Cleaning and replacing the air filter

If the air filter becomes clogged with dust, the internal temperature of the
projector will rise, the TEMP indicator will flash and the projector power will
turn off. The air filter should be cleaned every 100 hours of use,
depending on the location where the projector is being used.
