If the Filter counter reached a time set in the timer
setting, a Filter replacement icon (Fig.2) appears on
the screen and the WARNING FILTER indicator on
the top panel lights up. Replace the filter as soon as
possible. If the filter is out of scroll and the projector
reaches a time set in the timer setting, Fig. 3 appears
on the screen and the WARNING FILTER indicator
lights up. Replace the filter cartridge as soon as pos-
sible.
If 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 lights up. Replace the filter cartridge as
soon as possible.
Note:
•
Fig.2, Fig.3 and Fig.4 icon will not appear when the
Display function is set to “Off”, or during “Freeze”.
