GENERAL

INTRODUCTION

SCOPE OF THIS MANUAL

This manual is intended for use by experienced techni-

cians familiar with similar types of commercial grade com-

munications equipment. It contains all required service in-

formation for the equipment and is current as of the publica-

tion date. Changes which may occur after publication are

covered by either Service Bulletins or Manual Revisions,

which are issued as required.

ORDERING REPLACEMENT PARTS

When ordering replacement parts or equipment informa-

tion, the full part identification number should be included.

This applies to all parts : components, kits, and chassis. If

the part number is not known, include the chassis or kit

number of which it is a part, and a sufficient description of

the required component for proper identification.

PERSONNEL SAFETY

The following precautions are recommended for person-

nel safety :

· DO NOT transmit if someone is within two feet (0.6

meter) of the antenna.

· DO NOT transmit until all RF connectors are secure and

any open connectors are properly terminated.

· SHUT OFF and DO NOT operate this equipment near

electrical blasting caps or in an explosive atmosphere.

· All equipment should be properly grounded before

power-up for safe operation.

· This equipment should be serviced by only qualified

technicians.

PRE-INSTALLATION CONSIDERNATIONS

1. UNPACKING

Unpack the radio from its shipping container and check

for accessory items. If any item is missing, please contact

KENWOOD immediately.

2. LICENSING REQUIREMENTS

Federal regulations require a station license for each ra-

dio installation (mobile or base) be obtained by the equip-

ment owner. The licensee is responsible for ensuring trans-

mitter power, frequency, and deviation are within the limits

permitted by the station license.

Transmitter adjustments may be performed only by a li-

censed technician holding an FCC first, second or general

class commercial radiotelephone operator's license. There

is no license required to install or operate the radio.

3. PRE-INSTALLATION CHECKOUT

3-1. Introduction

Each radio is adjusted and tested before shipment. How-

ever, it is recommended that receiver and transmitter op-

eration be checked for proper operation before installation.

3-2. Testing

The radio should be tested complete with all cabling and

accessories as they will be connected in the final installa-

tion. Transmitter frequency, deviation, and power output

should be checked, as should receiver sensitivity, squelch

operation, and audio output. QT equipment operation

should be verified.

4. PLANNING THE INSTALLATION

4-1. General

Inspect the vehicle and determine how and where the

radio antenna and accessories will be mounted.

Plan cable runs for protection against pinching or crush-

ing wiring, and radio installation to prevent overheating.

4-2. Antenna

The favored location for an antenna is in the center of a

large, flat conductive area, usually at the roof center. The

trunk lid is preferred, bond the trunk lid and vehicle chassis

using ground straps to ensure the lid is at chassis ground.

4-3. Radio

The universal mount bracket allows the radio to be

mounted in a variety of ways. Be sure the mounting surface

is adequate to support the radio's weight. Allow sufficient

space around the radio for air cooling. Position the radio

close enough to the vehicle operator to permit easy access

to the controls when driving.

4-4. DC Power and wiring

1. This radio may be installed in negative ground electrical

systems only. Reverse polarity will cause the cable fuse

to blow. Check the vehicle ground polarity before installa-

tion to prevent wasted time and effort.

2. Connect the positive power lead directly to the vehicle

battery positive terminal. Connecting the Positive lead to

any other positive voltage source in the vehicle is not rec-

ommended.

CAUTION

If DC power is to be controlled by the vehicle ignition

switch, a switching relay should be used to switch the posi-

tive power lead. The vehicle ignition switch then controls

DC to the relay coil.

3. Connect the ground lead directly to the battery negative

terminal.

4. The cable provided with the radio is sufficient to handle

the maximum radio current demand. If the cable must be

extended, be sure the additional wire is sufficient for the

current to be carried and length of the added lead.

5. INSTALLATION PLANNING CONTROL STATIONS

5-1. Antenna system

Control station. The antenna system selection depends

on many factors and is beyond the scope of this manual.

Your KENWOOD dealer can help you select an antenna sys-

tem that will best serve your particular needs.

5-2. Radio location

Select a convenient location for your control station radio

which is as close as practical to the antenna cable entry

point. Secondly, use your system's power supply (which

supplies the voltage and current required for your system).

Make sure sufficient air can flow around the radio and power

supply to allow adequate cooling.

SERVICE

This radio is designed for easy servicing. Refer to the

schematic diagrams, printed circuit board views, and align-

ment procedures contained in this manual.

Note

When you modify your radio as described in system set-

up, take the following precaution.

The rating of pin 7 (SB) of the accessory connector cable

(KCT-19) on the rear of the radio is 13.6V (1A). Insert a 1A

fuse if you use the SB pin for external equipment.

Accessory connector

cable (KCT-19)

If you do not intend to use the 3.5-mm jack for the exter-

nal speaker, fit the supplied speaker-jack cap (B09-0235-05)

to stop dust and sand getting in.
