Introduction
Features of this transceiver
144/430 MHz dual-band transceiver equipped with standard C4FM digital
communication modulation
Clear audio and data communication are achieved using the digital modulation
functions
With the DG-ID (Digital Group ID), the Group Monitor (GM) feature enables automati-
cally locating, and communicating with other stations that have the same DG-ID num-
ber within contact range, by utilizing a matching group ID number from 00 to 99
The Digital Personal ID (DP-ID) feature may communicate only by the transceivers
registered the individual ID information that is different for each transceiver included in
the transmission radio wave of C4FM digital communication

Wide-band receives in the 108 MHz to 999 MHz range (air band, information wireless band)
Transmit power 50 watts with cooling fan
The dot matrix LCD is mounted on the front panel
500 memory channels in the A-band and 500 channels in the B-band

main body to rise and result in burns
and failures due to overheating.
Do not dismantle or modify the
device.
This may result in injury, electric shock
and equipment failure.
Do not handle the power plug and
connector etc. with wet hands. Also
do not plug and unplug the power
plug with wet hands.
This may result in injury, liquid leak,
electric shock and equipment failure.
When smoke or strange odors are
emitted from the radio, turn off the
power and disconnect the power
cord from the socket.
This may result in fire, liquid leak,
overheating, damage, ignition and
equipment failure. Please contact our
company amateur customer support or
the retail store where you purchased
the device.
Keep the power plug pins and the
surrounding areas clean at all times.
This may result in fire, liquid leak,
overheating, breakage, ignition etc.
Do not place the device in areas
that may get wet easily (e.g. near a
humidifier).
This may result in fire, electric shock
and equipment failure.
When connecting a DC power cord,
pay due care not to mix up the
positive and negative polarities.
This may result in fire, electric shock
and equipment failure.
Do not use DC power cords other
than the one enclosed or specified.
This may result in fire, electric shock
and equipment failure.
Do not bend, twist, pull, heat
and modify the power cord
and connection cables in an
unreasonable manner.
This may cut or damage the cables
and result in fire, electric shock and
equipment failure.
Do not pull the cable when plugging
and unplugging the power cord and
connection cables.
Please hold the plug or connector when
unplugging. If not, this may result in fire,
electric shock and equipment failure.
KWhen transmitting, keep the
antenna at least 1.8 m (VHF) or 2.2 m
(UHF) away from your body.
Do not use modified or damaged
antennas.

7
Before Use
Safety Precautions (make sure to read these)
Do not use the device when the
power cord and connection cables
are damaged, and when the DC
power connector cannot be plugged
in tightly.
Please contact our company amateur
customer support or the retail store
where you purchased the device as this
may result in fire, electric shock and
equipment failure.
Never cut off the fuse holder of the
DC power cord.
This may cause short-circuiting and
result in ignition and fire.
Do not use fuses other than those
specified.
Doing so may result in fire and
equipment failure.
Do not allow metallic objects such
as wires and water to get inside the
product.
This may result in fire, electric shock
and equipment failure.
Refrain from using headphones and
earphones at a loud volume.
Continuous exposure to loud volumes
may result in hearing impairment.
Disconnect the power cord
and connection cables before

Precautions on installation
Note the following when installing the transceiver.
Do not install the transceiver in a place where it would be exposed to direct sunlight,
high temperatures, excessive humidity, dusty conditions, or extreme vibrations.
Install the transceiver in a well-ventilated position, so that heat dissipation is not
hindered, because the heat sinks will become hot when the transceiver is run for an
extended period of time.
Do not place any objects on the transceiver.
Do not attempt to lift the front panel by holding onto just the knob or control cable.
This transceiver requires a 13.8 V DC power supply.
When using this transceiver in a mobile unit, ensure that the car battery is a 12 V
type. Never connect this transceiver to a 24 V battery of a large vehicle.
Never connect the transceiver to a 100 V AC power source.
Heed caution as hum and noise may be introduced, depending on the installation
conditions of the external power source.
Install the transceiver as far away as possible from TVs and radios. Failing to do so
may result in noise interference such as broadcast interference (BCI) or television
interference (TVI) from radios and TVs respectively.
Never attempt to install this transceiver near indoor antenna elements.

About the antenna
The antenna is an extremely important part for both transmitting and receiving. The
antenna type and its inherent characteristics determine whether the performance of the
transceiver can be fully realized. As such, please note the following:
Use an antenna that is suitable for the installation conditions and application
objective.
Use an antenna that is suitable for the operating frequency band.
Use an antenna and a coaxial cable with a characteristic feed point impedance of
50Ω.
Adjust the VSWR (Voltage Standing Wave Ratio) until it is 1.5 or less for an antenna
with an adjusted impedance of 50Ω.
Keep the coaxial cable routing length as short as possible.
Installing the antenna
●Antenna installation in a mobile unit
Install the antenna base to the rear of the car (rear bumper, trunk, rear gate, etc.) and
then attach the antenna to the base.
Cautions
zVerify that the antenna base is securely grounded to the car body.
zWhen using a coaxial cable included with a commercially-available on-vehicle antenna, lay the
cable in a way to keep it as short as possible.
zDo not allow rain water or moisture to penetrate the entrance of the cable or connectors when
routing the coaxial cable inside the vehicle.
●Antenna installation when using a fixed station
For use in an outdoor setting, there are omni-directional antennas and a variety of
directional antennas.
•Omni-directional antennas such as the GP (Ground Plane) antenna are suitable for
communications with a local station or mobile stations in all directions.
•Directional antennas such as the Yagi antenna are suitable for communications with a
specific station or a remote station in a specific direction.
Cautions
zCreate a loop (slack) in the coaxial cable directly underneath the antenna and fasten the coaxial
cable so that the weight of the cable does not pull on the antenna.
