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.

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.

3-1. Preface

The TK-8100H transceiver is programmed using a per-

sonal computer, a programming interface (KPG-46) and pro-

gramming software (KPG-80D).

The programming software can be used with an IBM PC

or compatible. Figure 1 shows the setup of an IBM PC for

programming.

3-2. Connection Procedure

1. Connect the TK-8100H to the personal computer with the

interface cable.

2. When the Power is switched on, user mode can be en-

tered immediately. When the PC sends a command, the

radio enters PC mode.

When data is transmitted from transceiver, the TX indica-

tor blink.

When data is received by the transceiver, the BUSY indi-

cator blink.

In the PC mode, " PC " is displayed on the LCD.

3-3. KPG-46 Description

(PC programming interface cable : Option)

The KPG-46 is required to interface the TK-8100H to the

computer. It has a circuit in its D-subconnector (25-pin) case

that converts the RS-232C logic level to the TTL level.

The KPG-46 connects the modular microphone jack of the

TK-8100H to the computers RS-232C serial port.

3-4. Programming Software Description

KPG-80D is the programming software for TK-8100H sup-

plied on three 3.5" floppy diskettes. This software runs un-

der Windows 98, ME, Windows 2000 or XP on an IBM-PC or

compatible machine.

The data can be input to or read from TK-8100H and edited

on the screen. The programmed or edited data can be

printed out. It is also possible to tune the transceiver.

4. Clone Mode

Programming data can be transferred from one radio to

another by connecting them via their modular microphone

jacks. The operation is as follows (the transmit radio is the

master and the receive radio is the slave).

Note :

Clone mode should be enabled.

1. Turn the master TK-8100H power ON with the [CH

DOWN] key held down (2 seconds), " CLONE " is dis-

played on the LCD.

2. Power on the slave TK-8100H.

3. Connect the cloning cable (No. E30-3382-05) to the modu-

lar microphone jacks on the master and slave.

4. Press the [MON] key on the master TK-8100H transceiver.

The data of the master is sent to the slave. While the

master is sending data, [TX] icon blinked. While the slave

is receiving the data, " PC " is displayed and [BUSY]

icon blinked. When cloning of data is completed, the mas-

ter display "END", and the master [TX] icon turned off,

and the slave automatically operates in the User mode.

The slave can then be operated by the same program as

the master.

5. The other slave can be continuously cloned. Carry out the

operation in step 2 to 4.
