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 this publi-

cation 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

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. You must connect the positive power lead directly to

the positive terminal of the vehicle battery. Never

connect the lead to any other positive power source,

such as a cigarette lighter jack or fuse terminals.

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. You must also connect the ground lead directly to

the negative terminal of the vehicle battery.

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.

TK-880/H

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.

bler board is not installed.

If this key is pressed, an underscore (“_”) appears at the

extreme right of the LCD and AUX port which is inside of the

transceiver turns to the active level. If pressed again, the

underscore disappears and the AUX ports turns to the

deactive level.

•Channel up/down (Conventional format)

When the key is pressed each time, the channel number

to be selected is incremented/decremented and repeats if

held for one second or longer. This key works as the voice

scrambler code selector in the voice scrambler code select

mode.

OPERATING FEATURES

•DTMF ID (BOT)

In conventional mode, if you press this key, a predeter-

mined DTMF ID (Begin of TX) will be sent automatically.

•DTMF ID (EOT)

In conventional mode, if you press this key, a predeter-

mined DTMF ID (End of TX) will be sent automatically.

•Display character

This key switches the LCD display between the system

and group number in trunking format and the group and

channel name in conventional format.

•Emergency

Pressing this key for longer than the programmed “Emer-

gency Key Delay Time” causes the transceiver to enter the

emergency mode. The transceiver jumps to the pro-

grammed “Emergency system and group in trunking format

and the group and channel in conventional format” and

transmits for the programmed “Active Time”.

The transceiver disables mic mute while transmitting.

After finishing transmission, the transceiver receivers for

the programmed “Interval Time”. The transceiver mutes

the speaker while receiving. Following the above sequence,

the transceiver continues to transmit and receive.

•Function

Pressing this key causes the transceiver to display

“FCN”. Then, pressing a microphone DTMF key causes the

corresponding programmed function to start. This key may

be convenient when using many functions with the micro-

phone 12-key keypad.

numeric Two-way Paging Function” for details)

•Memory

This key allows DTMF memory data to be recalled; up to

32 memories each with a memory dial of up to 16 digits and

an A/N of up to 10 digits per memory.

•Monitor

Used to release signalling or squelch when operating as a

conventional. It is also used to reset option signalling.

•Operator selectable tone (Conventional format)

This key switches the pre-set decode QT/DQT and en-

code QT/DQT to OST (Operator Selectable Tone) tone pair.

Press this key, the transceiver enters to OST select

mode. In this mode, the display shows “OFF” and the op-

erator can select one of the OST tone pair using the group

up/down key. The display shows “TONE**” and tone

pair No. ** is selected.

Press OST key again, the transceiver exits from the OST

select mode, and returns to the group/channel mode with

the handset indicator ( ). The handset indicator ( ) means

that the OST tone pair is selected. OST tone pair number or

OFF can be memorized for each channel.

16 kinds of tone pair for OST can be programmed by

KPG-49D. OST is useful to access the repeater with same

radio frequency and different tone (QT/DQT).

•Public address

Public address amplifies the microphone audio, and out-

puts it through a PA speaker. PA is activated by pressing

this key. A confirmation tone sounds, and the display shows

“PUBLIC ADRS”. PA can be activated at anytime (scanning

or non-scanning).

The RADIO continues to scan & receive calls while in PA

mode. Pressing PTT activates PA, and will override an in-

coming call at anytime; however, no RADIO transmission

takes place.

If this key is pressed again, a confirmation tone will

sound, the display will return to the normal channel or SCAN

display, and the PA function will turn off.

•Redial

If you press this key when the system/group (Trunking

format) or group/channel (Conventional format) is displayed,

the last transmitted DTMF code will appear on the display.

Pressing the PTT switch at this time will transmit the dis-

played DTMF code.

•Scan

Press this key starts scanning. Pressing this key stops

scanning.

