How to Replace 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 power

supply. If the equipment cannot be powered, the fuse may have blown. Find out the cause for the

blown fuse before replacing it. If the fuse blows again after replacement, contact a FURUNO agent

or dealer for instructions.
