SAFETY PRECAUTIONS
It is important that the operator understands and is
aware of hazards common to the operation of any
radiotelephone.
WARNING!
1 EXPLOSIVE ATMOSPHERES
(GASES, DUST, FUMES, ETC.)
Turn off and do not operate the radiotelephone while
taking on fuel, or while parked in gasoline service
stations. Do not carry spare fuel containers in the trunk
of your vehicle if the radiotelephone is mounted in the
trunk area.
2 INJURY FROM RADIO FREQUENCY
TRANSMISSIONS
Do not operate the radiotelephone when anyone is
touching the antenna, or when anyone is standing within
two to three feet of the antenna, to avoid the possibility
of radio frequency burns or related physical injury.
3 DYNAMITE BLASTING CAPS
Transmitter operation can cause dynamite blasting caps
to explode if you operate within 500 feet of the blasting
caps. Turn off and do not operate the radiotelephone in
an area where blasting is in progress, or where “TURN
OFF TWO-WAY RADIO” signs have been posted. If
you are transporting blasting caps in your vehicle, make
certain they are carried in a closed metal box having a
padded interior. Do not transmit during the time that the
caps are being placed into or removed from this
container.
IMPORTANT NOTICE
Government law prohibits the operation of unlicensed
radio transmitters within the territories under
government control. Illegal operation is punishable by
fine or imprisonment or both.
Refer service to a qualified licensed or certified
technician only.
INTRODUCTION
All KENWOOD radiotelephones incorporate the latest in
advanced technology, providing communications that
_can be counted on to keep vehicles and personnel
operating at peak efficiency.
The easy-to-operate TRC-80 radiotelephone continues
the KENWOOD tradition of dependable
communications. When combined with the optional
KPE-1 Selective Call Unit, the TRC-80 allows full
flexibility for signaling and communicating with specific
stations or groups of stations.
SUPPLIED ACCESSORIES
Note: The following instructions are for use by your KENWOOD
Dealer only (either an authorized KENWOOD service facility or the
factory).
Carefully unpack the radiotelephone. It is
recommended that you identify the items listed and
check them off before discarding the packing material.
If any damage has occurred to the equipment during
shipment, file a claim with the carrier immediately.

BASE STATION INSTALLATION
ANTENNA CONNECTION
The type of the antenna system, consisting of the
antenna, ground, and feed line, will greatly affect the
successful performance of the radiotelephone. Use a
properly adjusted 50 Q antenna of good quality to let
your radiotelephone perform at its best. Use a
good-quality 50 Q coaxial cable and a first-quality
connector for the connection. Match the impedance of
the coaxial cable and antenna so that the SWR is 1.5:1
or less. All connections must be clean and tight.
While the radiotelephone’s protection circuit will activate
if the SWR is greater than 2.5:1, do not rely on
protection to compensate for a poorly functioning
antenna system. High SWR will cause the transmit
output to drop, and may lead to radio frequency
interference to consumer products such as stereo
receivers and televisions. You may even interfere with
your own radiotelephone. Reports that your signal is
garbled or distorted, especially at peak modulation, may
indicate that your antenna system is not efficiently
radiating the radiotelephone’s power. If you feel a tingle
from the radiotelephone’s cabinet or the microphone’s
metal fittings when you modulate, you can be certain
that, at the least, your coax connector is loose at the
rear of the radio and, at the worst, your antenna system
is not efficiently radiating power.
CAUTION:
@ = Transmitting without first connecting an antenna or other matched
load may damage the radiotelephone. Always connect the
antenna to the radiotelephone before transmitting.
@ Usea lightning arrestor to prevent fire, electric shock, or damage
to the radiotelephone.
GROUND CONNECTION
At the minimum, a good DC ground is required to
prevent such dangers as electric shock. For superior
communications results, a good RF ground is required,
against which the antenna system can operate. Both of
these conditions can be met by providing a good earth
groundior your station. Bury one or more ground rods,
or a large copper plate under the ground, and connect
this to the radiotelephone GND terminal. Use heavy
gauge wire or a copper strap, cut as short as possible,
for this connection. All connections must be clean and
tight.
To antenna
DC POWER SUPPLY CONNECTION
In order to use this radiotelephone, you will need a
separate 13.6 V DC power supply that must be
purchased separately. DO NOT directly connect the
radiotelephone to an AC outlet! Use the supplied DC
power cable to connect the radiotelephone to a
regulated power supply. Do not substitute a cable with
smaller gauge wires. The current capacity of your
power supply must be 20.5 A or more.
CAUTION:
@ Before connecting the DC power supply to the radiotelephone, be
sure to switch the radiotelephone and the DC power supply OFF.
@ Donot plug the DC power supply into an AC outiet until you
make all connections.
First connect the DC power cable to the regulated DC
power supply and check that polarities are correct
(Red: positive, Black: negative). Then connect the
connectorized end of the DC power cable to the
DC 13.6 V power connector on the radiotelephone Rear
Panel. Press the DC power cable connector firmly into
the connector on the radiotelephone until the locking tab
clicks.
@ Replacing Fuses
If the fuse blows, determine the cause then correct
the problem. After the problem is resolved, only then
replace the fuse. If newly installed fuses continue to
blow, disconnect the power plug and contact your
Dealer for assistance.

