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, which 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, 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 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 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 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 permitted by the station license.

Transmitter adjustments may be performed only by a licensed 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. However, it is recommended that receiver and transmitter operation 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. 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 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 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 positive 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.

GENERAL / OPERATING FEATURES

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 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 13.6V (1A). Insert a 1A fuse if you use the SB pin for external equipment.

OPERATING FEATURES

3. Scan Operating

■ System Scan

System scan can be selected with the “Scan” key by programming the scan feature. When the “Scan” key is pressed and the “SCN” mark appears, scan mode in entered. Scanning starts from the system following the currently displayed system. When a call is received, scanning stops, and the system and group are displayed.

When programming key is touched during scanning, the scan stops and the revert system or group can be changed. Scanning resumes one second after the key is released.

There are two types of system scan.

• Fix System Scan

All the set systems except locked-out ones are scanned. If the Del/Add feature is assigned to the programmable key, it can be controlled from the front panel.

• List Type System Scan

A scan list can be set for each system.

The list to be scanned can be changed by changing the display system.

If many systems have been set, the scan speed can be increased by narrowing the systems to be scanned with scan lists.

■ System Lockout

The system lockout feature is used to lock systems out of the scan sequence, and can be selected by programming in the following two ways;

• Fixed Lockout

The system to be locked out is selected by programming. When a locked system is selected, the Delete ( appears on the left of the SYSTEM indicator. The revert system is scanned even if it is locked out. If there is a locked system, the Delete ( ning.

) indicator flashes during fixed scan-

• User Selectable Lockout

If the scan lockout feature is programmed to a key, the user can lock systems out of the scan sequence with the key. To lock a system out of the scan sequence, press the key when the system is displayed. The Delete ( is displayed on the left of the SYSTEM indicator.

To unlock a system, select the system and press the key. The Delete ( tem has returned to the scan sequence. The revert system is scanned even if it is locked out. If there a locked system, the Delete ( systems are locked out, the scan stops and only the revert system is received.

) indicator disappears to indicate that the sys-

) indicator flashes during fixed scanning. If all

■ Drop-out Delay Time (Scan Resume Time)

If a call is received during scan, the scan stops. The scan resume time can be programmed as 0 to 300 seconds in one-second increments. The default value is 3 seconds.

) indicator

■ Dwell Time

The dwell time is the time after transmission ends until the scan resumes in scan mode. It can be set 0 to 300 seconds by programming. The default value is 3 seconds.

■ System/Group Revert

System/group revert can be programmed for one of the following;

• Last Called Revert

The system or group changes to the revert system or group when a call is received with the system or group being scanned.

• Last Used Revert

If a system/group call is received during scanning and the PTT button is pressed for transmission and response within the drop out delay time, the system or group is assigned as the new revert system or group.

• Selected Revert

If the system/group was changed while scanning, the newly selected system/group.

• Selected + Talkback Revert

If the system/group was changed while scanning, the newly selected system/group. The transceiver “talks back” on the current receive group.

■ Scan Massage Wait

The time for staying with the home repeater that receives a signal during system scan and monitoring data messages can be programmed. If there is no signal from the home repeater, the system is scanned for about 50ms. If there is a signal, three data messages are monitored. Normally, three data messages are monitored for each system, and it can be increased in multiples of three data messages per line to up to eight lines.

If the repeater data message indicates that there is no call, data monitoring is terminated and the home repeater of the next system is scanned.

■ Group Scan Operation

Group scan can be programmed for each group. In addition to the ID codes of the selected group, the ID codes of the other groups that are permitted for group scan are decoded. (The two fixed ID and block decode codes are always decoded.)

If, during group scanning, a call is received with one of the selectable group ID codes for which group scan is enabled, the group display indicates the group number that the call came in with. That group then becomes the new selected group. Group scan resumes after the specified dropout delay time or dwell time shared by the system scan elapses.

■ In Conventional System

If QT or DQT is set for the group, the groups, including

signalling, are scanned.

In case of the priority group is set in conventional system, if a group scan (including group scan during a system scan) temporarily stops (receiving) in a group that does not have priority, a look back is performed to the priority group. Look back is performed according to the look back time A and B settings. If a call is received on the priority group, reception immediately switches to the priority group.

4. Details of Features

■ Time-out Timer

The time-out timer can be programmed in 15 seconds increments from 15 seconds to 10 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.