•Scan del/add

1) Trunking format

Used to select whether system scan routines are used

during system scan. Each pressing of the key (to ON)

toggles between lockout and lock. The scan routine is

started when on lock. The DEL indicator flashes when the

system is on lockout.

2) Conventional format

This key switches the currently displayed channel be-

tween “Delete” and “Add”.

The “Add” channel contained in the scan sequence, and

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

key switches the channnel delete or add temporarily.

•Scan temporary delete (Trunking format)

This key is temporarily deleted a system being scanned.

If you press this key when scan is stopped (when a call is

being received from another station), the system is tempo-

rarily deleted and scanning restarts.

This key operates even when “Scan Type” is set to “List

Type System Scan”.

•Scrambler

If a scrambler code (1 to 16) has been set in the FPU, an

underscore (“_”) appears at the extreme right of the LCD

display when scrambler is active. Pressing this key changes

on/off of scramble operation. Press this key for 2 seconds

to enter scrambler code selection mode.

•Send GPS (Optional)

3-1. Trunking Format

■System scan

System scan can be selected with the “Scan” key by pro-

gramming the scan feature. When the “Scan” key is

pressed and the “SCN” mark appears, scan mode in en-

tered. Scanning starts from the system following the cur-

rently 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.

Fig. 1

TK-880/H

■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 ( ) indicator

appears on the left of the SYSTEM indicator. The revert sys-

tem is scanned even if it is locked out. If there is a locked

system, the Delete ( ) indicator flashes during fixed scan-

ning.

•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 ( ) indicator

is displayed on the left of the SYSTEM indicator.

To unlock a system, select the system and press the key.

The Delete ( ) indicator disappears to indicate that the sys-

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 ( ) indicator flashes during fixed scanning. If all

systems are locked out, the scan stops and only the revert

system is received.

■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.

■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 sec-

onds 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 be-

ing 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.

OPERATING FEATURES

•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 re-

ceives 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 sys-

tem, and it can be increased in multiples of three data mes-

sages 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 addi-

tion to the ID codes of the selected group, the ID codes of

the other groups that are permitted for group scan are de-

coded. (The two fixed ID and block decode codes are al-

ways decoded.)

If, during group scanning, a call is received with one of

the selectable group ID codes for which group scan is en-

abled, the group display indicates the group number that the

call came in with. That group then becomes the new se-

lected group. Group scan resumes after the specified drop-

out delay time or dwell time shared by the system scan

elapses.

■In conventional system

If QT or DQT is set for the channel, the channels, includ-

ing signalling, are scanned.

In case of the priority group is set in conventional sys-

tem, 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.

3-2. Conventional Format

■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.

TK-880/H

■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 func-

tion, the scan starts. The scan icon “SCN” lights and “–

SCAN–” or revert channel (programmable) 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.

■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 chan-

nel up/down key when the scan does not occur, adds an

indicator “▼” lights.

■Priority channel setting

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

ming software (KPG-49D).

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 chan-

nel 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-49D).

1) Priority

The transceiver reverts to the priority channel.

2) Priority + 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 cur-

rent channel to answer to the call however revert channel

is set to priority channel.

After resume time, scan re-starts and transmission chan-

nel 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 in-

cludes talkback function.

6) Selected + 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–” or revert channel

(programmable) display goes off.

■Temporarily delete/add

It is possible to delete or add channel temporarily during

scan. When scan stops on unnecessary channel for ex-

ample 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 tempo-

rarily 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.

■Time-out timer

The time-out timer can be programmed in 15 seconds

increments from 15 seconds to 10 minutes. If the transmit-

ter 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.

OPERATING FEATURES

■Sub LCD display

You can use 3-digit the display to display the system

number, channel number or group number. It is useful

when the main (12-digit) display indicates system, group or

channel 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.

■PTT ID

PTT ID provides a DTMF or MSK (FleetSync™ : Fleet-ID)

ANI to be sent with every time PTT (beginning of transmis-

sion, end of transmission, or both).

