FILTER CARE/REPLACEMENT PROCEDURE
The filter prevents dust from accumulating on the optical elements inside the projector. Should the
filter become clogged with dust particles, the effectiveness of the cooling fans will be reduced and may
result in internal heat buildup which will adversely affect the life of the projector. If the projector
reaches a time set in the timer setting, a Filter replacement icon
appears on the screen and the
WARNING FILTER indicator on the top panel lights up (refer to Figure 1). When you see this icon,
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,
appears on the screen indicating filter cartridge replacement is necessary.
When the filter scroll is counted down to 1, the Last scroll icon
appears on the screen, indicating
there is one scroll left in the filter cartridge.
If the projector detects that the filter is clogged and no scroll is left in the filter cartridge, a Filter
cartridge replacement icon
appears on the screen and the WARNING FILTER indicator on the top
panel lights up (refer to Figure 1). When you see this icon, replace the filter cartridge and reset the
Filter counter and the Scroll counter.
When the filter is being scrolled by the remote control or the Filter control function in the setting
menu, a Filter replacement icon and “Please wait...” message
appear on the screen and the
WARNING FILTER indicator blinks slow (approx. 2 seconds ON, 2 seconds OFF).
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.
NOTICES
• The icons will not appear when the Display function is set to “Off”, or during “Freeze” .
• The filter cannot be rewound; it can be scrolled 9 times since the filter cartridge has 10 scrolls.
• The filter cartridge is disposable. Do not clean and reuse the filter cartridge; Do not expose the
filter cartridge to water or liquid, or it may cause a malfunction.
• Replace the filter cartridge after all the scroll is used up. If you replace the filter cartridge when
there are scrolls remaining in the filter cartridge, the filter counter and the scroll counter do not
recognize the correct number of remaining scrolls and the reset function cannot work properly. It
may cause a malfunction.
• The used part of the filter can be seen on the edge of the Filter cartridge after scrolling the filter,
but there is no problem for the use of the projector.
• Do not use the filter cartridge with other projectors. The filter counter and the scroll counter do
not recognize the correct number of remaining scrolls of the used filter cartridge and the reset
function cannot work properly. It may cause a malfunction.
• Make sure that the projection lamps are turned off when you are replacing the filter cartridge. If
you replace the filter cartridge when the projection lamps are turned on, the projector will be shut
down automatically for safety purposes.
• Do not forget to reset the filter counter and the scroll counter after replacing the filter cartridge.
If you do not reset the filter counter and the scroll counter, the projector cannot recognize the
correct number of remaining scrolls and it may cause a malfunction.
• When the projector is in use for 3 minutes without a new filter cartridge replacement following
display “Filter Cartridge Replament” icon, the projector is turned off automatically to prevent
damage to the optical components.
