5-1
This chapter tells you how to keep your ra-
dar in good working order. Before reviewing
this chapter please read the safety informa-
tion which follows.
Turn off the power before
performing any maintenance or
troubleshooting procedure.
DANGER
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 scanner emits high frequency
radio radiation which can be harmful,
particularly to your eyes.
Never look directly into the scanner 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 scanner unit.
5.1 Preventive Maintenance
Regular maintenance is important for good
performance. 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 estab-
lished 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
equipment against reverse polarity of ship's
mains, overcurrent, and equipment fault. If
the fuse blows, find the cause before replac-
ing it. Never use an incorrect fuse - serious
damage to the equipment may result and void
the warranty.
12V: 10A fuse
24/32V: 5A fuse
