Initial Installation

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
for assistance.

Only use fuses of the specified type and rating, otherwise the

transceiver could be damaged.
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 in these conditions.
Power supply voltage Display
After connecting the transceiver to the power supply, the supply voltage
can be displayed on LCD by pressing the
key.
MONI
The display immediately changes as the voltage supply changes, It
also displays voltage during transmission.
The transceiver will return to its normal operation when the power is
switched ON or repeat above operation.

The range of displayed voltage is only from 7V to16V DC. Because the
displayed value is estimated, please use a voltmeter when a more precise

reading is desired.
Antenna Connection
Before operating, install an efficient, well-tuned antenna. The success
of your installation will depend on the type of antenna and its correct
installation.
Use a 50Ω impedance antenna and low-loss coaxial feed-line that
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 50Ω reduces the efficiency of the antenna
system and can cause interference to nearby televisions, radio receivers
and other electronic equipment.
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.