■ Sub LCD Display

You can use 3-digit the display to display the system number or group number. It is useful when the main (12digit) display indicates system, group name or other functions.

■ Selective Call Alert LED

You can select whether or not the LED on the transceiver flashes in an orange color when selective call was occurred.

■ 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.

■ Timed Power Off

This function works as “Automatic Power Switch Off”.

Timed power off timer starts from the ignition-off. After the timer expires, the radio will automatically turn off. The timer will be reset if the ignition is turned on and off.

This function requires ignition-sense. Connect the ignition-line to the 9-pin connector which is located at the rear of the radio.

After the timer expires, press the power switch to turn on the radio.

■ Horn Alert

Horn alert can be set to on or off for each group. If horn alert has been set to YES for a group and DEC ID/QT/DQT/ MSK matches, the horn alert, HOR. is turned on and off. The group for which the optional signalling is set works by ANDing the decode ID/QT/DQT/MSK with the optional signalling.

Either continuous or non-continuous operation can be set by the FPU. The horn alert port is enabled or disabled as follows;

Off hook horn alert

Enable Yes Yes

Disable No Yes

Hook off Hook on

■ PTT ID

PTT ID provides a DTMF or MSK (FleetSync™ : Fleet-ID) ANI to be sent with every time PTT (beginning of transmission, end of transmission, or both).

You can program PTT ID for each group. You can program PTT ID as “on” or “off” when “DTMF” is selected for the PTT ID type. You can program a PTT ID as “own”, “sel” or “off” when “MSK” is selected for the PTT ID type. The contents of ID are programmed for each transceiver.

The timing that the transceiver sends ID is programmable.

BOT : DTMF ID (BOT)/MSK ID is sent on beginning of

transmission.

EOT : DTMF ID (EOT)/MSK ID is sent on end of transmis-

sion.

Both : DTMF ID (BOT)/MSK ID is sent on beginning of

transmission and DTMF ID (EOT)/MSK ID is sent on end

of transmission.

■ Radio Password

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.

■ Non-continuous

The horn alert port, HOR, is turned on and off as follows;

■ Free System Ringback

This feature is available only when a telephone interconnected ID code is selected. If a busy tone sounds when the PTT button is pressed, the transceiver enters this mode automatically.

When the PTT button is released, a beep sounds for 400ms to indicate that the mode has been entered. If the scan is on, it is resumed (the “SCN” mark goes on). When any repeater becomes available, a ringing tone sounds and this mode ends.

The mode is terminated when the system, group, scan, PTT, key is changed.

■ System Search

This feature can be programmed to automatically access other programmed systems when the selected system cannot be accessed. If an intercept tone sounds when the PTT button is pressed after setting the mode, the transceiver has entered the mode.

If the group ID is a telephone interconnect ID, the transceiver then attempts to access, in succession, other systems that have a telephone interconnect ID in the revert group location. If the group ID is a dispatch ID, the transceiver attempts to access other systems that have a dispatch ID programmed in the revert group location.

If there is no system to be accessed, an intercept tone sounds, the mode is terminated, and the transceiver returns to the first system. If the access is successful, the mode is terminated, and the searched system becomes the new selected system (If during scanning, the scan stops).

Q27

■ Call Indicator

The call indicator can be programmed for each group. In trunked system, it can be set to respond to a selectable decode ID or one of two fixed IDs, except block IDs. When a call is received with a selectable decode ID, the call indicator flashes. When a call is received with a fixed ID, the call indicator lights continuously.

On a conventional system, the call indicator can be programmed to light for each QT or DQT code. It keeps flashing while a call is being received. It is turned off by pressing any front panel key.

■ Transpond

This feature can be programmed to turn on and off for each group. If the ID of the group for which transpond is enabled is received, two data messages (transmit ID and turn-off code) are automatically transmitted if the PTT button is not pressed as a response within the time set (0 to 300 seconds in 1-second increments). If the PTT button is pressed within the time, the transpond is not preformed.

■ Data TX with QT/DQT

Whether programmed QT/DQT is modulated or not with a data transmission except for Selcall. A radio unit can receive a data message regardless of QT/DQT if the receiving unit is not scanning.

