■ Installation Steps
MOBILE INSTALLATION
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.
Install the transceiver 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 transceiver under the dash in front of
the passenger seat so that knees or legs will not strike the
radio during sudden braking of your vehicle. Try to pick a
well-ventilated location that is shielded from direct sunlight.
•
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.
■ Installation Example
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.
Flat washer
Self-tapping

DC POWER CABLE CONNECTION
1
■ Mobile Operation
3 To prevent the risk of short circuits, disconnect other
wiring from the negative (–) battery terminal before
connecting the transceiver.
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.
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.
1 Route the DC power cable supplied with the
transceiver directly to the vehicle’s battery terminals
using the shortest path from the transceiver.
•
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.
•
•
•
If using a noise filter, it should be installed with an
insulator to prevent it from touching metal on the
vehicle.
Red
It is not recommended to use the cigarette lighter
socket since some cigarette lighter sockets introduce
an unacceptable voltage drop.
Fuse holder
Black
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.
Dismantle the fuse holder to pass the cable through
the firewall.
5 Reconnect any wiring removed from the negative
terminal.
6 Connect the DC power cable to the transceiver’s
power supply connector.
•
Press the connectors firmly together until the locking
tab clicks.
Press
firmly.
•
The entire length of the cable must be dressed so it is
isolated from heat and moisture.

In order to use this transceiver for fixed station
operation, you will need a separate 13.8 V DC power
supply that must be purchased separately. The
recommended current capacity of your power supply is
12 A.
•
Press the connectors firmly together until the locking
tab clicks.
1 Connect the DC power cable to the regulated DC
power supply and check that polarities are correct
(Red: positive, Black: negative).

Note:
◆
Use the supplied DC power cable to connect the
transceiver to a regulated power supply.
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.
Do not substitute a cable with smaller gauge
wires.

■ Replacing Fuses
ANTENNA CONNECTION
1
If the fuse blows, determine the cause then correct the
problem. After the problem is resolved, then replace the
fuse. If newly installed fuses continue to blow,
disconnect the power cable and contact your dealer or
the nearest Service Center for assistance.
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.
Fuse Current Rating
Fuse Location
Your choice of antenna should have a 50 Ω impedance 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

RATING.
Note: If you use the transceiver 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 transceiver under these conditions.
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

The purpose of squelch is to silence audio output from the
speaker when no signals are present. When squelch is set
correctly, you will hear sound only while a station is actually
being received. The point at which ambient noise on a
frequency just disappears, called the squelch threshold,
depends on the frequency.

■ Selecting Output Power
TRANSMITTING
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.

Repeaters are typically located on a mountain top or other
elevated location. Often they operate at higher ERP
(Effective Radiated Power) than a typical station. This
combination of elevation and high ERP allows
Most Amateur Radio voice repeaters use a separate
receive and transmit frequency. The transmit frequency
may be higher or lower than the receive frequency but the
difference in frequencies will be a standard amount, or
"standard split". You can set a separate receive and
transmit frequency by selecting the offset frequency and
offset direction with respect to the receive frequency.
communications over considerable distances.
6
Repeaters are often installed and maintained by radio
clubs, sometimes with the cooperation of local businesses
involved in the communications industry. During
emergencies, repeater networks can be a valuable aid to
officials responsible for coordinating communications in a
community.
In addition, some repeaters may require the transceiver to
transmit a tone before the repeater can be used. To
transmit this required tone, activate the Tone function and
select a tone frequency. The required tone frequency
depends on the repeater you are accessing.

APPLICATION EXAMPLES
Situation 2:
While operating mobile on the way to work every morning,
you prefer a silent transceiver that does not interrupt the
morning calm. In addition, you feel that a bright display is
a waste of electricity in sunlight.
The following are examples of how you might use
Programmable Memory. These examples may not
represent applications useful to you, but you will
understand the flexibility of this function.
At night when driving home, you realize the Beep function
truly serves a purpose and you acknowledge it is nice to
see a bright display after dark.
Situation 1:
You share your transceiver with other members in your
family or club. However, each individual has personal
preferences for how they like to set various functions. You
have to keep changing many settings each time you use
the transceiver.
Solution:
In two PM channels, store the same operating data such
as frequency, offset, DTSS code, etc., and store different
settings for the Display Dimmer and Beep functions. Then
you can quickly recall the best settings for day or night
operating.
8
Solution:
Because 4 PM channels are available, up to 4 persons can
separately program the transceiver and store their
customized environment. Then each person can quickly
change to his or her favorite settings, simply by recalling a
PM channel.
Situation 3:
You cannot figure out how you can make the transceiver
exit the current mode.
It is too much trouble to change the settings after
somebody else has reconfigured them. So this application
may avoid having a feature-rich transceiver but never using
many useful features.
Solution:
Simply recall PM channel 1 that contains an exact copy of
the transceiver default environment. You will not lose the
contents of any memory channels.

SCAN
Scan is a useful feature for hands-off monitoring of your
favorite frequencies. After becoming comfortable with how
to use all types of Scan, the monitoring flexibility gained will
increase your operating efficiency.
When using with CTCSS and/or DTSS:
•
While using CTCSS, Scan stops and the squelch opens only
when received signals contain the matching CTCSS tone.
•
While using DTSS, Scan stops for any signals received.
However, if the signals do not contain the matching DTSS
code, the squelch does not open.
This transceiver provides the following conventional scans
in addition to “Visual Scan” {page 41} that may be new to
you.
•
When both CTCSS and DTSS are ON, Scan stops for signals
that contain the matching CTCSS tone. However, if the
signals do not contain the matching DTSS code, the squelch
does not open.

