filters become clogged with dust particles, it will reduce cooling fans’ effectiveness and may result in a buildup of internal
heat and adversely affect the life of the projector. Clean the air filters by following the steps below.
CAUtIoN
Do not operate the projector with the air filters removed. Dust
may accumulate on the LCD panel degrading the picture
quality of the projection mirror. Do not put anything into the air
intake vents. It may result in malfunction of the projector.
