ANTENNA CONNECTION

For best performance:

•Use a properly adjusted, good-quality 50 Ω

antenna.

•Use a good-quality 50 Ωcoaxial cable and

connector.

•Match the impedance of the coaxial cable and

antenna so that the SWR is 1.5:1 or less.

•Ensure that all connections are clean and tight.

The transceiver’s protection circuit will activate if the

SWR is greater than 2.5:1, but do not rely on

protection to compensate for a poorly functioning

antenna system. High SWR will cause the transmit

output to drop, and may lead to radio frequency

interference with consumer products such as stereo

receivers and televisions. You may even interfere

with your own transceiver. Reports that your signal is

garbled or distorted, especially at peak modulation,

may indicate that your antenna system is not

transmitting efficiently.

◆Transmitting without first connecting an antenna or other

matched load may damage the transceiver. Always connect

the antenna to the transceiver before transmitting.

◆Use a lightning arrestor to prevent fire, electric shock, or

damage to the transceiver.

GROUND CONNECTION

•Agood DC ground is required to prevent such

dangers as electric shock.

•Agood RF ground is required for superior

communcations, against which the antenna

system can operate.

Both of these conditions can be met by providing a

good earth ground for your station. Bury one or more

ground rods or a large copper plate under the ground,

and connect this to the transceiver GND terminal.

Use heavy gauge wire or a copper strap, cut as short

as possible, for the connection. Ensure that all

connections are clean and tight.

BASE STATION INSTALLATION

FOOT PADS

A set of foot pads are provided so that you can

protect the surface of your desk/table/shelf from

Base Station Installation

DC POWER SUPPLY CONNECTION

In order to use this transceiver as a base station, you

will need a separate 13.6 V DC power supply with a

current capacity of 20.5 A or higher (purchased

separately).

◆Do not directly connect the transceiver to an AC outlet.

◆Do not substitute the supplied DC power cable with a cable

with smaller gauge wires.

◆Before connecting the DC power supply to the transceiver, be

sure to switch the DC power supply OFF.

◆Do not plug the DC power supply into an AC outlet until you

make all connections.

1Connect the supplied DC power cable to the

regulated DC power supply and check that the

polarities are correct (Red: positive, Black:

negative).

2Connect the connectorized end of the DC power

cable to the DC 13.6 V powerconnector on the

rear of the transceiver.

•Press the DC power cable connector firmly into the

connector on the radiotelephone until the locking tab

clicks.

■REPLACING FUSES

If the fuse blows, determine the cause then correct

the problem. After the problem is resolved, only

then replace the fuse. If newly installed fuses

continue to blow, disconnect the power plug and

contact your dealer for assistance.

Following are the ratings for fuses used with this

transceiver:

Transceiver: 4 A (for KAT-1 antenna tuner)

DC cable: 25 A

◆When replacing any fuse, be sure to replace it with a fuse

of the same value. Never replace a fuse with a fuse that

has a higher value.

◆Replace blown fuses only after investigating and

correcting the cause of the failed fuse.

MOBILE INSTALLATION

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 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.

INSTALLING THE TRANSCEIVER

For passenger safety, install the transceiver securely using an

optional mounting bracket so the transceiver will not break loose

in the event of a collision.

1Mark 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 supplied with the bracket.

•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.

2Connect the antenna and the supplied power

cable to the transceiver {page 3}.

3Slide the transceiver into the mounting bracket

and secure it.

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.

ANTENNA CONNECTION

For best performance:

•Use a properly adjusted, good-quality 50 Ω

antenna.

•Use a good-quality 50 Ωcoaxial cable and

connector.

Coupling the antenna to the transceiver via feed lines

having an impedance other than 50 Ωreduces the

efficiency of the antenna system and can cause

interference to nearby broadcast television receivers,

radio receivers, and other electronic equipment.

Transmitting without first connecting an antenna or other matched

load may damage the transceiver. Always connect the antenna to

the transceiver before transmitting.

GROUND CONNECTION

•Ahigh-quality ground installation significantly

improves the performance of a mobile antenna.

Securely connect a low-resistance ground strap (or

large gauge copper wire if unavailable) from the

transceiver GND terminal to the vehicle chassis.

Clean paint or dirt from the vehicle connection point

to expose bare metal before connecting the ground.

DC 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 the firewall, then install a rubber grommet.

2Run the two power cable leads through the firewall

and into the engine compartment, from the

passenger compartment.

3Connect the red lead to the positive (+) battery

terminal and the black lead to the negative (–)

battery terminal.

•Use the full length of the cable without cutting off any

excess; in particular, never remove the fuse holders.

•To prevent the risk of short circuits, disconnect other

wiring from the negative (–) battery terminal before

connecting the transceiver. Reconnect the wiring

after connecting the transceiver to the battery.

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

4Coil 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.

•Ensure that the cable is isolated from heat and

moisture. If necessary, wrap heat-resistant tape

around the fuse holder to protect it from moisture.

•If using a noise filter, it should be installed with an

insulator to prevent it from touching metal on the

vehicle.

5Connect the DC power cable to the rear of the

transceiver.

•Press the connectors firmly together until the locking

tab clicks.

Note:

◆We do not recommend using the cigarette lighter socket, as

some cigarette lighter sockets introduce an unacceptable

voltage drop.

◆If you use the transceiver for a long period when the vehicle

battery is not fully charged or when the engine is OFF, the

battery may become discharged and will not have sufficient

reserves to start the vehicle. Avoid using the transceiver

under these conditions.

■REPLACING FUSES

If the fuse blows, determine the cause then correct

the problem. After the problem is resolved, only

then replace the fuse. If newly installed fuses

continue to blow, disconnect the power plug and

contact your dealer for assistance.

Following are the ratings for fuses used with this

transceiver:
