Maintenance and cleaning
Cleaning the air 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 Press the air filters lightly, the air filters will
pop pout automatically, Remove the air
filters.
3 Gently clean the air filters with a brush.
4 Reinstall the air filters into the projector
properly. Please ensure that the air filters
are intalled completely into the projector.
Caution
Do not operate the projector with
the air filter removed. Dust may
accumulate on the optical elements,
degrading image quality.
Do not put any small objects into the
air intake vents. Otherwise, it may
result in malfunction of the projector.
Recommendation
We recommend avoiding dusty/smoky
environments when you operate the projector.
Usage in these environments may cause poor
image quality.
When you use the projector under dusty or
smoky conditions, dust may accumulate on the
lens or optical elements inside the projector.
When the symptoms above are noticed, contact
your authorized dealer or service station for
proper cleaning.
