THANK YOU!

FEATURES

We are grateful you decided to purchase this
KENWOOD FM transceiver. This series of mobile
transceivers was developed to satisfy the requirement
for a compact rig that’s simple to operate yet contains
numerous sophisticated features. The dual band
operation will be appreciated by hams who want access
to VHF and UHF bands with a transceiver smaller than
some single banders.

KENWOOD believes that the compact size, coupled with
the reasonable cost, will meet your satisfaction.

MOBILE INSTALLATION

2

3

Install the transceiver in a safe, convenient position
inside your vehicle that minimizes danger to your

4

passengers and yourself while the vehicle is in motion.

5

For example, consider installing the transceiver under
the dash in front of the passenger seat so that knees or

6

legs will not strike the radio during sudden braking of

7

your vehicle. Try to pick a well-ventilated location that is
shielded from direct sunlight.

Use the supplied mounting bracket to install the
transceiver inside your vehicle. To enjoy the best
viewing angle, you can position the transceiver in the
bracket in a number of ways as shown below.

2

■ Installation Steps

1 Install the mounting bracket in the vehicle using

the supplied flat washers and self-tapping screws.
There are 4 washers and 4 screws supplied.

• The bracket can be mounted with the bracket
opening for the transceiver facing down for
underdash mounting, or with the opening facing up.

• The bracket must be installed so that the 4 screw
holes on the edge of each bracket side are facing
forward.

2 Position the transceiver, then insert and tighten

the supplied hexagon SEMS screws and washers.
There are 2 screws and 2 washers supplied for
each side of the bracket.

• Double check that all hardware is tightened to
prevent vehicle vibration from loosening the bracket
or transceiver.

SEMS screw

DC POWER CABLE CONNECTION

LOCATE THE POWER INPUT CONNECTOR AS CLOSE TO THE
TRANSCEIVER AS POSSIBLE.

■ Mobile Operation

The vehicle battery must have a nominal rating of 12 V.
Never connect the transceiver to a 24 V battery. Be
sure to use a 12 V vehicle battery that has sufficient
current capacity. If the current to the transceiver is
insufficient, the display may darken during transmission,
or transmit output power may drop excessively.

1 Route the DC power cable supplied with the

transceiver directly to the vehicle’s battery
terminals using the shortest path from the
transceiver.

• If using a noise filter, it should be installed with an
insulator to prevent it from touching metal on the
vehicle.

• It is not recommended to use the cigarette lighter
socket since some cigarette lighter sockets introduce
an unacceptable voltage drop.

• The entire length of the cable must be dressed so it
is isolated from heat, moisture, and the engine
secondary (high voltage) ignition system/ cables.

2 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.

3 To prevent the risk of short circuits, disconnect

other wiring from the negative (–) battery terminal
before connecting the transceiver.

4 Confirm the correct polarity of the connections,

and attach the power cable to the battery
terminals; 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. In
particular, never remove the fuse holders from the
cable.

Note:

◆

For your transceiver to fully exhibit its performance capabilities,
the following optional power supply is recommended:
PS-33 (20.5 A, 25% duty cycle).

◆

Before connecting the DC power supply to the transceiver, be
sure to switch the transceiver and the DC power supply OFF.

◆

Do not plug the DC power supply into an AC outlet until you
make all connections.

■ Replacing Fuses

If the fuse blows, determine the cause then correct
the problem. After the problem is resolved, replace
the fuse. If newly installed fuses continue to blow,
disconnect the power cable and contact your dealer
or nearest Service Center for assistance.

CAUTION:

RATING.

Note:

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 transceiver under these conditions.

ONLY USE FUSES OF THE SPECIFIED TYPE AND

If you use the transceiver for a long period when the vehicle

A02

ANTENNA CONNECTION

Before operating, you must first install an efficient,
well-tuned antenna. The success of your installation will
depend largely on the type of antenna and its correct
installation. The transceiver can give excellent results if
the antenna system and its installation is given careful
attention.

