							CheckRemedy
Are the image signals being output to the projector?
(Only when projecting images from a laptop computer or a
computer with a built-in LCD screen)If the image signals are only being output to the computer's LCD monitor or to the accessory monitor, you need to
change the output to an external destination as well as the computer's own monitor. For some computer models, when
the image signals are output externally, they no longer appear on the LCD monitor or accessory monitor.
If the connection is made while the power of the projector or computer is already turned on, the Fn key (Function key)
that changes the computer's image signal to external output may not work. Turn the power for the computer and the
projector off and then back on again.

Has condensation formed on the lens? If the projector is suddenly taken from a cold environment to a warm environment, or if sudden ambient temperature
changes occur, condensation may form on the surface of the lens, and this may cause the images to appear fuzzy. Set the
projector up in the room about one hour before it is used. If condensation forms on the lens, turn the projector off and
wait for the condensation to disappear.

							Maintenance
This  chapter  provides  information  on  maintenance  procedures  to  ensure  the  best  level  of  performance  from  the  projector  for  a  long  time  to  come. 
						

							You  should  clean  the  projector  if  it  becomes  dirty  or  if  the  quality  of
projected  images  starts  to  deteriorate.AttentionTurn  off  the  projector's  power  before  cleaning.
Cleaning  the  Projector's  Surface
Clean  the  projector's  surface  by  wiping  it  gently  with  a  soft  cloth.
If  the  projector  is  particularly  dirty, moisten  the  cloth  with  water  containing
a  small  amount  of  neutral  detergent,  and  then  firmly  wring  the  cloth  dry
before  using  it  to  wipe  the  projector's  surface.AttentionDo  not  use  volatile  substances  such  as  wax,  alcohol,  or  thinner  to  clean  the
projector's  surface.  The  quality  of  the  case  may  change  or  become  discolored.
Cleaning  the  Lens
Use  a  commercially  available  cloth  for  cleaning  glasses  to  gently  wipe  the
lens.
 Warning
Do  not  use  sprays  that  contain  flammable  gas  to  remove  dust  and  lint  from  the
lens.  The  projector  may  catch  fire  due  to the  high  internal  temperature  of  the
lamp.
AttentionDo  not  rub  the  lens  with  harsh  materials  or  subject  the  lens  to  shocks,  as  it
can  easily  become  damaged.
Cleaning  the  Air  Filter
Clean  the  air  filter  and  the  air  intake vent  when  the  following  message  is
displayed.
"The  projector  is  overheating.  Make  sure  nothing  is  blocking  the  air  vent,
and  clean  or  replace  the  air  filter."Attention•If  dust  collects  on  the  air  filter,  it  can  cause  the  internal  temperature  of  the
projector  to  rise,  and  this  can  lead  to  problems  with  operation  and  shorten
the  optical  engine's  service  life.  Clean  the  air  filter  immediately  when  the
message  is  displayed.
•Do  not  rinse  the  air  filter  in  water.  Do  not  use  detergents  or  solvents.
