14.2 Replacement of Fuse, Battery
The fuse on the power cable of the display unit protects the system from reverse polarity of the
ship's mains and equipment fault. If the fuse blows, find the cause before replacing the fuse.
Use only a 3A fuse. Using the wrong fuse will damage the unit and void the warranty.
Do not open the equipment.
Hazardous voltage which can
cause electrical shock, burn or
serious injury exists inside the
equipment. Only qualified
personnel should work inside
the equipment.
