Maintenance and CleaningCleaning the Filter

Filters prevent dust from accumulating on the optical elements inside the projector. Should the filters become 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 appears on the screen, clean the filters immediately. Clean the filters by following the steps below.

1

Turn off the projector, and unplug the AC power cord

 

from the AC outlet.

2

Turn the projector over and remove the filters by

 

pulling the latches upward.

3

Gently clean the filters by using a brush or rinse them

 

softly.

4

When rinsing the filters, dry them well. Replace the

filters properly. Make sure that the filters are fully inserted to the projector.

CAUTION

Do not operate the projector with the filters 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.

RECOMMENDATION

We recommend avoiding dusty/smoky environments when you operate the projector. Usage in these environments may cause poor image quality.

When using the projector under dusty or smoky conditions, dust may accumulate on a lens, LCD panels, or optical elements inside the projector degrading the quality of a projected image. When the symptoms above are noticed, contact your authorized dealer or service station for proper cleaning.
