Cleaning the filter
The air filter prevents dust from accumulating on the surface of the optical elements inside the projector. Should the air
filter become clogged with dust particles, it will reduce cooling fans' effectiveness and may result in a buildup of internal
heat and adversely affects the life of the projector. If the Filter warning icon appears on the screen, the air filter should be
cleaned immediately. Clean the air filter following the steps below.