You can program PTT ID for each group. You can pro-

gram a 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 program-

mable.

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 "S" key.

■Off hook decode

If the Off hook decode function has been enabled, re-

moving 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 igni-

tion-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.

OPERATING FEATURES

■Horn alert

In trunking format, 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 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 with the optional

signalling.

In conventional format, if you are called from the base

station using 2-tone/DTMF while you are away from your

transceiver, you will be alerted by the vehicle horn or some

other type of external alert. To turn horn alert function on,

press the [Horn Alert] key.

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

Hook off Hook on

Enable Yes Yes

Disable No Yes

■Pulse

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

The timing when the fixed LTR ID matches is as follows

(trunking format);

■Continuous

Horn alert can be reset by setting an expiration time from

the FPU, pressing the AUX-A key, or setting off hook.

■Data TX with QT/DQT

Whether programmed QT/DQT is modulated or not with

a data transmission except for Selcall. A radio unit can re-

ceive a data message regardless of QT/DQT if the receiving

unit is not scanning.

OPERATING FEATURES

4-2. Trunking Format

■Call indicator

The call indicator can be programmed for each group. In

trunked system, it can be set to respond to a selectable de-

code 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 pro-

grammed to light for each QT or DQT code. It keeps flash-

ing while a call is being received. It is turned off by pressing

any front panel key.

■Free system ringback

This feature is available only when a telephone intercon-

nected ID code is selected. If a busy tone sounds when the

PTT button is pressed, the transceiver enters this mode au-

tomatically.

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 can-

not 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 trans-

ceiver then attempts to access, in succession, other sys-

tems that have a telephone interconnect ID in the revert

group location. If the group ID is a dispatch ID, the trans-

ceiver attempts to access other systems that have a dis-

patch 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 se-

lected system (If during scanning, the scan stops).

■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 but-

ton 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.

■Transmit inhibit

The transceiver can be programmed with a transmit in-

hibit 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 set-

ting.

■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 ( ) to indicate that this

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 pro-

grammed to turn on or off for each system.

■ARQ mode

It 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 fot the data communication pe-

riod.

4-3. Conventional Format

■“TOT” pre-alert

The transceiver has “TOT” pre-alert timer. This param-

eter 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.

■“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.

TK-880/H

OPERATING FEATURES

■“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 ex-

pired.

■OST (Operator Selectable Tone)

The transceiver is capable to have “OST” function and 16

tone pair (QT/DQT) with max 10-digit name for each tone

pair.

■“OST” back up

The transceiver is programmable the selected “OST”

code is memorized or not. If you set to Disable (no memo-

rized), the “OST” function always starts at “off”.

■Direct “OST”

It is possible to call “OST” number directory using key-

pad. In this case, keypad is used for “OST”, then auto

“PTT” store and send functions by keypad are not usable.

■Clear to transpond

The transceiver waits the transpond of 2-tone /DTMF if

channel is busy until channel open. This feature prevents

the interference to other party.

5. Option Signalling

5-1. 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

(*) will 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 (2-tone); Option matches = Action

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

AF mute open

AND QT/DQT/ID+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 (Trunking format).

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 op-

tion signalling, option signalling will temporarily reset auto-

matically.

■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 ap-

pear.

5-2. MSK

Built-in MSK (FleetSync™ : Fleet-ID) decoder is available

for option signalling. When the group ID/Carrier 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 en-

ables 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 the spe-

cific Fleet user the same as selective call.

TK-880/H

■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 num-

ber 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

Using a 2-digit number, you can send and receive a Sta-

tus message which may be decided in your talk group. Each

Status may be displayed with 16 alphanumeric characters if

programmed in the radio. A maximum of 9 received mes-

sages can be stored in the stack memory, and it can be re-

viewed after reception. If the message memory becomes

full, the oldest one will be erased. The stack memory will be

cleared by turning radio power off.

•Status 80~99 (Special)

Status numbers from 80 to 99 are reserved for special

purposes. Entering these statuses from the DTMF keypad

can be inhibited.

