INTRODUCTION

SCOPE OF THIS MANUAL

This manual is intended for use by experienced techni-

cians familiar with similar types of commercial grade commu-

nications equipment. It contains all required service informa-

tion for the equipment and is current as of this publication

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 this equipment when near electrical blasting

caps or while in an explosive atmosphere.

· All equipment should be properly grounded before power-

up for safe operation.

· This equipment should be serviced by only qualified tech-

nicians.

PRE-INSTALLATION CONSIDERATIONS

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 radio

installation (mobile or base) be obtained by the equipment

owner. The licensee is responsible for ensuring transmitter

power, frequency, and deviation are within the limits permit-

ted 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 opera-

tion 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 installation.

Transmitter frequency, deviation, and power output should

be checked, as should receiver sensitivity, squelch operation,

and audio output. Signalling equipment operation should be

verified.

4. PLANNING THE INSTALLATION

4-1. General

Inspect the vehicle and determine how and where the ra-

dio antenna and accessories will be mounted.

Plan cable runs for protection against pinching or crushing

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 installation

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.

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.

GENERAL

TK-8102H

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 system

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.

· Scan ON/OFF

· Talk Around

· Temporary Delete

· None

· AUX

· Horn Alert

· Scan + Temporary Delete

· Emergency

Pressing this key for longer than 1 second causes the

transceiver to enter the emergency mode. The transceiver

jumps to the programmed "Emergency channel" and trans-

mits for 25* seconds.

The transceiver disables mic mute while transmitting. Af-

ter finishing transmission, the transceiver receivers for 5*

seconds. The transceiver Mute* the speaker while receiving.

Following the above sequence, the transceiver continues to

transmit and receive.

* Default value.

· Key lock

Pressing this key causes the transceiver to accept entry of

only the [Vol Up/Down]*, [Key lock], Microphone [PTT],

[Monitor], [Emergency], and [Power] keys.

* Programmable

· Monitor

Used to release signalling (press once) or squelch (press

and hold for approximately two seconds) when operating as a

conventional. It is also used to reset option signalling.

· Scan ON/OFF

Press this key starts scanning. Pressing this key stops

scanning.

· Talk around

Press this key, the transceiver uses the receive frequency

and the tone for transmission.

The operator can call the other party directly (without re-

peater). Press this key again, the talk around function goes

off.

· Temporary delete

The "Add" channel contained in the scan sequence, and

"Delete" channel is not contained. In the scan mode, this

key switches the channel delete temporarily (Press and hold

for approximately one second).

When the transceiver is turned off, the transceiver exits

the scan or switches the scan function off.

· None

Sounds error operation beep, and no action will occur.

Use this function when the transceiver is required to be more

simple operated.

· AUX

Press to activate the auxiliary port. Press again to deacti-

vate the auxiliary port. Auxiliary is used with optional boards,

allowing you to activate and deactivate these optional func-

tions. While activated, the AUX icon appears on the display.

· Horn alert

Horn Alert is a useful feature that will notify you of a re-

ceived call while you are away from your vehicle. The trans-

ceiver is programmed to sound the vehicle horn or some

other external alert device (such as the vehicle headlights)

when a call is received that has correct signalling.

· Scan + Temporarily delete

To temporarily remove a channel from the Scan list, press

and hold this key for approximately one second during Scan,

while Scan is paused on the undesired channel, to tempo-

rarily remove that channel from the scanning sequence. Af-

ter switching the Scan function OFF, or switching the trans-

ceiver OFF and then ON again, the Scan settings return to

normal
