Replacing the Fuse

The fuse at the rear of the processor unit
in the display unit protects the equipment
from overcurrent (overvoltage in case of
AC set) and equipment fault. If you cannot
turn on the power, first check the fuse.
Find the cause of the trouble before
replacing the fuse. Be sure to use the
proper fuse. Use of a wrong fuse can
seriously damage the equipment and void
the warranty.
