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

							The  projector  supports  the  following  four  different  projection  methods.
Install  according  to  the  conditions of  the  installation  location.
 Warning
•A  special  method  of  installation  is  required  when  suspending  the  projector
from  a  ceiling  (ceiling  mount).  If  it  is  not  installed  correctly,  it  could  fall
causing  an  accident  and  injury.•If  you  use  adhesives  on  the  Ceiling  mount  fixing  points  to  prevent  the
screws  from  loosening,  or  if  you  use  things  such  as  lubricants  or  oils  on
the  projector,  the  projector  case  may  crack  causing  it  to  fall  from  its
ceiling  mount.  This  could  cause  serious  injury  to  anyone  under  the  ceiling
mount  and  could  damage  the  projector.
When  installing  or  adjusting  the  Ceiling  mount,  do  not  use  adhesives  to
prevent  the  screws  from  loosening  and  do  not  use  oils  or  lubricants  and  so
on.AttentionDo  not  use  the  projector  on  its  side.  This  may  cause  malfunctions  to  occur.
•Project images from in front of
the screen. (Front projection)
•Project images from behind a 
translucent screen. (Rear

							You  should  clean  the  projector  if  it  becomes  dirty  or  if  the  quality  of
projected  images  starts  to  deteriorate.
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  classes  to  gently  wipe
the  lens.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.q
•If  a  message  is  frequently  displayed,  even  after  cleaning,  it  is
time  to  replace  the  air  filter.  Replace  it  with  a  new  air  filter.
s p.72
•It  is  recommended  that  you  clean  these  parts  at  least  once  every
three  months.  Clean  them  more  often  than  this  if  using  the
projector  in  a  particularly  dusty  environment.

							This  section  explains  how  to  replace  the  Remote  Control  batteries,  the
Lamp,  and  the  air  filter.
Replacing  the  Remote  Control  Batteries
If delays in the responsiveness of the Remote Control occur or if it
does  not  operate  after  it  has  been  used  for  some  time,  it  probably
means  that  the  batteries  are  becoming  flat.  When  this  happens,  replace
them  with  new  batteries.  Have  two  AA  size  manganese  or  alkaline
batteries  ready.  You  cannot  use  other  batteries  except  for  the  AA  size
manganese  or  alkaline.AttentionMake  sure  you  read  the  Safety  Instructions  before  handling  the  batteries.  
s 
Safety  InstructionsProcedureA
Remove  the  battery  cover.
While  pushing  the  battery  compartment  cover  catch,  lift  the  cover
up.
B
Replace  the  old  batteries  with  new  batteries. Caution
Check  the  positions  of  the  (+)  and  (-)  marks  inside  the  battery  holder  to
ensure  the  batteries  are  inserted  the  correct  way.C
Replace  the  battery  cover.
Press  the  battery  compartment  cover  until  it  clicks  into  place.

							Replacing  the  LampLamp  replacement  period
It  is  time  to  replace  the  Lamp  when:
•The  message  "Replace  the  lamp.  "  is  displayed  when  you  start
projecting.A  message  is  displayed.
•The  Lamp  indicator  flashes  orange.•The  projected  image  gets  darker  or  starts  to  deteriorate.
Attention•The  lamp  replacement  message  is  set  to  appear  after  the  following  time
periods  in  order  to  maintain  the  initial  brightness  and  quality  of  the
projected  images.  
s
 p.37
When  used  continually  at  High  Brightness:  About  5000  hours
When  used  continually  at  Low  Brightness:  About  6000  hours
•If  you  continue  to  use  the  Lamp  after  the  replacement  period  has  passed,
the  possibility  that  the  lamp  may  explode  increases.  When  the  Lamp
replacement  message  appears,  replace  the  Lamp  with  a  new  one  as  soon  as
possible,  even  if  it  is  still  working.•Depending  on  the  characteristics  of  the  Lamp  and  the  way  it  has  been
used,  the  lamp  may  become  darker or  stop  working  before  the  lamp
warning  message  appears.  You  should  always  have  a  spare  lamp  unit  ready
in  case  it  is  needed.
How to replace the Lamp
The  Lamp  can  be  replaced  even  when  the  projector  is  suspended  from
a  ceiling.
 Warning
•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.•Never  disassemble  or  remodel  the  Lamp.  If  a  remodeled  or  reassembled
Lamp  is  installed  into  the  projector  and  used,  it  could  cause  a  fire,  electric
shock,  or  an  accident.

enough.ProcedureA
After  you  turn  off  the  projector's  power  and  the
confirmation  buzzer  beeps  twice,  disconnect  the  power  cable.
B
Wait  until  the  Lamp  has  cooled  down,  then  remove  the
Lamp  cover.
Loosen  the  Lamp  cover  fixing  screw  with  the  screwdriver  supplied
with  the  new  lamp  unit  or  a  +  head  screwdriver.  Then  slide  the
Lamp  cover  straight  forward  and  lift  it  to  remove.
