5. MAINTENANCE & TROUBLESHOOTING
This chapter tells you how to keep your radar
in good working order. Before reviewing this
chapter please read the safety information which
follows.
DANGER
Turn off the power before
performing any maintenance or
troubleshooting procedure.
Hazardous voltages can shock, burn or cause death.
Only qualified personnel totally famillier with electrical
circuits should work inside the units.
RF RADIATION HAZARD
The radar antenna emits high frequency
radio radiation which can be harmful,
particularly to your eyes.
Never look directly into the antenna from a distance of
less than two feet when the radar is in operation as
you could injure the cornea of your eyes. Always
make sure the radar is set to stand-by or is turned off
before starting work on the antenna unit.

5.1 Preventative Maintenance
Regular maintenance is important for good per-
formance. Always keep the equipment as free
as possible from dirt, dust, and water splashes.
Make sure all screws securing the components
are properly tightened.
A maintenance program should be established
and should at least include the items listed in
table 5-1.
5.2 Replacing the Fuse
The fuse in the power cable protects the equip-
ment against reverse polarity or ship's mains,
overcurrent, and equipment fault. If the fuse
blows, find the cause before replacing it. Never
use an incorrect fuse – serious damage to equip-
ment may result and void the warranty.
12 V:
10 A fuse
24-32 V: 5 A fuse
