Maintenance and Care
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 replac\
es a filter with a 
new one automatically when it detects the clogging. 
If the projector reaches a time set in the timer setting (p. 
67), a Filter replacement icon (Fig.1) appears on the screen 
and the WARNING FILTER indicator on the top panel lights 
up (p.87). When you see this icon, replace the filter as soon 
as possible (pp.30, 61). 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.67).
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.87). When you 
see this icon, replace the filter cartridge (p.72) and reset the 
Filter counter (p.73) and the Scroll counter (p.73).
When the filter is being scrolled by the remote control (p.30) 
or the Filter control function in the setting menu (p.61), 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.85).
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.87).

✔Note:
• 
Fig.1, Fig.2, Fig.3 or Fig. 4 will not appear when the Display function is set to “Off” (p.53), or during “Freeze” (p.30).
•  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 problem for the use of the projector.

“Please wait...” message. 
• 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 purposes.
•  Do not forget to reset the filter counter and the scroll counter in 
the setting menu after replacing the filter cartridge. If you forget to reset the filter counter and the scroll counter, 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 getting 
the filter cartridge replaced after the Fig.4 appears on the screen, the projector is turned off automatically to prevent the damage of optical components.

This projector uses a high-pressure lamp which must be handled carefully and properly. 
Improper handling may result in accidents, injury, or create a fire hazard.
l Lamp  lifetime  may  differ  from  lamp  to  lamp  and  according  to  the  environment  of  use. There  is  no 
guarantee  of  the  same  lifetime  for  each  lamp.  Some  lamps  may  fail  or  terminate  their  lifetime  in  a 
shorter period of time than other similar lamps.
l If  the  projector  indicates  that  the  lamp  should  be  replaced,  i.e.,  if  the  LAMP  1/2  REPLACE  indicators 
light up, replace the lamp with a new one IMMEDIATELY after the projector has cooled down. (Follow 
carefully the instructions in the Lamp Replacement section of this manual.) Continuous use of the lamp 
with the LAMP 1/2 REPLACE indicators lighted may increase the risk of lamp explosion.
l Lamp  may  explode  as  a  result  of  vibration,  shock  or  degradation  as  a  result  of  hours  of  use  as  its 
lifetime  draws  to  an  end.  Risk  of  explosion  may  differ  according  to  the  environment  or  conditions  in 
which the projector and lamp are being used.
IF A LAMP EXPLODES, THE FOLLOWING SAFET y PRECAUTIONS SHOULD BE TAKEN.
If  a  lamp  explodes,  disconnect  the  projector’s  AC  plug  from  the  AC  outlet  immediately.  Contact  an 
authorized  service  center  for  a  checkup  of  the  unit  and  replacement  of  the  lamp.  Additionally,  check 
carefully to ensure that there are no broken shards or pieces of glass around the projector or coming out 
from  the  cooling  air  circulation  holes.  Any  broken  shards  found  should  be  cleaned  up  carefully.  No  one 
should  check  the  inside  of  the  projector  except  those  who  are  authorized  trained  technicians  and  who 
are familiar with projector service. Inappropriate attempts to service the unit by anyone, especially those 
who are not appropriately trained to do so, may result in an accident or injury caused by pieces of broken 
glass.

cleaners, solvents, or other harsh chemicals might scratch 
the surface of the lens.
Cleaning the Projector Cabinet
Turn off the projector, press the Main On/Off Switch to Off 
and unplug the AC power cord from the AC outlet before 
cleaning.
Gently wipe the projector body with a soft dry cleaning 
cloth. When the cabinet is heavily soiled, use a small amount 
of mild detergent and finish with a soft dry cleaning cloth. 
Avoid using an excessive amount of cleaner. Abrasive 
cleaners, solvents, or other harsh chemicals might scratch 
the surface of the cabinet.
When the projector is not in use, put the projector in an 
appropriate carrying case or cover to protect it from dust and 
scratches.
Cleaning the Projection Lens
CAUTION
Do not use any flammable solvents or air sprays 
on the projector and in its vicinity. The explosion or 
fire hazard may occur even after the AC power cord 
is unplugged because the temperature inside the 
projector is extremely high due to the lamps. 
In addition, there is a risk that the internal parts 
may be damaged not only by the flammable air 
spray but also by the cold air.