■ Transmit Inhibit

The transceiver can be programmed with a transmit inhibit block of ID codes. If an ID code within this block is decoded the preset time before the PTT button is pressed, transmission is inhibited. The BUSY indicator lights and a busy tone sounds until the PTT button is released to indicate that transmission is not possible (except clear-to talk mode).

Transmission with the group for which the encode ID is not set is inhibited, and the busy tone is output while the PTT button is held down, regardless of the clear-to talk setting.

OPERATING FEATURES

TK-980/98 1

■ Auto TEL

A telephone interconnect call can be made by simply pressing the key by assigning this feature to the key. This feature accesses the TEL channel of the available system automatically.

When the key is pressed, a queue tone is output, and the “AUTO TEL” appears on the alphanumeric display along with a flashing handset indicator ( mode has been entered. If the TEL ID is set for the revert system, the TEL channel of that system is accessed. If all TEL channels are busy, an attempt is made to access the TEL channels of another system in which the TEL ID code has been programmed. It is repeated for 60 seconds until the access succeeds. If the access succeeds, a dial tone returns from the repeater. If the key is pressed again when the queue tone is sounding, this mode is canceled.

If the access fails after 60 seconds, a deny tone is output and this mode is terminated. When the talk ends, the revert system/group returns. When the scan mode is effective, the scan resumes. The Auto TEL feature can be programmed to turn on or off for each system.

■ ARQ Mode

If affects Trunking mode only. Automatic Repeat reQuest (ARQ) mode is a manner to minimize the air traffic of data communication. Also, it enables to occupy the trunking repeater channel for the data communication period.

5. Option Signalling

5-1. DTMF

Built-in DTMF 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 which is set up with option signalling, the option signalling indicator ( flash and option signalling will be released. The transpond or alert tone will sound.

If the selective call alert LED is set up, the orange LED will flash.

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

■ AND/OR

You can select AND or OR for option signalling match conditions.

Alert/Transpond

AND QT/DQT/ID+DTMF; Option matches = Action

OR QT/DQT/ID+DTMF; Option matches = Action

AF mute open

AND QT/DQT/ID+DTMF; Option matches = Action

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

) will

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 group 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.

■ 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 group, 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.

5-2. MSK

Built-in MSK (FleetSync™ : Fleet-ID) decoder is available for option signalling. When the group ID matches, squelch remains muted while the station waits for reception of proper MSK signal. When MSK signal matches, squelch unmutes.

■ AND/OR

AND : QT/DQT/ID + MSK to unmute. MSK matches = alert tone

OR : QT/DQT/ID to unmute. MSK matches = alert tone

Alphanumeric Two-way Paging Function

(FleetSync™)

■ General

The Alphanumeric Two-way Paging Function (FleetSync™) is a Kenwood proprietary protocol. It enables a variety of paging functions.

■ ID Construction

A radio unit ID is defined by a combination of 3-digit Fleet and 4-digit ID numbers. Each radio unit must be assigned its own Fleet and ID numbers.

■ PTT ID

A pre-programmed unique ID (own) can be sent at the beginning of transmission and/or the end of transmission to identify which radio unit is on air.

When selecting (sel) for MSK ID, the radio calls he specific Fleet user the same as selective call.

TK-980/98 1

OPERATING FEATURES

■ Selective Call (SELCALL)

This is a voice call to a particular individual or group of

stations.

• Example of Call Types;

[100][ALL ] : <Group Call> All the units whose fleet number is “100” are called. [100][1000] : <Individual Call> The unit, whose the fleet number is “100” and ID number is “1000”, is called. [ALL][ALL ] : <Broadcast Call> All the units are called. [ALL][1000] : <Supervisor Call> All ID “1000” are called regardless of their fleet number.

• Unit ID Encode Block

Encode ID Block can be set to limit manual dial ID. The radio unit will not accept an ID other than these IDs which are entered from the keypad. If Inter-fleet Call is enabled, block ID setting affects each fleet group.

■ Status Message

■ Parameters

• GTC Count

Number of Go To data Channel messages to be sent be-

fore transmitting a data message if it is being made on Data System/ Group. If a radio unit receives a GTC message, it will move to the Data System/Group of the current system. Increase this item to make sure the called radio unit moves to the Data System/Group.

• Random Access (Contention)

When a channel (or all the repeater channels for Trunking

mode) is busy, radio unit will not transmit (depending on its Busy Channel Lockout setting in conventional mode). As soon as a channel is cleared, some transmissions may crash. Random access is used to avoid this by employing a random transmission sequence.

