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.
