Cleaning the Projector and the Air Filter
Cleaning the Air Filter
The air filter protects the lens and mirror inside the projector from
dust and dirt. Should the air filter become clogged with dust, the
projector may be damaged since it will block the air flow into the
projector and raise the internal temperature of the projector.
The following screen is displayed when turning on the projector if the air filter needs
to be cleaned. Clean the air filter if it is displayed.
Follow the procedure below when cleaning the air filter.
1
Turn the power of the projector
off and pull out the power plug.
2
As you press the top and bottom
of the air filter cover to release
the lock, remove the cover.
3
Open the filter cover and remove
it.
• Only the [ ], [ ], OK and POWER buttons are
available while this screen is displayed. (When you
press the POWER button, the "Push POWER button
again to turn off power." message appears.)
• When this screen has disappeared after being
displayed for 10 seconds, all buttons become operable.
