2.5 Air Filter Care and Cleaning

The removable air filter prevents dust from accumulation on the surface of the
projection lens and projection mirror. Should the air filters become clogged with dust
particles, it will reduce the cooling fan's effectiveness and may result in internal heat
build up and adversely affect the life of the projector.
To clean up the air filters, follow the cleaning procedure below:
1. Turn the projector off, and
disconnect the AC power cord from
the AC outlet.
2. Turn the projector upside down and
remove the air filters by pulling the
latches upward.
3. Clean the air filters with a brush or
wash out dust and particles.
4. Replace each air filter properly.
Make sure that the air filters are
fully inserted.
CAUTION
[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 optical
elements inside the projector. The condition may degrade the quality of a projected
image.
When the above symptoms are noticed, please clean up the LCD panel and lens
following to the "Cleaning Method".
Do not operate the projector with the air filters removed. Dust may
accumulate on the LCD panel and the mirror, and it may spoil the fine
picture image.
Do not put the small parts into the air intake vents. It may result in the
malfunction of the projector. The air filter is small parts. Take care that
children don't eat or swallow it.
