Regular maintenance is essential for good performance. Check the items listed in the table below
monthly to help keep your equipment in good shape for years to come.
4.2 Replacing the fuse

Code No. 000-155-850-10) in the snap-in fuse holder
on the power cable protect the equipment from equip-
ment fault and reverse polarity of the ship's mains. If
the equipment cannot be powered, a fuse may have
blown. Find out the cause for blown fuse before re-
placing a fuse. If a fuse blows again after replace-
