INTRODUCTION

SCOPE OF THIS MANUAL

This manual is intended for use by experienced technicians familiar with similar types of commercial grade communications equipment. It contains all required service information for the equipment and is current as of the publication date. Changes which may occur after publication are covered by either Service Bulletins or Manual Revisions. These are issued as required.

ORDERING REPLACEMENT PARTS

When ordering replacement parts or equipment information, the full part identification number should be included. This applies to all parts : components, kits, or 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 personnel safety :

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

meter) of the antenna.

• DO NOT transmit until all RF connectors are verified se-

cure 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 a qualified techni-

cian only.

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.

GENERAL

TK-860G /(N)/862G/(N

)

2. PRE-INSTALLATION CHECKOUT 2-1. Introduction

Each radio is adjusted and tested before shipment. However, it is recommended that receiver and transmitter operation be checked for proper operation before installation.

2-2. 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.

3. PLANNING THE INSTALLATION 3-1. 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 crushing wiring, and radio installation to prevent overheating.

3-2. 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.

3-3. 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.

3-4. 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.

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.

4. INSTALLATION PLANNING – CONTROL STATIONS 4-1. 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.

4-2. 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 alignment procedures contained in this manual.

Note

When you modify your radio as described in system setup, take the following precaution.

The rating of pin 7 (SB) of the accessory connector cable (KCT-19) on the rear of the radio is 13.2V (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 external speaker, fit the supplied speaker-jack cap (B09-0235-05) to stop dust and sand getting in.

4. Scan Operating (TK-860G only)

■ Scan types

• Single group scan

You can scan all valid (ADD) channels in the displayed group that can be selected with the group up/down key.

• Multiple group scan

You can scan all valid (ADD) channels in the all valid (ADD) group.

■ SCAN start condition

One or more non-priority channels must be added to all channels that can be scanned. The transceiver must be in normal receive mode (PTT off).

When you activate the key programmed to the scan function, the scan starts. The scan icon “SCN” lights and “SCAN” is indicated on alphanumeric display.

■ Scan stop condition

The scan stops temporarily if the following conditions are satisfied.

1) A carrier is detected, then signalling matches on chan-

nels for which receive the signalling is set by the pro-

gramming software.

2) A carrier is detected on the channels for which receiving

signalling is not set by the programming software or

when the monitor (signalling cancel) function is activated.

TK-860G /(N)/862G/(N

OPERATING FEATURES

)

■ Scan channel types

1) Priority channel is the most important channel for the scan, and always detects a signal during scan and when the scan stops temporarily.

2) Non-priority channels detects a signal during scan. For the channels that can be selected with the group or channel up/down key when the scan does not occur, adds an indicator “A” lights.

■ Priority channel setting

A priority channel can be set as follows with the program-

ming software (KPG-67D).

1) Specify a priority channel as a fixed priority channel.

2) Make a selected channel, a priority channel.

■ Scan type according to the priority channel

1) When no priority channel is set : Only the non-priority channels are scanned. If a non-priority channel stops temporarily, it stops until there is no signal on the channel.

2) When priority channel is set : Either priority channel is scanned. If a non-priority channel stops temporarily, a priority channel signal is detected at certain intervals. If a priority channel stops temporarily, it stops until there is no signal on the priority channel.

■ Revert channel

The revert channel is used to transmit during scanning

and set by the programming software (KPG-67D).

1) Priority The transceiver reverts to the priority channel.

2) Priority with talkback The transceiver reverts to the priority channel. If you press PTT during a resume timer (dropout delay time, TX dwell time) or calling, you can transmit on current channel to answer to the call however revert channel is set to priority channel. After resume time, scan re-starts and transmission channel is return to priority channel.

3) Selected channel The transceiver reverts to the channel before scanning or the channel that you changed during scan.

4) Last called channel The transceiver reverts to the last called channel during the scan.

5) Last used channel The transceiver reverts to the last used (transmitted) channel during scan. “Last used” revert channel includes talkback function.

6) Selected with talkback The transceiver reverts to the channel before scanning or the channel that you changed during scan.

■ Scan end

When you reactivate the key programmed to the scan

function during scan mode, the scan ends.

The scan icon “SCN” and “SCAN” display goes off.

