Maintenance and Care Air Filter Care 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, clean the filter immediately. Clean the filter by following the steps below. 1 Turn off the projector, and unplug the AC power cord from the AC outlet. 2 Pull out the air filter from the projector. 3 Clean the filter with brush out dust and particles. 4 Replace the air filter in a projector. AIR FILTER CAUTION Do not operate the projector with the Air Filter(s) removed. Dust may accumulate on the LCD Panels and Projection Mirrors degrading the picture quality. Do not put anything into the air intake vents. Doing so may result in a malfunction of the projector. Failure to properly clean the projector's air filters (in accordance with the instructions in your Projector's Operating Manual, or more frequently in any environment which is somewhat dusty or smoky) could result in overheating and will void the warranty on the projector.