MOBILE INSTALLATION
install
the
radiotelephone
in
a
safe,
convenient
position
inside
your
vehicle
that
minimizes
danger
to
your
passengers
and
yourself
while
the
vehicle
is
in
motion.
For
example,
consider
installing
the
radiotelephone
under
the
dash
in
front
of
the
passenger
seat
so
that
knees
or
legs
will
not
strike
the
radiotelephone
during
sudden
braking
of
your
vehicle.
Try
to
pick
a
well-
ventilated
location
that
is
shielded
from
direct
sunlight.
ANTENNA CONNECTION
Before operating mobile, you must first install an
efficient, well-tuned antenna. The success of your
mobile installation will depend largely on the type of
antenna
and
its
correct
installation.
The
radiotelephone
can
give
excellent
results
if
the
antenna
system
and
its
installation is given careful attention.
Your
choice
of
antenna
should
have
a
50
Q
impedance
to
match
the
radiotelephone
input
impedance.
Use
low-
loss
coaxial
feed
line
that
also
has
a
characteristic
impedance
of
50
.
Coupling
the
antenna
to
the
radiotelephone
via
feed
lines
having
an
impedance
other
than
50
Q
reduces
the
efficiency
of
the
antenna
system,
and
can
cause
interference
to
nearby
broadcast
television
receivers,
radio
receivers,
and
other
electronic
equipment.
CAUTION:
Transmitting
without
first
connecting
an
antenna
or
other
matched
load
may
damage
the
radiotelephone.
Always
connect
the
antenna
to
the
radiotelephone
before
transmitting.
DC POWER CABLE CONNECTION
Route
the
DC
power
cable
supplied
with
the
radiotelephone
directly
to
the
vehicle’s
battery
terminals
using
the
shortest
path
from
the
radiotelephone.
If
using
a
noise
filter,
it
should
be
installed
with
an
insulator
to
prevent
it
from
touching
metal
on
the
vehicle.
Itis
not
recommended
to
use
the
cigarette
lighter
socket
since
some
cigarette
lighter
sockets
introduce
an
unacceptable
voltage
drop.
To prevent the risk of short circuits, disconnect other
wiring from the negative (-) battery terminal before
connecting the radiotelephone. Confirm the correct
polarity
of
the
connections
before
attaching
the
power
cable; red connects to the positive (+) terminal, black
connects to the negative (-) terminal. Use the full
length of the cable without cutting off excess even if the
cable is longer than required. !n particular, never
To antenna
remove the fuse holders from the cable. After
completing radiotelephone connections to the battery,
then reconnect any wiring removed from the negative
terminal.
If the power cable must be routed through a hole in the
vehicle chassis or body, for example in the firewall at the
front of the passenger compartment, use a rubber
grommet to protect the cable from abrasion. The entire
length of the cable must be dressed so it is isolated from
heat and moisture. After the cable is in place, wind
heat-resistant tape around the fuse holder to protect it
from moisture. Tie down the full run of cable.
The vehicle battery must have a nominal rating of 12 V.
Never connect the radiotelephone to a 24 V battery. Be
sure to use a 12 V vehicle battery that has sufficient
current capacity. If the current to the radiotelephone is
insufficient, the Display may darken during transmission,
or transmit output power may drop excessively.
Only after completing the installation, connect the
radiotelephone’s power supply connector to the DC
power cable. Press the connectors firmly together until
the locking tab clicks.
Note: If you use the radiotelephone for a long period when the
vehicle battery is not fully charged, or when the engine is OFF, the
battery may become discharged, and will not have sufficient reserves
to start the vehicle. Avoid using the radiotelephone under these
conditions.
@ Replacing Fuses
If the fuse blows, determine the cause then correct
the problem. Refer to additional information
including fuse ratings on page 2.
CAUTION: Replace blown fuses only after investigating and
correcting the cause of the failed fuse. Always replace a blown
fuse by a new fuse with the specified ratings.
GROUND CONNECTION
For a mobile installation, it is extremely important to
securely connect a low-resistance ground strap from the
radiotelephone GND terminal to the metal vehicle
chassis. This connection is necessary since mobile
antennas are physically small and, therefore, less
efficient than larger base station antennas. If a strap is
not available, a large gauge copper wire is suitable.
Always clean paint or dirt from the vehicle connection
point and expose bare metal before connecting the
ground. A high-quality ground installation significantly
improves the performance of a mobile antenna.

KENWOOD
ADJUSTING SQUELCH
The purpose of squelch is to silence audio output from
the speaker when no signals are present. Setting the
squelch threshold too high causes the squelch to
remain closed while a weak signal is present. Setting
the threshold too low allows noise to be heard between
transmissions from other stations.
Turn the SQUELCH control to just eliminate the
background noise when no signal is present. If signals
are weak, set the control fully counterclockwise.
