Cleaning the Air Filters
The air filters prevent dust from accumulating on the surface of the optical elements inside the projector. Should the
air filters become clogged with dust particles, it will reduce cooling fans' effectiveness and may result in a buildup of
internal heat and adversely affect the life of the projector. Clean the air filters by following the steps below.
Cleaning the Air Filter 1 and 2
1 Press the latch and release it. Take off the filter covers.
Do not try to pull the delicate filter part.
2 Pull out the air filters.
When taking out the Air Filter 2, put your finger on the
air filters tab and pull.
3 Remove dust and dirt with a soft brush or a vacuum
cleaner. Be careful not to damage the air filters and do
not clean them with water.
When the Air Filter 1 gets dusty and dirty, replace it
with a new one. For ordering the replacement filter,
contact your sales dealer.
4
Put the air filters back into the position and close the
filter covers. Do not push the delicate filter part. Make
sure that the air filters are properly and fully inserted.
CAUTION
Do not operate the projector with the air filters
removed. Dust may accumulate on the LCD panel
degrading the picture quality of the projection mirror.
Do not put anything into the air intake vents. It may
result in malfunction of the projector.
RECOMMENDATION
We recommend avoiding dusty/smoky environments when
operating the projector. Usage in these environment may
cause a poor image quality.
When using the projector under dusty or smoky conditions, dust
may accumulate on a lens, LCD panels, or optical elements
inside the projector degrading the quality of a projected image.
When the symptoms above are noticed, contact your authorized
dealer or service station for proper cleaning.
