Fuse Replacement

The fuse in the fuse holder in the power cable protects the equipment from high elec-
tric current and equipment fault. If you cannot turn on the power, check the fuse to see
if it has blown. Find the reason for the blown fuse before you replace the fuse. If the
fuse blows again after the replacement, contact your dealer for advice.