You should choose a 50 Ω impedance antenna to match
the transceiver input impedance. Use low-loss coaxial
feed line that also has a characteristic impedance of
50 Ω. Coupling the antenna to the transceiver via feed
lines having an impedance other than 50 Ω 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 TRANSCEIVER.
ALWAYS CONNECT THE ANTENNA TO THE TRANSCEIVER
BEFORE TRANSMITTING.

◆

ALL FIXED STATIONS SHOULD BE EQUIPPED WITH A
LIGHTNING ARRESTER TO REDUCE THE RISK OF FIRE,
ELECTRIC SHOCK, AND TRANSCEIVER DAMAGE.

OPERATING BASICS

SWITCHING POWER ON/OFF

1 Switch ON the DC power supply.

• If operating mobile, skip this step.

2 Press the (POWER) switch to switch ON the

transceiver.

3 To switch OFF the transceiver, press the (POWER)

switch again.

• In a fixed installation, after the transceiver has been
switched ON, it can then be switched OFF or ON by
using only the power switch on the DC power supply.

ADJUSTING VOLUME

Turn the VOL control clockwise (or counterclockwise) to
increase (or decrease) the audio level.

ADJUSTING SQUELCH

The purpose of the Squelch function is to silence
background noise output from the speaker (squelch
closed) when no signals are present. When the squelch
level is set correctly, you will hear sound (squelch
opened) only while a station is actually being received.

Turn the SQL control to just eliminate the background
noise when no signal is present.

• As you turn the control clockwise, stronger signals are
required to open the squelch.

Note:

The point at which ambient noise on a frequency just disappears,

called the squelch threshold, depends on the frequency.

•To change frequencies in steps of 1 MHz, press
[MHz] first. Pressing [MHz] again cancels the
1 MHz function.

•To change frequencies in steps of 10 MHz, press

[F]

+[MHz] first; do not press

1 second. Pressing
pressing [MHz] starts the 1 MHz function.

Note:

If you cannot select a particular frequency, you need to
change the frequency step size. See “CHANGING FREQUENCY

■ Microphone [UP]/ [DWN] Buttons

Using Mic [UP]/ [DWN] for frequency selection is
useful when mobiling or any time you are not
immediately in front of the transceiver.

Press Mic [UP] or [DWN] once to change the
frequency by one step in the direction indicated by
the button.

• Pressing and holding the button causes the frequency to

step repeatedly. Release it to stop the frequency
change.

•To change frequencies in steps of 1 MHz (or 10 MHz),

[F]

press [MHz] (or

MC-53DM

+[MHz]) first.

16

TRANSMITTING

1 When ready to begin transmitting, press and hold Mic

[PTT] and speak in a normal tone of voice.

• “ON AIR” and the RF power meter appear.

• Speaking too close to the microphone, or too loudly,
may increase distortion and reduce intelligibility of your
signal at the receiving station.

• The RF power meter shows the relative transmit output
power.

2 When you finish speaking, release Mic [PTT].

MC-53DM

■ Selecting Output Power

It’s wise, and required by law, to select the lowest
power that allows reliable communication. If
operating from battery power, lower transmit power
will give you more operating time before a charge is
necessary. Reducing power lowers the risk of
interfering with others on the band.

Press

[LOW]

to select high (“H”), medium (“M”), or

low (“L”) power. The default is high.

CAUTION:

◆

DO NOT TRANSMIT WITH HIGH OUTPUT POWER FOR
EXTENDED PERIODS. THE TRANSCEIVER MAY OVERHEAT
AND MALFUNCTION.

◆

CONTINUOUS TRANSMISSION CAUSES THE HEAT SINK TO
OVERHEAT. NEVER TOUCH THE HEAT SINK WHEN IT MAY BE
HOT.

Note:

When the transceiver overheats because of ambient high
temperature or continuous transmission, the protective circuit may
function to lower transmit output power.