■ Temporarily delete/add

It is possible to delete or add channel temporarily during scan. When scan stops on unnecessary channel for example by interference of the other party, activate the delete/ add function (for example press the key), then that channel is deleted temporarily and scan re-start immediately.

When you would like to add the deleted channel temporarily to scan sequence, select the desired (deleted) channel during scan, activate the delete/add function (for example press the key) before scan re-start.

That channel is added temporarily to scan sequence. The temporary deleted or added channels are returns to pre-set delete/add, when the transceiver exits from scan mode.

5. Details of Features

■ Time-out timer

The time-out timer can be programmed in 15 seconds increments from 15 seconds to ten minutes. If the transmitter is keyed continuously for longer than the programmed time, the transmitter is disabled and a warning tone sounds while the PTT button is held down. The alert tone stops when the PTT button is released.

■ PTT ID

PTT ID provides a DTMF ANI to be sent with every time PTT (beginning of transmission, end of transmission, or both).

You can program PTT ID “on” or “off” for each group. The contents of ID are programmed for each channel.

The timing that the transceiver sends ID is programmable.

BOT : DTMF ID (BOT) is sent on beginning of transmis-

sion.

EOT : DTMF ID (EOT) is sent on end of transmission.

Both : DTMF ID (BOT) is sent on beginning of transmis-

sion and DTMF ID (EOT) is sent on end of transmission.

■ Radio password (TK-860G only)

When the password is set in the transceiver, user can not use the transceiver unless enter the correct password.

This code can be up to 6 digits from 0 to 9 and input with the key, and “SCN” key.

■ Off hook decode

If the Off hook decode function has been enabled, removing and replacing the microphone on the hook has no effect for decoding QT/DQT and option signalling.

■ “TOT” pre-alert

The transceiver has “TOT” pre-alert timer. This parameter selects the time at which the transceiver generates “TOT” pre-alert tone before “TOT” is expired.

“TOT” will be expired when the selected time passes from a “TOT” pre-alert tone.

TK -860/G(N)/862G/(N

OPERATING FEATURES

)

■ “TOT” re-key time

The transceiver has “TOT” re-key timer. This timer is the time you can not transmit after “TOT” exceeded. After “TOT” re-key time expired you can transmit again.

■ “TOT” reset time

The transceiver has “TOT” reset timer. This timer is the minimum wait time allowed during a transmission that will reset the “TOT” count.

“TOT” reset time causes the “TOT” to continue even after PTT is released unless the “TOT” reset timer has expired.

■ Clear to transpond

The transceiver waits the transpond of 5-tone/2-tone / DTMF if channel is busy until channel open. This feature prevents the interference to other party.

6. Option Signalling (DTMF/2-Tone)

Built-in DTMF decoder is available for option signalling.

Built-in 2-tone decoder is available for option signalling.

It is possible to use individual call, group call, D.B.D. (Dead Beat Disable). D.B.D. is used with DTMF only.

If the option signalling matches, a predetermined action will occur.

If option signalling matches on a group/channel which is set up with option signalling, the option signalling indicator (CALL) will flash and option signalling will be released. The transpond or alert tone will sound.

The orange LED will flash.

While option signalling matches (or if option signalling is deactivated when you are transmitting), you can mute or unmute QT/DQT/Carrier.

■ Dead Beat Disable

If the D.B.D. code matches, a predetermined action will occur. Whether option signalling is activated or not, when D.B.D. matches on any channel, the transceiver will become TX inhibited or TX/RX inhibited. While D.B.D. is active, if the D.B.D. code + “#” code is received, D.B.D. will disactivate.

When D.B.D. matches, transpond will function. Alert will not be output, and option signalling match icon will not appear.

7. Audible User Feedback Tones

The transceiver outputs various combinations of tones to notify the user of the transceiver operating state. The main tones are listed below.

The high tone is 1477Hz, the mid tone is 941Hz, and the low tone is 770Hz.

■ Power on tone

This tone is output when the transceiver is turned on. (The high tone is output for 500ms.)

■ Alert tone

This tone is output when the transceiver is TX inhibition for TOT, and PLL unlocked. It is output until the PTT button is released.

■ DBD on tone

When a D.B.D. code is received, transpond tone sounds.

