Air filter units

Filter prevents dust from accumulating on the optical elements inside the projector. Should the filter become
clogged with dust particles, it will reduce cooling fans' effectiveness and may result in internal heat buildup
and adversely affect the life of the projector.
If the air filter units become clogged, it will result in internal heat buildup, the power of the projector may
be turned off for safety.
If a “Filter warning” icon appears on the screen, replace the filters immediately.
