4.2 Replacing the Fuse
The 5A fuse (Type: FGBO-A 125V 5A PBF, Code No. 000-155-853-10) in the snap-in fuse holder
on the power cable protects the equipment from equipment fault and reverse polarity of the ship's
mains. If the equipment cannot be powered, the fuse may have blown. Find out the cause for
blown fuse before replacing it. If the fuse blows again after replacement, contact a FURUNO agent
or dealer for advice.
