Filter prevents dust from accumulating on the optical elements inside th\
e projector. Should the filter become
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. If a “Filter warning” icon appears on the screen, replace the fi\
lters
immediately. Replace the filters by following the steps below.
Put new filters back into the position. Make sure that 
the filters are fully inserted to the projector.3
CAUTION
– Do not operate the projector with the filters 
  removed. Dust may accumulate on the optical 
  elements degrading picture quality.
– Do not put anything into the air vents. Doing so
  may result in malfunction of the projector.
–Do not wash the filters with water or any other 
  liquid matter. Otherwise the filters may be
  damaged.

Thread the string through the hole on the lens cap and 
then tie a knot in the string to secure it in place.
To pass the other end of the string into the hole on the 
top of the projector and pull at it.
Maintenance and Cleaning
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.
CAUTION

Maintenance and Cleaning
When  the  projection  lamp  of  the  projector  reaches  its  end 
of  life,  the  Lamp  replacement  icon  appears  on  the  screen 
and  LAMP  REPLACE  indicator  lights  yellow.  Replace  the 
lamp  with  a  new  one  promptly.  The  timing  when  the  LAMP 
REPLACE  indicator  should  light  is  depending  on  the  lamp 
mode.
Follow these steps to replace the lamp.
For  continued  safety,  replace  with  a  lamp  of  the 
same  type.  Do  not  drop  a  lamp  or  touch  a  glass 
bulb! The glass can shatter and may cause injury.
Allow  a  projector  to  cool  for  at  least  45  minutes 
before  you  open  the  Lamp  Cover. The  inside  of 
the projector can become very hot.
CAUTION
Unplug the AC power cord. Let the projector cool for at 
least 45 minutes.
Loosen the three (3) screws that secure the lamp. Lift 
the lamp out of the projector by using the handle.

CAUTION
When  replacing  the  lamp  because  it  has  stopped  illuminating,  there  is  a  possibility  that  the  lamp  may  be 
broken.
If replacing the lamp of a projector which has been installed on the ceiling, you should always assume that 
the  lamp  is  broken,  and  you  should  stand  to  the  side  of  the  lamp  cover,  not  underneath  it.  Remove  the 
lamp cover gently. Small pieces of glass may fall out when the lamp cover is opened. If pieces of glass get 
into your eyes or mouth, seek medical advice immediately.
 Note:
•	When	Mode	2	is	selected	in	the	Lamp	life	control	menu,	if	the	projection	lamp	of	the	projector	reaches	its	
  end of life, the lamp replacement icon appears on the screen, and  the\
 projector is turned off automatically 
  after 3 minutes.
  •	The Lamp replacement icon will not appear when the Display function is s\
et to Off (p.48), during Freeze 
(p.25), or No show (p.26).

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 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.
●  If  the  projector  indicates  that  the  lamp  should  be  replaced,  i.e.,  if  the  LAMP  REPLACE  indicator  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 REPLACE indicator lighted may increase the risk of lamp explosion.  
●  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 SAFETy  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.  
          LAMP HANDLING PRECAUTIONS
