Replacing the unit
Air filter unit
The air filter prevents dust from accumulating on 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 internal heat
buildup and adversely affect the life of the projector.
Also, if the internal temperature of the unit becomes high, the power of the projector may be turned off to protect
internal components.
If a warning message appears on the screen, replace the air filter immediately.
Consult your dealer to purchase a replacement air filter unit (ET-RFV300).