Please notice that the following status numbers are used

for special purposes;

80~87 : Reserved for future use.

88 : Terminates to emergency mode.

89 : Request for horn alert.

90 : Remote stun on. Disable the received radio unit’s

TX.

91 : Remote stun on. Disable the received radio unit’s

TX/RX.

92 : Cancel remote stun. Enable the received radio unit’s

TX/RX.

93 : Acknowledgement status sent when the radio unit is

in stun mode (TX disabled).

94 : Acknowledgement status sent when the radio unit is

in stun mode (TX/RX disabled).

95~97 : Reserved for future use.

98 : Man down emergency status (For portable).

99 : Emergency status.

Note : Remote stun works with DTMF D.B.D. function also.

•Automatic status response

If you pre-select a status number and leave the radio in

the Status Mode, it can automatically respond with the se-

lected status number upon request from the base station.

(The request function is initiated by serial control on the

base station (Optional).)

■Short Messase (Optional)

A maximum of 48 characters can be sent (External equip-

ment is required). Received Short Messages will be dis-

played in the same manner as a Status Message. A maxi-

mum of 4 received messages can be stored in the stack

memory. In the Stack Mode, 3-digit LCD indicates the re-

ceived Short Message as “M01”~”M04".

■Long Message (Optional)

A maximum of 1024 characters can be sent (External

equipment is required). Received Long Message will not be

displayed or stacked in the radio memory but is output

through the COM (Data) port.

■Emergency Function

Emergency status 99 will be sent at the beginning of

each emergency transmission.

•Emergency status response

Either “Horn” or “Alert” can be selected for the called

radio unit’s response to reception of status 99 which is used

as an emergency status.

■Other Functions

•Manual dial

Fleet, ID and Status numbers can be entered from DTMF

keypad. (DTMF microphopne is required.)

•FleetSync™ baud rate

MSK data baud rate setting. The same rate must be set

as a communication partner.

1200bps :

Data communication is made in 1200bps. The communi-

cation area is much wider than 2400bps. Recommended

for repeater operation.

2400bps :

Data communication is made in 2400bps. The communi-

cation area is narrower than 1200bps, but it will decrease

the data traffic. Data rate 2400bps may not work prop-

erly depending on the repeater’s characteristic.

•Message mode timer

Message Mode Timer is a delay timer returning from

message/stack mode to Normal mode.

•Status/short/long message on data group/channel

Status/Short/Long Message transmission is made

whether on the Data System/Group in trunking format and

on the Data Group/Channel in conventional format.

OPERATING FEATURES

dardized 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/channel

GPS data transmission is made on the Data System/

Group in trunking format and on the Data Group/Channel in

conventional format.

•Received GPS data output

Any selected sentence can be output through the radio

serial port (COM1 or COM0).

1) MAP HEADER NMEA1 ($GPGGA), NMEA2 ($GPGLL),

NMEA3 ($GPRMC)

NMEA-0183 standard command. This should be set ac-

cording to your PC application.

2) MAP HEADER KW1 ($PKLDS)

This is a Kenwood original sentence which consists of

“$GPGLL + Fleet + ID + Status”. This item should be set

according to your PC application.

3) MAP HEADER KW2 ($PKLID)

This is a Kenwood original sentence which consists of

“Fleet + ID”. This should be set according to your PC

application.

■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 in trunking format and the Data

Group/Channel in conventional format.

•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.

•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 be-

fore 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.

OPERATING FEATURES

TK-880/H

•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 Maxi-

mum ACK Wait Time of the calling radio unit.

•TX delay time (RX capture)

TX Delay Time is the amount of unmodulated transmis-

sion to let the called unit stop scanning or exit its battery

save mode. It is used only when starting a data communica-

tion 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.

