Maintenance and Cleaning Cleaning the Air Filters Air filters prevent dust from accumulating on the surface of the optical elements inside the projector. Should the air filters become clogged with dust particles, they 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. 1 Turn off the projector, and unplug the AC power cord from the AC outlet. 2 Turn over the projector and remove the air filters by pulling the latches upward. 3 Clean the air filters with a brush or rinse them softly. When rinsing the air filters, dry them well. 4 Replace the air filters properly. Make sure that the air filters are fully inserted. CAUTION Do not operate the projector with the air filters removed. Dust may accumulate on the optical elements degrading picture quality. Do not put anything into the air intake vents. Otherwise it 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 you use the projector under dusty or smoky conditions, dust may accumulate on the 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.
