Cleaning the dust filtersThe dust filters catch dust and other particles in the air. If the filters become 
clogged, the projector does not cool properly and may malfunction. In dirty 
or dusty environments, they should be cleaned after every 100 hours of use. 
Failure to do so may result in premature lamp failure. 
There are two filters, one mesh filter attached to the dust filter door and one 
metal grid filter adjacent to the lamp door. 1
