Filter Instructions

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.
55), a Filter replacement icon (Fig.1) appears on the screen
and the WARNING FILTER indicator on the top panel lights
up (p.70). When you see this icon, replace the filter as soon
as possible (pp.29, 51). 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 1, the Last scroll
icon (Fig.3) appears on the screen, indicating that there is
one scroll left in the filter cartridge (p.55).
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.70). When you
see this icon, replace the filter cartridge (p.57) and reset the
Filter counter (p.58) and the Scroll counter (p.58).
When the filter is being scrolled using the remote control
unit (p.29) or the Filter control function in the setting
menu (p.51), 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.69).
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.70).

cause a breakdown.
