Maintenance and Care

Filter prevents dust from accumulating on the optical elements inside the projector. Should the filter becomes
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. This projector has an electrically operated filter which helps you
to replace the filter easily. The projector monitors the condition of the filter at all time and replaces a filter with
a new one automatically when it detects the clogging.
If the projector reaches a time set in the timer setting
(p.65), a Filter replacement icon (Fig.1) appears on the
screen and the WARNING FILTER indicator on the top
panel lights up (p.81). When you see this icon, replace
the filter as soon as possible (pp.30, 58). If the filter is out
of scroll and the projector reaches a time set in the timer
setting, Fig. 2 appears on the screen, indicating that the
filter cartridge replacement is necessary.
When the filter scroll is counted down to 0, the Last scroll
icon (Fig.3) appears on the screen, indicating that there is
one scroll left in the filter cartridge (p.65).
If the projector detects that the filter is clogged and
no scroll is left in the filter cartridge, a Filter cartridge
replacement icon (Fig. 4) appears on the screen and the
WARNING FILTER indicator on the top panel lights up
(p.81). When you see this icon, replace the filter cartridge
(p.67) and reset the Filter counter (p.68) and the Scroll
counter (p.68).
When the filter is being scrolled using the remote control
(p.30) or the Filter control function in the setting menu
(p.58), a Filter replacement icon and Please wait...
message (Fig.5) appear on the screen and the WARNING
FILTER indicator blinks slow (approx. 2 seconds ON, 2
seconds OFF) (p.79).
The WARNING FILTER indicator blinks fast when the
projector detects an abnormal condition, the filter cartridge
is not installed properly, or the filter scroll is not working
properly (p.81).
