2.2 Replacing the Fuse

The fuse (5A) in the power cable protects the equipment against reverse polarity of ship's
mains and equipment fault. If the fuse blows, find the cause before replacing it.
WARNING
Do not open the equipment.
Hazardous voltage which can
cause electrical shock exists
inside the equipment. Only
qualified personnel should
work inside the equipment.

Check point
The LCD will, in time,
accumulate a coating of dust
which tends to dim the
picture.
Check for tight connection
and corrosion. Clean if
necessary.
CAUTION
Use the proper fuse.
Use of a fuse of the wrong amperage will
damage the equipment and void the
warranty.
Action
Wipe the LCD gently with a soft
cloth. Do not use commercial
cleaners to clean the LCD; they
can remove paint and markings.
If any part is corroded, contact
your dealer about replacement.
