10.2 Fuse Replacement
The fuse on the power cable protects the equipment from overcurrent and equipment
fault. If the fuse blows, find the cause before you replace the fuse. Use the correct
fuse. A wrong fuse can damage the equipment.

When the life of the magnetron is reached, the targets do not appear on the display.
If long-range performance appears to have decreased, contact a FURUNO agent or
dealer about replacement of the magnetron. The magnetron changes with the type of
antenna unit.
Use the correct fuse.
