Note
• The projector consumes about 6W of power in standby. We recommend you to unplug
the AC power cord if you will not use the projector for an extended period.
PRECAUTIONS
• Before unplugging the AC power cord, make sure that the LAMP indicator is off.
Unplugging the AC power cord and cutting off the power while the projector is running or
being cooled will shorten the life of the lamp. However, please unplug the AC power
cord if the projector locks up or acts abnormally.
• If the AC power cord was unplugged before cooling was complete, give the lamp
sufficient time to cool before plugging it back in. If the lamp overheats, it may fail to light,
and its lifetime will be shortened.
LCD Panels
LCD panels wear out. In order to prolong the lifetime of your LCD panel, take the
following precautions.
• In order to extend the lifetime of the LCD panel, always turn off the power when not in
use, and make sure that the lamp is off. Keeping the lamp off is also very effective at
saving electricity.
• If the air filter becomes dirty and clogged, the projector's internal temperature will rise,
shortening the lifetime of the LCD panel and causing malfunctions. Clean the air filter
from time to time p.32 , and replace it periodically. Contact the store where you
purchased your projector, or your local Service Station for replacement air filters.
