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 internal heat build up and
adversely affect the life of the projector. Clean the air filters following the steps below.
Clean the air filters with a brush or rinse them softly. 3
When cleaning the air filters by rinsing, dry them well. Replace
the air filters properly. Make sure that the air filters are fully
inserted. 4
CAUTION
Do not operate the projector with the air filters removed.
Dust may accumulate on the LCD panel and the projection
mirror degrading picture quality.
Do not put small parts 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 environments
may cause poor image quality.
When using under dusty or smoky conditions, dust may accumulate on a lens, LCD panels, or optical elements inside the
projector. This condition may degrade the quality of a projected image.
When the above symptoms are noticed, contact your authorized dealer or service station for proper cleaning.
