Cleaning and Replacing the Filters
The projector has several filters that should be cleaned periodically to 
remove trapped dust. If the filters become clogged, the projector can 
overheat and damage can result. Clean the filters approximately every 
three months, or after every 100 hours of use; clean them more often 
if you use the projector in a dusty environment.

■The projected image gets darker or starts to deteriorate.
■The message LAMP REPLACE appears on the screen and the 
lamp warning light   flashes orange.