■ DBD off tone

When a D.B.D. release code is received, transpond tone sounds.

■ AND/OR

You can select AND or OR for option signalling match

conditions.

Alert/Transpond

AND QT/DQT+DTMF (2-tone); Option matches = Action

OR QT/DQT+DTMF (2-tone); Option matches = Action

AF mute open

AND QT/DQT+DTMF (2-tone); Option matches = Action

OR QT/DQT/ID; Signalling only matches = Action

With OR set up, alert/transpond will not function with

only DTMF.

With OR set up, AF mute will not release when only

DTMF matches.

With a conventional channel not set up with QT or DQT,

only the carrier is considered when signalling matches.

■ Auto Reset

If option signalling matches a group set up with option signalling, option signalling is released. After matching option signalling, option signalling will temporarily reset automatically.

■ Busy tone

Sounds in conventional mode, when busy channel lockout is functioning. You can select yes or no for the optional feature’s warning tone.

■ Group call tone

Sounds when a group call with the correct DTMF/2-tone option signalling is received, repeats 7 times. You can select yes or no for the optional feature’s warning tone.

■ Individual call tone

Sounds when an individual call with the correct DTMF/2tone option signalling is received. You can select yes or no for the optional feature’s warning tone.

■ Key press tone [A]

Sounds when a key is pressed. For toggle keys, sounds when toggle function is turned on (key press tone [B] sounds when it is turned off). You can select yes or no for the optional feature’s control tone.

5. PC Mode

5-1. Preface

The TK-860G/862G transceiver is programmed using a

personal computer, a programming interface (KPG-46) and programming software (KPG-67D).

The programming software can be used with an IBM PC

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

5-2. Connection Procedure

1. Connect the TK-860G/862G to the personal computer with the interface cable.

2. When the Power is switched on, user mode can be entered immediately. When the PC sends a command, the radio enters PC mode. When data is transmitted from transceiver, the red LED blink. When data is received by the transceiver, the green LED blink.

Notes :

• The data stored in the personal computer must match model type when it is written into the flash memory.

• Change the TK-860G/862G to PC mode, then attach the interface cable.

5-3. KPG-46 Description

(PC programming interface cable : Option)

The KPG-46 is required to interface the TK-860G/862G

with the computer. It has a circuit in its D-subconnector (25pin) case that converts the RS-232C logic level to the TTL level.

The KPG-46 connects the modular microphone jack of

the TK-860G/862G to the computers RS-232C serial port.

KPG-46

IBM-PC

5-4. Programming Software KPG-67D Description

The KPG-67D is programming software for the transceiver supplied on two 3.5" floppy disks. This software runs under MS-DOS 3.1 or later on an IBM-PC or compatible machine.

The data can be input to or read from the transceiver and edited on the screen. The programmed or edited data can be printed out. It is also possible to tune the transceiver.

We recommend that install the KPG-67D for example to harddisk first then use it.

6. Firmware Programming Mode

6-1. Preface

Flash memory is mounted on the TK-860G/862G. This allows the TK-860G/862G to be upgraded when new features are released in the future. (For details on how to obtain the firmware, contact Customer Service.)

6-2. Connection Procedure

Connect the TK-860G/862G to the personal computer (IBM PC or compatible) with the interface cable (KPG-46). (Connection is the same as in the PC Mode.)

6-3. Programming

1. Start up the programming software (KPG-67D), select

“firmware program” in the “Program” item, and press

the Return key on your personal computer. This starts up

the firmware programmer.

2. The top screen is displayed. Press any key to advance to

the next screen.

3. Set the communications speed (normally, 57600 bps)

and communications port in the Setup item.

4. Set the firmware to be updated by File select (=F1).

5. Turn the TK-860G/862G Power ON with the [CH

switch held down. Hold the switch down for two sec-

onds until the display changes to “PROG 576”, the

BUSY/TX LED lights orange. When “PROG 576” ap-

pears, release your finger from the switch.

6. Check the connection between the TK-860G/862G and

the personal computer, and make sure that the TK-860G/

862G is in Program mode.

7. Press F10 on the personal computer. A window opens

on the display to indicate the writing progress. When the

TK-860G/862G starts to receive data, the BUSY/TX LED

lights green.

8. If writing ends successfully, the LED on the TK-860G/

862G goes off and the checksum is displayed.

