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.
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 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.
When cleaning the air filters by rinsing, dry them
well. Replace the air filters properly. Make sure
that the air filters are fully inserted.
CAUTION
Do not operate the projector with the air filters
removed. Dust may accumulate on the optical
elements degrading picture quality.
Do not put small parts into the air intake vents. It
may result in malfunction of the projector.
