Replacing the unit
Air filter unit
 
J
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 a “Filter warning” icon appears on the screen, replace the air filter unit immediately. Replace it with the 
separately sold ET-RFT100 replacement filter unit. Consult your supplier when you purchase a replacement filter.
