Maintenance and Cleaning Cleaning the Air Filter The air filter prevents dust from accumulating on the surface of the optical elements inside the projector. Should the air filter become clogged with dust particles, it will reduce cooling fans' effectiveness and may result in a buildup of internal heat and adversely affects the life of the projector. Clean the air filter 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 filter by pulling the latches upward. 3 Clean up the dust on the projector and around the air vents. 4 Gently clean the filter by using a brush or blower. WARNING: Do not wash the filter with water and any other liquid matter. Otherwise the filter may be damaged. 5 Reinstall the filter into the projector properly. 6 Reset the filter counter in the Setting Menu. See "Resetting the Filter Counter" below. CAUTION Do not operate the projector with the air filter 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.