7. Audible User Feedback Tones

5-1. Preface

The TK-880/880H transceiver is programmed by using a

personal computer, 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 TK-880/880H 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 TK-880/880H 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-880/880H 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-880/880H 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

TK-880/880H radio via programming interface cable (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 informa-

tion) for each set can be modified. Normally, it is not neces-

sary to modify the destination data because their values are

determined automatically when the frequency range (fre-

quency type) is set.

The values should be modified only if necessary.

Data can be programmed into the flash memory in RS-

6. Firmware Programming Mode

6-1. Preface

Flash memory is mounted on the TK-880/880H. This al-

lows the TK-880/880H 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-880/880H to the personal computer (IBM

PC or compatible) with the interface cable (KPG-46). (Con-

nection is the same as in the PC Mode.)

6-3. Programming

1. Start up the programming software (KPG-49D), select

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

the Return key on the 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-880/880H Power ON with the [SCN] switch

held down. Hold the switch down for two seconds until

the display changes to “PROG 57600”. When “PROG

57600” appears, release your finger from the switch.

6. Check the connection between the TK-880/880H and the

personal computer, and make sure that the TK-880/880H

is in the Program mode.

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

on the display to indicate progress of writing. When the

TK-880/880H starts to receive data, the [P] icon is blink-

ing.

8. If writing ends successfully, the LED on the TK-880/880H

lights and the checksum is displayed.

9. If you want to continue programming other TK-880/880H,

repeat steps 5 to 8.

REALIGNMENT

Notes :

• To start the Firmware Programmer from KPG-49D, the

FPRO path must be set up by KPG-49D setup.

• This mode cannot be entered if the Firmware program-

ming mode is set to Disable in the Programming soft-

ware (KPG-49D).

• When programming the firmware, it is recommend to

copy the data from the floppy disk to your hard disk be-

fore 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 57600” is

displayed, the checksum is displayed. If you press the

[MON] switch again while the checksum is displayed,

“PROG 57600” is redisplayed.

2. If you press the [D] switch while “PROG 57600” is dis-

played, the display changes to “PROG 19200” to indicate

that the write speed is low speed (19200 bps). If you

press the [D] switch again while “PROG 19200” is dis-

played, the display changes to “PROG 38400”, and the

write speed becomes the middle speed (38400 bps). If

you press the [D] switch again while “PROG 38400” is

displayed, the display returns to “PROG 57600”.

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 TK-880/880H power ON with the [C] key

held down. If the password is set to the TK-880/880H,

the TK-880/880H displays “CLONE LOCK”. If the pass-

word is not set, the TK-880/880H displays “CLONE

MODE”.

2. When “CLONE LOCK” is displayed, only the [System up/

down] key (Trunking format), the [Group up/down] key

(Conventional format) and [SCN], and [0] to [9] keys can

be accepted. When you enter the correct password, and

“CLONE MODE” is displayed, the TK-880/880H 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 TK-880/

880H. 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 (Trunking format), the [Group up/down] key (Conven-

tional format);

If the [System up/down] key (Trunking format), the

[Group up/down] key (Conventional format) 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 dis-

played if the entered password is correct. If the pass-

word is incorrect, “CLONE LOCK” is redisplayed.

4. Power on the slave TK-880/880H.

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

modular microphone jacks on the master and slave.

6. Press the [S] 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, “PRO-

GRAM” 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 oper-

ated by the same program as the master.

7. The other slave can be continuously cloned. When the

[S] key on the master is pressed while the master dis-

plays “END”, the master displays “CLONE MODE”.

Carry out the operation in step 4 to 6.

Note :

Only the same models can be cloned together.

TK-880/H

Frequency Configuration

The TX-RX unit (A/2) incorporates a VCO, based on a frac-

tional N type PLL synthesizer system, that allows a channel

step of 5, 6.25kHz to be selected. The incoming signal from

the antenna is mixed with a first local oscillation frequency

to produce a first intermediate frequency of 44.85MHz.

