MaintenanceandCleaning
Filter prevents dust from accumulating on the optical elements inside the projector. Should the Filter 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, replace the Filter immediately.
Replace the filter by following the steps 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.
- Do not wash the filter with water or any other
liquid Matter. Otherwise the filter may be
damaged.
