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 the publica-
tion data. 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 informa-
tion, 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 re-
quired 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 verified se-
cure and any open connectors are properly terminated.
!SHUT OFF and DO NOT operate this equipment near elec-
trical 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.
2. PRE-INSTALLATION CHECKOUT
2-1. Introduction
Each radio is adjusted and tested before shipment. How-
ever, it is recommended that receiver and transmitter opera-
tion be checked for proper operation before installation.
2-2. 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.

3. PLANNING THE INSTALLATION
3-1. General
Inspect the vehicle and determine how and where the ra-
dio antenna and accessories will be mounted.
Plan cable runs for protection against pinching or crush-
ing 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 sys-
tem 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.

sion.
Both : DTMF ID (BOT)/FFSK ID is sent on beginning of
transmission and DTMF ID (EOT)/FFSK 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 [CALL] key.
"Off hook decode
If the Off hook decode function has been enabled, remov-
ing 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.
"“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.
"“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.
"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 memorized),
the “OST” function always starts at “off”.
"Clear to transpond
The transceiver waits the transpond of DTMF if channel is
busy until channel open. This feature prevents the interfer-
ence to other party.
5. Option Signalling (DTMF)
Built-in DTMF decoder is available for option signalling.
It is possible to use individual call, group call, stun, kill.
Stun and kill are used with DTMF.
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
Option signalling match conditions can be selected with
AND/OR logic.
Alert/Transpond
AND Triggers at match with QT/DQT/ID+DTMF; Both
OR Triggers only for match with DTMF; Option
AF mute open
AND Triggers at match with QT/DQT/ID+DTMF; Both
OR Triggers only for match with QT/DQT/ID; Signalling
Even if set for OR, AF mute cannot be canceled just by a
match with DTMF.
In channels not set with QT/DQT, signalling is a match
just by rceiving the carrier.

"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.
"Stun/Kill
If the stun code matches, a predetermined action will oc-
cur. Whether option signalling is activated or not, when stun
code matches on any channel, the transceiver will become
stun or kill.
While stun is active (“LOCK2” appears), if the stun code +
“#” code is received, stun will disactive. While kill is active
(“ERROR” appears), the transceiver will be disable all func-
tions. The transceiver must be reprogrammed by the FPU
(KPG-77D) to operation again.
6. Alphanumeric Two-way Paging Function
(Digital Message System : DMS)
"General
The Alphanumeric Two-way Paging Function (DMS) 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 can be sent at the begin-
ning of transmission and/or the end of transmission to iden-
tify which radio unit is on air.
"Selective Call (SELCALL)
This is a voice call to a particular individual or group of
stations.
!Example of call types;
[100][ALL ] : <Fleet 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
Using a 2-digit number, you can send and receive a Status
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 15 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;
80~89 : Reserved for future use.
90 : Remote kill on. Disable all transceiver functions.
91 : Remote stun on. The transceiver cannot operate.
92 : Turns stun off.
93 : Spare.
94 : Acknowledgement status sent when the radio unit is
in stun mode.
95~98 : Reserved for future use.
99 : Emergency Status.
Note : Remote stun works with DTMF stun 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 displayed
in the same manner as a Status Message. A maximum of 15
received messages can be stored in the stack memory. In
the Stack Mode, 3-digit LCD indicates the received Short Mes-
sage as “Q1”~“Q15”.
"Long Message
A maximum of 4096 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 ra-
dio 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.)
!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.
!DMS Baud Rate
FFSK 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 properly
depending on the repeater’s characteristic.
!Inter-Fleet Call
Inter-fleet calls allow a radio of one fleet number to call a
radio with a different fleet number (radio users can manually
dial a unit ID with a different fleet number).
! Status/Short/Long Message on Data Group/Channel
Status/Short/Long Message transmission is made whether
on the Data Group/Channel.
!Status/Short/Unit ID Message Serial Output
Whether a received Status/Short message or PTT ID is
outputed or not to serial port.
"GPS Report
A NMEA-0183 GPS unit must be installed.
!GPS Report Mode
GPS data can be sent automatically or upon request. Manu-
ally sending GPS data works regardless of this setting.
Auto : GPS data is sent both automatically and by re-
quest. GPS Auto TX Interval and GPS Time Mark must be
adjusted if required.
Poll : GPS data is sent upon request from dispatcher.
!GPS Report Interval
Interval time between automatic GPS data transmissions.
!GPS Time Mark (Per Mobile)
The amount of time from the 0 (zero) minute of the stan-
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.