The signal is then mixed with a second local oscillation

frequency of 44.395MHz to produce a second intermediate

frequency of 455kHz. This is called a double-conversion

system. The TX-RX unit (A/2) contains a wide/narrow MCF

and CFs. The transmit signal is produced by the PLL circuit

for direction oscillation and division. The signal output from

the VCO is amplified by a straight amplifier and transmitted.

Fig. 1 Frequency configuration

Receiver System

■Outline

The incoming signal from the antenna passes through a

low-pass filter and a transmission/reception selection diode

switch (TK-880 : D209, D210, D211, TK-880H : D402, D210,

D211) and goes to the front end of the receiver. The front-

end filter is a variable BPF consisting of two two-pole helical

resonators and eight varicap diodes (K3,HK3 : D203~D206,

D212~D215, K,K2,HK,HK2 : D203~D206) to eliminate un-

wanted out-of-band signal components. The low-noise am-

plifier (LNA) (Q201) uses a bipolar transistor to achieve wide-

band and low-distortion amplification.

The signal passes through a BPF and is down-converted

with the first local signal by IC200, then converted to the

first IF signal of 44.85MHz. The first local signal passes

through an LPF and an attenuator to eliminate unwanted

harmonics components and implement the optimum input

level to the mixer, then enters IC200. A DBM is used as a

mixer to achieve a high potential.

The signal output from the mixer is amplified by an inter-

mediate frequency amplifier and input to two MCFs (XF1).

The signal is amplified by another intermediate amplifier and

goes to the FM IF IC (IC11). The first intermediate fre-

quency signal is mixed with the second local signal of

44.395MHz to produce the second IF signal of 455kHz.

The unwanted near-by signal components are then elimi-

nated by a wide ceramic filter (CF1) or a narrow ceramic fil-

ter (CF2) and the resulting signal goes back to the FM IF IC.

The signal is quadrature-detected in the IC to produce an

audio signal, which is amplified by a DET amplifier (IC2) and

output to the TX-RX unit (B/2).

■Wide/Narrow Changeover Circuit

The W/N port (pin 11) of the shift register (IC7) is used to

switch between ceramic filters. When the W/N port is high,

Q24 turns on and the ceramic filter SW diode (D22, D23)

CF1 turns on to receive a Wide signal. At the same time,

Q16 turns on and one of the filters is selected so that the

wide and narrow audio output levels are equal.

When the W/N port is low, Q23 turns on and the ceramic

filter SW diode (D22, D23) CF2 turns on to receive a Narrow

signal.

■AF Signal System

The detection signal (DEO) from the TX-RX unit (A/2)

goes to the audio processor (IC504) of the TX-RX unit (B/2).

The signal passes through a filter in the audio processor to

adjust the gain, and is output to IC502. IC502 sums the AF

signal and the DTMF signal and returns the resulting signal

to the TX-RX unit (A/2). The signal (AFO) sent to the TX-RX

unit (A/2) is input to the D/A converter (IC5). The AFO out-

put level is adjusted by the D/A converter. The signal output

from the D/A converter is added with the BEEP signal (BPO)

and the resulting signal is input to the audio power amplifier

(IC10). The AF signal from IC10 switches between the inter-

nal speaker and speaker jack (J1) output.

■Squelch Circuit

The detection output from the FM IF IC (IC11) is ampli-

fied by IC2 and the signal (DEO) is sent to the TX-RX unit (B/

2). The signal passes through a high-pass filter and a noise

amplifier (Q503) in the TX-RX unit (B/2) to detect noise. A

voltage is applied to the CPU (IC511). The CPU controls

squelch according to the voltage (ASQ) level. The signal

from the RSSI pin of IC11 is monitored. The electric field

strength of the receive signal can be known before the ASQ

voltage is input to the CPU, and the scan stop speed is im-

proved.

Transmitter System

■Outline

The transmitter circuit produces and amplifies the de-

sired frequency directly. It FM-modulates the carrier signal

by means of a varicap diode.