■ DTSS and Repeaters
Pressing Mic [PTT] transmits the DTSS signal after a
short delay. When using repeaters with long response
times, this delay helps the repeater avoid losing a
portion of the DTSS code. The delay time is 350 ms
during simplex operation.
When using a transmit offset or a split frequency, you
can select either 350 ms (default) or 550 ms.

PAGE
Page also uses DTMF codes to address specific stations.
When your transceiver transmits a DTMF code, the
squelch of only the transceivers that have the same code
programmed, opens.
PAGE CODE MEMORY
This transceiver has 7 Page code memory channels on
each band. You can select a 3-digit code from among 1000
combinations, 000 to 999 to store in each channel.
Unlike DTSS, Page allows you to choose whether you will
call a single station or a group of stations. In addition,
Page offers the added benefit of identifying who called you.
When you are called with your Station code, the calling
station’s code appears on the display. If called with a
Group code, the Group code appears.
Ch. A
Ch. 0
Stores your Station code.
When called, the calling station's code or the
Group code is automatically stored.
Ch. 1~5 Stores Group codes or Station codes that
you want to call.
Note: Be aware that audible DTMF tones from other transceivers near
you may be picked up by your MC-53DM or MC-45 microphone. If so,
this could prevent the functions described in this chapter from working
correctly.

AUXILIARY FUNCTIONS
AUTOMATIC POWER OFF (APO)
TIME-OUT TIMER (TOT)
Automatic Power Off is a background function that monitors
whether any buttons or keys have been pressed, or whether
the Tuning control has been turned. After 3 hours pass
with no operations, APO turns OFF the power. However,
1 minute before the power turns OFF, "APO" appears and
blinks, and a series of warning tones sound.
It is sometimes necessary or desirable to restrict a single
transmission to a specific maximum time. This feature can
be useful when accessing repeaters to prevent repeater
time-outs, or when trying to conserve battery power.
When TOT times out, the transceiver generates beeps and
automatically returns to receive mode. To resume
transmitting, release and then press Mic [PTT] again.
Note: If the squelch opens or any settings are changed during the 3 hour
period while APO is ON, the timer resets. When the squelch closes or
you stop changing the settings, the timer begins counting again from 0.

Terminal Node Controller (TNC) {page 6}. You can send
Email to far away stations or obtain a variety of information
via your local bulletin boards, or you may enjoy other
Packet applications. Reference material for starting Packet
operation should be available at any store that handles
Amateur Radio equipment.
Select 1200 bps or 9600 bps for the data transfer rate,
depending on the type of your TNC.
1200 bps:
The Transmit data input (PKD) sensitivity is 40 mVP-P, and
the input impedance is 10 kΩ. This is suitable for a typical
1200 bps TNC.
9600 bps:
ACTIVATING DATA TX/RX BAND
The Transmit data input (PKD) sensitivity is 2 VP-P, and the
input impedance is 10 kΩ. This is suitable for most
9600 bps TNCs. Select 9600 bps if using a TNC with dual
speed capability that only has a 2 VP-P output.
If you prefer, you can send or receive data using a RX-only
band where “PTT” is invisible. The band with “PTT” is used
for voice communications.

TROUBLESHOOTING
The problems described in this table are commonly encountered operational malfunctions. These types of difficulties are
usually caused by improper hook-up, accidental incorrect control settings, or operator error due to incomplete programming.
These problems are usually not caused by circuit failure. Please review this table, and the appropriate section(s) of this
instruction manual, before assuming your transceiver is defective.
Note: When 2 frequencies are received in the same band and these frequencies have relationships per the equation below or other similar relationships,
an internal heterodyne may be heard. This is not a defect.
VHF/UHF mode: (UHF receive frequency – 45.05 MHz) x 2 – (VHF receive frequency + 38.85 MHz) x 4 = 38.85 MHz or 45.05 MHz
(UHF receive frequency – 45.05 MHz) – (VHF receive frequency + 38.85 MHz) x 2 = 38.85 MHz
VHF/VHF mode: (VHF receive frequency on the UHF band + 45.05 MHz) x 5 – (VHF receive frequency on the VHF band + 38.85 MHz) x 5 = 38.85 MHz or 45.05 MHz
(VHF receive frequency on the UHF band + 45.05 MHz) x 4 – (VHF receive frequency on the VHF band + 38.85 MHz) x 4 = 38.85 MHz
(VHF receive frequency on the VHF band + 38.85 MHz) – (VHF receive frequency on the UHF band + 45.05 MHz) x 0.75 = 38.85 MHz
UHF/UHF mode: (UHF receive frequency on the VHF band – 38.85 MHz) x 3 – (UHF receive frequency on the UHF band – 45.05 MHz) x 3 = 38.85 MHz or 45.05 MHz
(UHF receive frequency on the VHF band – 38.85 MHz) x 4 – (UHF receive frequency on the UHF band – 45.05 MHz) x 4 = 38.85 MHz or 45.05 MHz
