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. 
59), a Filter replacement icon (Fig.1) appears on the screen 
and the WARNING FILTER indicator on the top panel lights 
up (p.75). When you see this icon, replace the filter as 
soon as possible (p53).  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.59).
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.75). When you 
see this icon, replace the filter cartridge (p.61) and reset the 
Filter counter (p.62) and the Scroll counter (p.62).
When the filter is being scrolled by the Filter control function 
in the setting menu (p.53), 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.73).
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.75).

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 life may differ from lamp to lamp and according to the environment of use. There is no guarantee of  the  same  life  for  each  lamp.  Some  lamps  may  fail  or  terminate  their  life  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 lights 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  A  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.
