MOBILE INSTALLATION
nTX/ RX Unit Installation
Select a safe, convenient location inside your vehicle that will minimize danger
to your passengers and yourself while the vehicle is in motion. 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 a pick well-ventilated location that is shielded from direct sunlight.
Note: You may experience interference on your GPS receiver when using in or around 438.8
MHz (A band) and/or 443.8 MHz (B band). To eliminate the interference, ensure that the
transceiver is installed at a location separate from your GPS receiver.
1Install the mounting bracket in the vehicle using the supplied self-tapping
screws and flat washers (4 of each are supplied).
• The bracket can be mounted with the bracket opening facing down, for under dash
mounting, or facing up.
• The bracket must be installed so that the 3 screw slots on the edge of each bracket
side are facing the back.
2Position the transceiver, then insert and tighten the supplied hexagon
SEMS screws and flat washers (4 of each are supplied, 2 for each side of
the bracket).
• Ensure that all hardware is tightened, to prevent vehicle vibration from
loosening the bracket or TX/ RX unit.
• Set an appropriate angle for the TX/ RX unit, using the 3 screw slots on
the rear edge of each bracket side.

nOperation Panel Installation
1Clean and dry the installation location.
Do not install the bracket close to an air bag.
2Remove the release paper from the base
of the panel bracket, then secure it in
place using the 3 supplied self-tapping
screws.
• Allow the panel to set for a while, to
ensure it remains fast. Otherwise,
vibrations may occur.
• After removing the release paper, it cannot
be reused.
3Attach the panel holder to the panel
bracket using the 2 supplied SEMS
screws.
4Attach the operation panel to the panel
holder so that it locks in place.
nPower Cable Connection
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 the transmit output power may drop excessively. Never
connect the transceiver to a 24 V battery.

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.
1Route the DC power cable supplied with the transceiver directly to the
vehicle’s battery terminals using the shortest path from the transceiver.
• When using a noise filter, it should be installed with an insulator to prevent it from
touching metal on the vehicle.
• We do not recommend using a cigarette lighter socket as some cigarette lighter
sockets introduce an unacceptable voltage drop.
• If the power cable must be routed through a hole in the vehicle chassis or body,
for example in the fire wall 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 fire wall.
• 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.
2After 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.
3To prevent the risk of short circuits, disconnect other wiring from the
negative (–) battery terminal before connecting the transceiver.

recommended current capacity of the power supply is 13 A.
Note: Do not plug the DC power supply into an AC outlet until you make all connections.
1Ensure that the transceiver and DC power supply are both OFF.
2Connect the DC power cable to the regulated DC power supply and ensure
that the polarities are correct (Red: positive, Black: negative).
• Use the supplied DC power cable to connect the transceiver to a regulated
power supply. Do not directly connect the transceiver to an AC outlet.
• Do not substitute the cable with smaller gauge wires.
3Connect the DC power cable to the transceiver.
• Press the connectors firmly together until the locking tab clicks.
Note: For your transceiver to fully exhibit its performance capabilities, we recommend using
an optional PS-33 (20.5 A, 25% duty cycle) power supply.

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 are given careful attention.
Use a low-loss coaxial feed line that also has a characteristic impedance of
50 Ω, to match the transceiver input impedance. 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.
uTransmitting without first connecting an antenna or other matched load may damage the
transceiver. Always connect the antenna to the transceiver before transmitting.
uAll fixed stations should be equipped with a lightning arrester to reduce the risk of fire, electric
shock, and/or transceiver damage.