■VCO/PLL Circuit

The TK-880/880H has a VCO for the transmitter and a

VCO for the receiver in a sub-unit (A1). They are housed in a

solid shielded case and connected to the TX-RX unit (A/2)

through CN101. One of the VCOs is selected with an ST

signal. A filtered low-noise power supply is used for the

VCOs and varicap diodes.

The VCO for the transmitter is described below. It is de-

signed so that Q103 turns on with a prescribed frequency

when a reverse bias is applied to D102 and D104 by using

the control voltage (CV) through CN101. The control voltage

is changed by turning the trimmer capacitor (TC109). The

output from Q103 is applied to the buffer amplifier (Q106) to

generate a VCO output signal. This signal is used as a drive

input signal or a local signal of the first mixer. Since a signal

output from Q106 is input to the PLL IC, it passes through

CN101 and buffer amplifier (Q300) and goes to the PLL IC

(IC300). The modulation signal from CN101 is applied to

D105 and passes through C112 and C113 to modulate the

carrier.

The PLL IC uses a fractional N type synthesizer to im-

prove the C/N ratio and lock-up speed. The VCO output sig-

nal input to the pin 5 of the PLL IC is divided to produce a

comparison frequency according to a channel step. This sig-

nal is compared with the reference frequency which is out-

put from the VCXO (X1). VCXO provides 16.8MHz, 2.5ppm

(–30 to +60°C) and guarantees stable performance when

the temperature changes. The output signal from the phase

comparator passes through a charge pump in the PLL IC and

an external active LPF (Q301, Q302) to generate a DC VCO

control voltage CV. Serial data (DT, CK, EP) are output from

the CPU (IC511) and shift register (IC8) in the TX-RX unit (B/

2) to control the PLL IC. The PLL lock status is always moni-

tored by the CPU.

■Unlock Circuit

During reception, the TR signal goes high, the KEY signal

goes low, and Q10 turns on. Q11 turns on and a voltage is

applied to the collector (8R). During transmission, the TR

signal goes low, the KEY signal goes high and Q13 turns on.

Q12 turns on and a voltage is applied to 8T.

The CPU in the TX-RX unit (B/2) monitors the PLL (IC300)

LD signal directly. When the PLL is unlocked during trans-

mission, the PLL LD signal goes low. The CPU detects this

signal and makes the KEY signal low. When the KEY signal

goes low, no voltage is applied to 8T, and no signal is trans-

mitted.

Q17 turns the PC signal on or off using 8T so that the

circuit works only during transmission. With stability at low

power in mind, Q29 turns off to optimize the detection volt-

age.

The APC circuit is configured to protect overcurrent of

the power module due to fluctuations of the load at the an-

tenna end and to stabilize transmission output at voltage

and temperature variations.

Control Circuit

The CPU carries out the following tasks:

1) Controls the shift register (IC7, IC8, IC508) AF MUTE,

WIDE/NARROW, T/R KEY outputs.

2) Adjusts the AF signal level of the audio processor (IC504)

and turns the filter select compounder on or off.

3) Controls the DTMF decoder (IC507).

4) Controls the LCD assembly display data.

5) Controls the PLL (IC300).

6) Controls the D/A converter (IC5) and adjusts the volume,

modulation and transmission power.

■Power Amplifier Circuit

The transmit output signal from the VCO is amplified to a

specified level of the power module (IC400) by the drive

block (Q202, Q204, Q205). The amplified signal passes

through the transmission/reception selection diode (D209)

and goes to a low-pass filter. The low-pass filter removes

unwanted high-frequency harmonic components, and the

resulting signal is goes the antenna terminal.

■APC Circuit

The automatic transmission power control (APC) circuit

detects part of a power module output with a diode (D27,

D30) and applies a voltage to Q21. Q21 compares the APC

control voltage (PC) generated by the D/A converter (IC5)

and DC amplifier (IC6) with the detection output voltage to

control Q19 and Q20, generates DB voltage from B voltage,

and stabilizes transmission output.

