  Cleaning the Air Filter

  2. Lift the tab on the bottom of the air filter cover and pull down to remove the cover.
     
  3. Pull the air filter out of the projector.
     
  4. Tap each side of the air filter 4 to 5 times to shake off any excess dust.
     
     

     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.
