16. MAINTENANCE, TROUBLESHOOTING
16.2 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.

it is approximately 25,000 hours. The actual life of the LCD is affected by the operating
environment (temperature, humidity, etc.). When nearing the end of its life-span, the
LCD brilliance does not adjust correctly. When this occurs, contact your local dealer
for advice.
