4-2 CONNECTION
4-2-1 Mobile Installations
Cautions :
1. Before installing the power cable, be sure to
remove the negative lead from the battery for
safety.
2. After installation and wiring, be sure to double
check for correct installation before reconnecting
the negative lead to the battery terminal.
3. If the fuse opens, be sure to check that each
conductor has not been damaged by short
circuiting, etc. Then replace with a new fuse of
the same rating.
4. After completing the wiring, wrap the fuse holder
with heat resistant tape to protect against heat
and moisture.
5. Do not remove the fuse even if the power cable is
too long.

A. Battery Connections
Connect the power cable directly to the battery
terminals. Using of the cigarette lighter socket will lead
to a poor connection, and will result in poor
performance. Pay close attention to the polarity of the
cables when connecting them to the battery.
Make sure the positive (+) and negative (—) lead polarity is correct
when connecting to the battery.

B. Ignition Noise
This transceiver has been designed to suppress ignition
noise; however, if excessive noise is present, it may be
necessary to use suppressor spark plugs (with resistors).
