6.2 How to Replace the Fuse
A fuse is located on the front of the processor unit. The fuse protects the equipment
from reverse polarity of the ship’s mains and equipment fault. If a fuse blows, find the
cause before replacing it. Use the correct fuse. Using the wrong fuse will damage the
equipment and void the warranty.
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.
