Turn off the projector, and unplug the AC power cord 

from the AC outlet.

First, clean up the dust on the projector and around the 

air vents.

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.

Pull out the filter cover from the projector and then 

remove the filter.

Reinstall the filter into the projector properly.

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.

Gently clean the filter by using a brush or blower.

Reset the filter counter in the Setting Menu. See 

“Resetting the Filter Counter” below.

Press and hold the 
filter cover and pull
