Caution: Do not use excessive force when tapping the air filter, or it may crack and become
unusable. Do not rinse the air filter in water, or use any detergent or solvent to clean it. Do not use
canned air; the gases may leave a residue, or push dust and debris into the projector's optics or
other sensitive areas.
5. Vacuum the front of the air filter (the side with the tabs) to remove any remaining dust.
Note: If dust is difficult to remove or the air filter is damaged, replace the air filter.
