Maintenance and Filter Cleaning

Cleaning the Filter

Filter prevents dust from accumulating on the optical elements inside the projector. Should the filter becomes
clogged with dust particles, it will reduce cooling fans' effectiveness and may result in internal heat buildup and
adversely affect the life of the projector. If a "Filter warning" icon (yellow or red) appears on the screen and the
WARNING FILTER indicator lights or blinks, clean the filter immediately. Clean the filter by following the steps
below.
1 Turn off the projector, and unplug the AC power cord
from the AC outlet.
2 First, clean up the dust on the projector and around the
air vents.
3 Pull out the filter cover from the projector and then
remove the filter.
4 Gently clean the filter by using a brush or blower.
WARNING: Do not wash the filter with water and
any other liquid matter. Otherwise the filter may
be damaged.
5 Reinstall the filter into the projector properly.
6 Reset the filter counter in the Setting Menu. See
"Resetting the Filter Counter" below.
CAUTION
Do not operate the projector with the filter
removed. Dust may accumulate on the optical
elements degrading picture quality.
Do not put anything into the air vents. Doing so
may result in malfunction of the projector.
