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 publica-
tion 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.
PERSONAL SAFETY
The following precautions are recommended for personal
safety :
•DONOT transmit if someone is within two feet (0.6
meter) of the antenna.
•DONOT 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 CONSIDERATIONS
1. UNPACKING
Unpack the radio from its shipping container and check
for accessory items. If any item is missing, please contact
KENWOOD immediately.
2. LICENSING REQUIREMENTS
Federal regulations require a station license for each
radio installation (mobile or base) be obtained by the
equipment owner. The licensee is responsible for ensuring
transmitter power, frequency, and deviation are within the
limits 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 installa-
tion. Transmitter frequency, deviation, and power output
should be checked, as should receiver sensitivity, squelch
operation, and audio output. Signaling 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.

3
TK-5810H(B)
4-3. Radio
The universal mount bracket allows the radio to be
mounted in a variety of ways. Be sure the mounting surface
is adequate to support the radio’s weight. Allow sufficient
space around the radio for air cooling. Position the radio
close enough to the vehicle operator to permit easy access
to the controls when driving.
4-4. DC Power and wiring
1. This radio may be installed in negative ground electrical
systems only. Reverse polarity will cause the cable fuse
to blow. Check the vehicle ground polarity before
installation to prevent wasted time and effort.
2. Connect the positive power lead directly to the vehicle
battery positive terminal. Connecting the Positive lead to
any other positive voltage source in the vehicle is not
recommended.
3. Connect the ground lead directly to the battery negative
terminal.
4. The cable provided with the radio is sufficient to handle
the maximum radio current demand. If the cable must be
extended, be sure the additional wire is sufficient for the
current to be carried and length of the added lead.
5. INSTALLATION PLANNING –CONTROL STATIONS
5-1. Antenna system
Control station. The antenna system selection depends
on many factors and is beyond the scope of this manual.
Your KENWOOD dealer can help you select an antenna
system that will best serve your particular needs.
5-2. Radio location
Select a convenient location for your control station radio
which is as close as practical to the antenna cable entry
point. Secondly, use your system’s power supply (which
supplies the voltage and current required for your system).
Make sure sufficient air can flow around the radio and
power supply to allow adequate cooling.
SERVICE
This radio is designed for easy servicing. Refer to the
schematic diagrams, printed circuit board views, and
alignment procedures contained in this manual.
NOTE
You must use KPG-95D version 5.00 or later for this
transceiver. KPG-95D versions earlier than version 5.00
will not work properly.

CIRCUIT DESCRIPTION
1-1. Final Amplifier Circuit (From Power module to
Antenna output): TK-5810H (B)
The transmit signal from the TX terminal (CN1) of the final
unit (X45-380) is amplified by the power module (IC1).
The signal amplified by the power module is divided into
two signal, and further is amplified by the final amplifier
(Q1,Q2). The each signal from Q1 and Q2 is combined.
The combined signal passes through the antenna switch
(D5, D6, D7, D8, D15, D16), CM coupler and low-pass filter,
then it is fed to the antenna.
CM coupler is a line for detecting forward wave and
reflected wave.

Fig. 1 Final amplifier circuit: TK-5810H (B)
Forward wave is detected by D2, and is converted into
DC voltage. The converted DC voltage is fed to the APC
comparator (IC2), and is compared with the PC voltage, then
is output from the OUT-B terminal (pin 7) of IC2 as an APC
voltage. The APC voltage controls the gate voltage of the
power module (IC1) and final amplifier (Q1,Q2), and keeps
transmission output stable.
If an abnormal antenna load is connected, reflected wave
is detected by D3, and output voltage (DC voltage) is fed to
the APC comparator (IC2). The transmission output is
reduced more as this DC voltage rises.
1-2. Temperature Protection Circuit : TK-5810H (B)
To prevent thermal destruction of the power module
(IC1) and final amplifier (Q1,Q2), this circuit reduces APC
voltage when temperature of the power module (IC1) and
final amplifier (Q1,Q2) rises.
The CPU (IC703) detects temperature with the
thermistor (TH1,TH3) and controls reference voltage to the
APC circuit.
