The Shutter Management function turns off the projection 
lamp when the projector is left with the shutter closed 
and the set time has passed away. The count-down time 
can be set between 5 and 480 minutes. When the count-
down time has elapsed, the shutter will be opened up 
automatically and the lamp will be turned off to cool itself 
down. The SHUTTER indicator is blinking blue during 
this cooling-off period. When the lamp has been fully 
cooled down, the POWER indicator turns green lighting 
and the SHUTTER indicator keeps blinking. Should the 
ON / STAND-BY button be pressed in this condition, 
the projection lamp will be turned on and the SHUTTER 
indicator turns off.

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).Fig.1Filter replacement icon

RECOMMENDATION
We recommend avoiding dusty/smoky environments 
when operating the projector. Usage in these 
environments may cause a poor image quality.
When using the projector under dusty or smoky 
conditions, dust may accumulate on a lens, liquid crystal 
panels, or optical elements inside the projector. Such 
condition may degrade the quality of the projected image.
When the symptoms above are noticed, contact your 
authorized dealer or service center for proper cleaning.
