Maintenance and Cleaning
Filter prevents dust from accumulating on the optical elements inside the projector. Should the filters 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, clean the filters 
immediately. Clean the filters by following the steps below.
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.
RECOMMENDATION
 We recommend avoiding dusty/smoky environments 
when you operate the projector  . Usage in these 
environments may cause poor image quality  .
  When using the projector under dusty or smoky conditions, 
dust may accumulate on a lens, LCD panels, or optical 
elements inside the projector degrading the quality of a 
projected image. When the symptoms above are noticed, 
contact your authorized dealer or service station for proper 
cleaning.
Be sure to reset the Filter counter after cleaning or replacing 
the filters.

mode.
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

Maintenance and Cleaning
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  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.  
          LAMP HANDLING PRECAUTIONS
