Maintenance and cleaning
Cleaning the filter
Filter counter reset
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.
Be sure to reset the filter counter after cleaning
or replacing the filter.
1. Press Menu on the remote control to display
the screen menu. Press
to select
"Expand", then press the OK button.
2. Press
to select "Filter counter", and then
press the OK button.
Press
to select "Filter counter reset" and
press the OK button, "Filter counter
Reset?" appears on screen, select "Yes" to
continue.
3. When another dialog box pops up, select
"Yes" to reset the filter.
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.
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, LCD panels, or optical elements inside the
projector. When the symptoms above are
noticed, contact the authorized dealer or
service station for proper cleaning.
