5. MAINTENANCE & TROUBLESHOOTING

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.

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 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

CAUTION

Use the proper fuse.

Use of a wrong fuse can result in equipment damage.
