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 filters immediately. Replace the filters by following the steps below.
Put new filters back into the position. Make 
sure that the filters are fully inserted to the 
projector.
