Air filter care and cleaning
Air filters prevent dust from accumulating on 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 ad-
versely affect the life of the projector. Clean the air filters following the steps below.
Air filters
Pull up and remove.
RECoMMENdAtIoN:
We recommend avoiding dusty/smoky environments
when operating the projector. Usage in these
environments may cause 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. This condition may degrade the quality of a projected image.
When the symptoms above are noticed, contact your authorized dealer or service station for proper cleaning.
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.
1. Turn off the projector, and disconnect the AC power cord
from the AC outlet.
. Turn over the projector and remove the air filters by pulling
the latches upward.
3. Clean the air filters with a brush or rinse them softly.
