3-2-2. Mobile Installations
Install in the safest and most accessible
location.
A. Battery Connections
Connect the power cable directly to the battery
terminals.Use of the cigarette lighter socket will lead
to poor connection, and will result in poor
performance. Pay close attention to the polarity of
the cables when connecting them to the battery.
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.
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).

C. Grounding for mobile installation
When the transceiver is installed in a car, use a
short whip antenna.
Grounding is very important when using a whip
antenna. If the grounding is poor, a good SWR value
will not be obtained.

To antenna terminal
Since an HF antenna is large and heavy, it must be installed to with-
stand high wind stress.