The transceiver has a 2M-bit (256k x 8) flash ROM

(IC510) and an 8k-bit EEPROM (IC512). The flash ROM con-

tains firmware programs, data and user data which is pro-

grammed with the FPU. The EEPROM contains adjustment

data. The CPU (IC511) controls the flash ROM through an

external address bus and an external data bus. The CPU

■Display Circuit

The CPU (IC511) controls the shift register (IC508) and

display LEDs. When the LG line goes high when the trans-

ceiver is busy, Q508 turns on and the green LED on D511

lights. In transmit mode, the LR line goes high, Q509 turns

on and the red light lights. Backlighting LEDs for the key

operation unit (D512~D517) and LCD are provided.

When the KBLC line goes high, Q512 turns on, then

Q513 turns on, and the key illumination LED lights. A volt-

age is applied to the LEDA line to turn on the LCD backlight.

■Key Matrix Circuit

The TK-880/880H front panel has ten keys. Each of them

is connected to a cross point of a matrix of the KEY1 to KEY7

ports of the microprocessor. The KEY5 to KEY7 ports are

always high, while the KEY1 to KEY4 ports are always low.

The microprocessor monitors the status of the KEY1 to

KEY7 ports. If the state of one of the ports changes, the

microprocessor assumes that the key at the matrix point

corresponding to that port has been pressed. Unused

points (KEY1 to KEY7) are also used for foot switch (FSW)

input.

CPU and goes to the audio processor (IC504). An MSK sig-

nal is output from the audio processor according to the data

(AFDAT) from the CPU. The signal is summed with a MIC/

MSK signal by the audio processor (IC504), and the resulting

signal passes through an analog switch (IC506) and goes to

the TX-RX unit (A/2) (MO).

■Horn Control

The horn switch, consisting of Q4, Q5, and Q6, controls

the horn relay. It is supplied by the dealer to provide the

external horn alert function.

Q5 disables horn alert, turning on when its base is high,

to inhibit the function. Normally, the output from IC7 is low,

and Q6 is off; the base of Q4 is about 0V and Q4 is off.

When horn alert is enabled, the output from IC7 goes high

and Q6 turns on. The base current flows through R58 to Q4

to turn Q4 on. Q4 can sink a maximum of 100mA. If the

operational KAP-1 is used, it can drive up to 2A.

■PA Switch

If the optional KAP-1 is used, the PA (Public Address)

function becomes available. In this case, the signal flow

changes as follows;

Power Supply Circuit

When the POWER switch on the TX-RX unit (B/2) is

pressed, the PSW signal goes low. This signal is inverted by

Q26 and sent to a flip-flop IC (IC15). This IC outputs a con-

trol signal when the PSW goes low. When the power turns

on, pin 1 of IC15 outputs a low signal and Q30 turns on. The

base of Q28 goes high, Q28 turns on, SB SW (Q27) turns on

and power (SB) is supplied to the set.

This circuit has an over-voltage protection circuit. If a DC

voltage of 20 V or higher is applied to the power cable, D34

turns on and a voltage is applied to the base of Q31. This

voltage turns Q31 on and turns Q28 and SBSW off. This

circuit has a TIMED POWER OFF (TOF) function which can

be programmed by software.

It is controlled through pin 6 of IC7. When the TOF line

goes high, Q22 turns on and then Q25 turns on. Pin 6 of

IC15 goes high, then pin 1 goes high to turn Q27 off.

• Preparations for tuning the transceiver

Before attempting to tune the transceiver, connect the

unit to a suitable power supply.

Whenever the transmitter is turned, the unit must be

connected to a suitable dummy load (i.e. power meter).

The speaker output connector must be terminated with a

4Ω dummy load and connected to an AC voltmeter and an

audio distortion meter or a SINAD measurement meter at all

times during tuning.

• Transceiver tuning

(To place transceiver in tuning mode)

Channel appears on LCD. Set channel according to tun-

ing requirements.