• GPS Time Mark (Per Mobile)

The amount of time from the 0 (zero) minute of the standardized GPS UTC time to starting the first transmission of GPS data. It must be set to a different value for each radio unit to avoid a transmission crash.

• Send GPS

Pressing this key causes the transceiver to send a single GPS data.

• GPS Report On Data Group

GPS data transmission is made on the Data System/ Group.

• Number of Retries

Number of Retries is the maximum number of retry transmission when no acknowledgement is received in the Maximum ACK Wait Time. Increase this item to improve data communication reliability.

• TX Busy Wait Time

TX Busy Wait Time is the maximum amount of time before giving up the data transmission when the channel (or all the repeater channels for Trunking mode) is busy. Also, this timer affects if it expires during Random Access period.

• Maximum ACK Wait Time

Maximum ACK Wait Time is the maximum amount of time to wait for an acknowledgement from the called radio unit. It is used as an interval time of retries. It must be set greater than the ACK Delay Time of the called radio unit.

TK-980/98 1

OPERATING FEATURES

• ACK Delay Time

ACK Delay Time is the amount of time from the end of receiving a data to the beginning of sending an acknowledgement. It should be adjusted as the repeater’s hang-up delay time. Also, it must be set less than the Maximum ACK Wait Time of the calling radio unit.

• TX Delay Time (RX Capture)

TX Delay Time is the amount of unmodulated transmission to let the called unit stop scanning or exit its battery save mode. It is used only when starting a data communication sequence.

• Data TX Modulation Delay Time

Data TX Modulation Delay Time is the amount of time from the beginning of transmission to the beginning of a data modulation. It is used every time data is transmitted. It must be set to more than 300ms if data communication is made in Trunking Mode.

5-1. Preface

The transceiver is programmed by using a personal com-

puter, programming interface (KPG-46) and programming software (KPG-49D).

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 transceiver to the personal computer with the interface cable.

2. When the Power switch on, user mode can be entered immediately. When PC sends command the radio enter PC mode, and “PROGRAM” is displayed on the LCD. When data transmitting from transceiver, the red LED is blinking. When data receiving to transceiver, the green LED is blinking.

Notes :

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

• Change the transceiver 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 transceiver 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 Ttransceiver to the computers RS-232C serial port.

5-4. Programming Software Description

The KPG-49D programming disk is supplied in 3-1/2" disk

format. The software on this disk allows a user to program the transceiver radio via programming interface cable (KPG-

46).

IBM-PC

KPG-46

5-5. Programming With IBM PC

If data is transferred to the transceiver from an IBM PC with the KPG-49D, the destination data (basic radio information) for each set can be modified. Normally, it is not necessary to modify the destination data because their values are determined automatically when the frequency range (frequency type) is set.

The values should be modified only if necessary.

Data can be programmed into the flash memory in RS232C format via the modular microphone jack.

KPG-49D instruction manual parts No. : B62-1096-XX.

Note :

Normally, write in the high-speed mode.

7. 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 a slave).

1. Turn the master radio power ON with the [C] key held down. If the password is set to the radio, the radio displays “CLONE LOCK”. If the password is not set, the radio displays “CLONE MODE”.

2. When “CLONE LOCK” is displayed, only the [System up/ down] key and [SCN], and [0] to [9] keys can be accepted. When you enter the correct password, and “CLONE MODE” is displayed, the radio 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 “CLONE LOCK” is displayed, the number that was pressed is displayed on the radio. Each press of the key shifts the display in order to the left. When you enter the password and press the [SCN] key, “CLONE MODE” is displayed if the entered password is correct. If the password is incorrect, “CLONE LOCK” is redisplayed. How to enter the password with the [System up/down] key; If the [System up/down] key is pressed while “CLONE LOCK” is displayed, numbers (0 to 9) are displayed flashing. When you press the [SCN] key, the currently 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 MODE” is displayed if the entered password is correct. If the password is incorrect, “CLONE LOCK” is redisplayed.

4. Power on the slave radio.

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 MODE”. The data of the master is sent to the slave. While the slave is receiving the data, “PROGRAM” is displayed. When cloning of data is completed, the mater 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 MODE”. Carry out the operation in step 4 to 6.

Note :

Only the same models can be cloned together.
