Fuse Replacement

A fuse is in the fuse holder on the power cable and inside the power supply unit, and they protect
the equipment from reverse polarity of the ship's mains and equipment fault. If a fuse blows, find
out the cause before replacing it. Use the correct fuse. Using the wrong fuse will damage the
equipment and void the warranty.
