Cleaning 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. Turn the projector upside down.
3. 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.
