6. MAINTENANCE, TROUBLESHOOTING
6-4
For configurations with the Deicer Kit installed
Note: This fuse is located inside the scanner unit.
6.3 Life Expectancy of Major Parts
This radar has consumable parts, and the table that follows shows the estimated life
expectancy for the consumable parts. Life expectancy estimates are based on use un-
der normal conditions. Request a FURUNO agent or dealer to replace the consumable
parts, to get the best performance and longest possible life from the equipment.
Note: The magnetron is a consumable item. The effectiveness of your magnetron will
decrease over time, causing lower-than-normal signal strength and loss of echoes.
Magnetrons should be changed regularly. The table above shows the typical life-span
of a magnetron used under normal conditions.
6.4 Trackball Maintenance
If the cursor skips or moves abnormally, clean the trackball using the procedure below.
1. Turn the retaining ring counterclockwise 45° to
unlock it.
2. Remove the retaining ring and ball.
3. Clean the ball with a soft, lint-free cloth, then
blow carefully into the ball-cage to dislodge
dust and lint.
4. Look for a build-up of dirt on the metal rollers.
If dirty, clean the rollers using a cotton swab
moistened lightly with isopropyl-rubbing alcohol.
5. Make sure that fluff from the swab is not left on the rollers.
6. Replace the ball and retaining ring. Be sure the retaining ring is not inserted re-
versely.
