When and how should I clean or replace the air filter?

• 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.

  Replacing the Air Filter

  You need to replace the air filter in the following situations:
  • After cleaning the air filter, you see a message telling you to clean or replace it
  • The air filter is torn or damaged

  Note: Along with the 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.
  
  

  You can replace the air filter while the projector is mounted to the ceiling, if necessary. The illustrations here show the projector placed on a table.

  Note: The illustrations in this section show how to replace the commander projector's air filter, but you can replace the receiver projector's air filter using the same steps.

  1. Turn off the product and unplug the power cords.
  2. Place your finger into the groove at the top of the air filter cover and pull to open the cover.
     
  3. Pull the air filter out of the projector.
     
     

     Note: Air filters contain ABS resin and polyurethane foam. Dispose of used air filters according to local regulations.

  4. Place the new air filter in the projector as shown and push gently until it clicks into place.
     
  5. Close the air filter cover.
