When and how should I clean the air vents?

• Clean the projector's air vents if they get dusty, or if you see a message telling you to clean them.
  1. Turn off the projector and unplug the power cord.
  2. Carefully remove the dust using a vacuum cleaner or a brush.
     
     

     Caution:
     Do not use canned air. The gases may leave a flammable residue or push dust and debris into the projector's optics or other sensitive areas.
