Maintenance and cleaning

Cleaning the filter

The air filter prevents dust from accumulating on the surface of the optical elements inside
the projector. Should the air filter become clogged with dust particles, it will reduce cooling
fans' effectiveness and may result in a buildup of internal heat and adversely affects the life of
the projector. If the Filter warning icon appears on the screen, the air filter should be cleaned
immediately. Clean the air filter following the steps below.
1 Turn off the projector, and unplug the AC
power cord from the AC outlet.
2 Remove the air filter.
3 Gently clean the filter with a brush.
4 Reinstall the filter into the projector properly.
Caution
Do not operate the projector with
the air filter removed. Dust may
accumulate on the optical elements,
degrading picture quality.
Do not put any small objects into the
air intake vents. Otherwise, it may
result in malfunction of the projector.

projector. When the symptoms above are
