12.2 Replacement of Fuse,
Battery
The fuse on the power cable protects the
system from reverse polarity of the ship’s
mains and equipment fault. If the fuse blows,
find the cause before replacing it. Use only a
3A fuse. Using the wrong fuse will damage
the unit and void the warranty.
Use the correct fuse.
Use of a wrong fuse can cause fire or
equipment damage.