(Since the TK-862G does not have a display, check the

checksum with the FPU (KPG-67D).)

9. If you want to continue programming other TK-860G/

862G, repeat steps 5 to 8.

Notes :

• To start the Firmware Programmer from KPG-67D, the FPRO path must be set up by the KPG-67D setup.

• This mode cannot be entered if the Firmware programming mode is set to Disable in the Programming software (KPG-67D).

• When programming the firmware, it is recommend to copy the data from the floppy disk to your hard disk before you update the radio firmware. Directly copying from the floppy disk to the radio may not work because the access speed is too slow.

6-4. Function

1. If you press the [MON] switch while “PROG 576” is displayed, the checksum is displayed. If you press the [MON] switch again (while the checksum is displayed), “PROG 576” is redisplayed.

2. If you press the [A] switch while “PROG 576” is displayed, the display changes to “PROG 192” to indicate that the write speed is low speed (19200 bps). If you press the [A] switch again while “PROG 192” is displayed, the display changes to “PROG 384”, and the write speed becomes the middle speed (38400 bps). If you press the [A] switch again while “PROG 384” is displayed, the display returns to "PROG 576".

Note :

TK-862G indicate

19200 bps : The LED flashes green and red alternately. 38400 bps : The LED flashes orange. 57600 bps : The LED lights orange.

Normally, write in the high-speed mode.

you press the [SCN] key, the currectly selected number is determined, and the display shifts to the left. If you press the [SCN] key after entering the password in this procedure, “CLONE” is displayed if the entered password is correct. If the password is incorrect, “CLN LOCK” is redisplayed.

4. Power on the slave TK-860G.

5. Connect the cloning cable (No. E30-3382-05) to the modular microphone jacks on the master and slave.

6. Press the [SCN] key on the master while the master displays “CLONE”. The data of the master is sent to the slave. While the slave is receiving the data, “–PC–” is displayed. When cloning of data is completed, the master displays “END”, and the slave automatically operates in the User mode. The slave can then be operated by the same program as the master.

7. The other slave can be continuously cloned. When the [SCN] key on the master is pressed while the master displays “END”, the master displays “CLONE”. Carry out the operation in step 4 to 6.

Note :

You can clone the programmed data between the trans-

ceiver frequency version must be same.

7. Clone Mode (TK-860G only)

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).

1. Turn the master TK-860G power ON with the [

held down. If the password is set to the TK-860G, the

TK-860G displays “CLN LOCK”. If the password is not

set, the TK-860G displays “CLONE”.

2. When “CLN LOCK” is displayed, only the [CH

and [SCN], and [0] to [9] keys can be accepted. When

you enter the correct password, and “CLONE” is dis-

played, the TK-860G can be used as the cloning master.

The following describes how to enter the password.

3. How to enter the password with the microphone keypad;

If you press a key while “CLN LOCK” is displayed, the

number that was pressed is displayed on the TK-860G.

The Horn Alert (max. 2A drive) and Public Address functions are enabled by inserting the KAP-1 W1 (3P; white/ black/red) into CN3 on the TX-RX unit, inserting W2 (3P; green) into CN7 on the TX-RX unit, and connecting the KCT19 (option) to CN2 and CN3 of the KAP-1.

• Installation procedure

1. Open the upper case of the transceiver.

2. Insert the two cables ( ) with connectors from the

KAP-1 switch unit into the connectors on the transceiver.

3. Secure the switch unit board to the chassis with a screw

( ). The notch ( ) in the board must be placed at the

front left side.

4. Attach the cushion on the top of the KAP-1 switch unit.

4-2. Modifying the Transceiver

• Horn alert

The signal from pin 4 of IC9 on the TX-RX unit turns Q5 and Q1 on and off and drives KAP-1 HA relay K2 to drive the horn with a maximum of 2A.

The default output is HR1. The relay open output can be obtained between HR1 and HR2 by removing R1 in the KAP-

R1 Output form

• Public address

The signal from pin 13 of IC9 on the TX-RX unit drives PA relay K1 in the KAP-1 and switches the audio power amplifier output between the external PA system (through KCT-

19) and internal and external speakers.

To use the PA function, R153 on the TX-RX unit must be removed.
