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. 56), a Filter
replacement icon (Fig.1) appears on the screen and the WARNING
FILTER indicator on the top panel lights up. 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, Fig. appears
on the screen, indicating that the filter cartridge replacement is nec-
essary.
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.
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) ap-
pears on the screen and the WARNING FILTER indicator on the top
panel lights up. 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 Fil-
ter control function in the setting menu, a Filter replacement icon
and “Please wait...” message (Fig.5) appear on the screen and the
WARNING FILTER indicator blinks slow (approx. seconds ON,
seconds OFF).
The WARNING FILTER indicator blinks fast when the projector de-
tects an abnormal condition, the filter cartridge is not installed prop-
erly, or the filter scroll is not working properly.

Note:
• Fig.1, Fig., Fig.3 or Fig. 4 will not appear when the
Display function is set to “Off”, or during “Freeze”.
• The filter cannot be rewound.
• The filter 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 breakdown.
• Replace the filter cartridge after all the scroll is used up. If
you replace the filter cartridge when there are some scrolls
left 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 breakdown.
• The used part of the filter can be seen on the edge of the
Filter cartridge after scrolling the filter, but there is no prob-
lem for the use of the projector.
• Do not use the filter cartridge with other projector. 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
breakdown.
• 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 pur-
poses.
• Do not forget to reset the filter counter and the scroll coun-
ter in the setting menu after replacing the filter cartridge.
If you forget to reset the filter counter and the scroll coun-
ter, the projector cannot recognize the correct number of
remaining scrolls and it may cause a breakdown.
• When the projector is kept used for 3 minutes without get-
ting the filter cartridge replaced after the Fig.4 appears on
the screen, the projector is turned off automatically to pre-
vent the damage of optical components.
