Maintenance and Cleaning

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.
