•Repeat steps 1 and 2 to enter the entire password.

3Press S or to confirm the password.

•If you enter an incorrect password, the transceiver remains locked.

ADJUSTING THE VOLUME

Press the [Volume Up] key to increase the volume. Press the [Volume Down] key to decrease the volume.

If Squelch Off has been programmed onto a key, you can use that function to listen to background noise while adjusting the volume level.

SELECTING A ZONE AND CHANNEL

Select the desired zone and channel using the keys programmed as [Zone Up]/

[Zone Down] and [Channel Up]/ [Channel Down].

•“G1” (Zone 1)/ “16” (Channel 16) appears on the display.

TRANSMITTING

1Select your desired zone and channel.

2Press the key programmed as [Monitor] or [Squelch Off] to check whether or not the channel is free.

•If the channel is busy, wait until it becomes free.

3Press the PTT switch and speak into the microphone to transmit. Release the PTT switch to receive.

•For best sound quality at the receiving station, hold the microphone approximately 1.5 inches (3 cm ~ 4 cm) from your mouth.

RECEIVING

Select the desired zone and channel. If signaling has been programmed on the selected channel, you will hear a call only if the received signal matches your transceiver settings.

Note: Signaling allows your transceiver to code your calls. This will prevent you from listening to unwanted calls. Refer to “SIGNALING” on page 10 for details.
