Cleaning the Air Filter and Vents

Clean the product's air filters or vents if they get dusty, or if you see a message telling you to clean them.
Note: Along with any message, you will also see an indicator like this. Projector 1 represents the commander and projector 2 represents the receiver. The green arrow points to the projector that the message is referring to.


  1. Turn off the product and unplug the power cords.
  2. Gently remove the dust using a small vacuum designed for computers or a very soft brush (such as a paintbrush).


    Note: You can remove an air filter so you can clean both sides of it. Do not rinse the air filter in water, or use any detergent or solvent to clean it.
    Caution:
    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.
  3. If dust is difficult to remove or an air filter is damaged, replace the air filter.
