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. 
56), a Filter replacement icon (Fig.1) appears on the screen 
and the WARNING FILTER indicator on the top panel lights 
up (p.74). When you see this icon, replace the filter as soon 
as possible (pp.30, 51).  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.56).
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.74). When you 
see this icon, replace the filter cartridge (p.58) and reset the 
Filter counter (p.59) and the Scroll counter (p.59).
When the filter is being scrolled by the remote control (p.30) 
or the Filter control function in the setting menu (p.51), 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.72).
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.74).

✔Note:
• Fig.1, Fig.2, Fig.3 or Fig. 4 will not appear when the Display 
function is set to “Off” (p.48), or during “Freeze” (p.29).
•
 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.
Fig  . 5    Filter replacement icon and 
“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.
● 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.
● 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.  
● 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  station  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.

–
   Did you provide appropriate space for the projector to be 
ventilated? Check the installing condition to see if the air 
vents of the projector are not blocked.
–
   Has the projector been installed near an Air-Conditioning/ 
Heating Duct or Vent? Move the installation of the 
projector away from the duct or vent.
–
   Is the filter clean? Replace the filter with a new one.
