This chapter tells you how to keep your radar

in good working order. Before reviewing this

chapter please read the safety information 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 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.
