 WARNING HIGH VOLTAGE HIGH TEMPERATURE HIGH PRESSURE
►The  projector  uses  a  high-pressure  mercury  glass  lamp.  The  lamp  can break 
with  a  loud  bang,  or  burn  out,  if  jolted  or  scratched,  handled  while  hot,  or  worn 
over  time.  Note  that  each  lamp  has  a  different  lifetime,  and  some  may  burst  or 
burn  out  soon  after  you  start  using  them.  In  addition,  when  the  bulb  bursts,  it  is 
possible  for  shards  of  glass  to  fly  into  the  lamp  housing,  and  for  gas  containing 
mercury to escape from the projector’s vent holes.
►About disposal of a lamp  • This product contains a mercury lamp; do not 
put in trash. Dispose of in accord with environmental laws.
For lamp recycling, go to www.lamprecycle.org. (in the US) 
For product disposal, contact your local government agency or www .eiae.org (in 
the US) or www.epsc.ca (in Canada). 
For more information, call your dealer.
• If  the  lamp  should  break  (it  will  make  a  loud  bang  when  it  does), 
unplug  the  power  cord  from  the  outlet,  and  make  sure  to  request  a 
replacement  lamp  from  your  local  dealer.  Note  that  shards  of  glass 
could damage the projector’s internals, or cause injury during handling, 
so please do not try to clean the projector or replace the lamp yourself.
•  If  the  lamp  should  break  (it  will  make  a  loud  bang  when  it  does), 
ventilate  the  room  well,  and  make  sure  not  to  breathe  the  gas  that 
comes out of the projector vents, or get it in your eyes or mouth.
• Before replacing the lamp, turn the projector off and unplug the power 
cord,  then  wait  at  least  45  minutes  for  the  lamp  to  cool  sufficiently. 
Handling  the  lamp  while  hot  can  cause  burns,  as  well  as  damaging  the 
lamp.
• Never unscrew except the appointed (marked by an arrow) screws.
•  Do  not  open  the  lamp  door  while  the  projector  is  suspended  from 
above.  This  is  dangerous,  since  if  the  lamp’s  bulb  has  broken,  the 
shards  will  fall  out  when  the  cover  is  opened.  In  addition,  working  in 
high  places  is  dangerous,  so  ask  your  local  dealer  to  have  the  lamp 
replaced even if the bulb is not broken.
•  Do  not  use  the  projector  with  the  lamp  door  removed.  At  the  lamp 
replacing,  make  sure  that  the  screws  are  screwed  in  firmly.  Loose 
screws could result in damage or injury.
• Use only the lamp of the specified type.
•  If  the  lamp  breaks  soon  after  the  first  time  it  is  used,  it  is  possible 
that  there  are  electrical  problems  elsewhere  besides  the  lamp.  If  this 
happens, contact your local dealer or a service representative.
• Handle with care: jolting or scratching could cause the lamp bulb to burst during use.•  If  the  indicators  or  a  message  prompts  you  to  replace  the  lamp  (see 
the  section  "Related  Messages"  and  "Regarding  the  indicator  Lamps"), 
replace  the  lamp  as  soon  as  possible.  Using  the  lamp  for  long  periods 
of  time,  or  past  the  replacement  date,  could  cause  it  to  burst.  Do  not 
use old (used) lamps; this is a cause of breakage.
Disconnect the plug from the power outlet

lamp as soon as possible.
1. Turn the projector off, and unplug the power cord. Allow the lamp to cool for 
at least 45 minutes.
2. To prepare a new lamp, contact your dealer and tell the lamp type number = 
78-6969-9812-5.  If the projector is mounted on the ceiling, or if the lamp has 
broken, also ask the dealer to replace the lamp.
In the case of replacement by yourself,
3. After making sure that the projector has cooled 
adequately, slowly turn over the projector, so 
that the bottom is facing up.
4. Please loosen the screw (marked by arrow). Then, 
unhook the claws of the lamp door and remove the 
lamp door.
5. Loosen the 2 screws (marked by arrow) of the lamp, 
and slowly pick up the lamp by the 
handles.
6. Insert the new lamp, and retighten 
firmly two screws that are loosened

using the LAMP TIME function of OPTION 
menu (39).
NOTE
  • When the lamp has been replaced after the message of "THE 
POWER WILL TURN OFF AFTER 0hr." is displayed, complete the following 
operation within 10 minutes of switching power on.
• Incorrectly resetting of the lamp timer (resetting without replacement, or  neglect of resetting after replacement) will result in incorrect message functions.

Maintenance
When  the  indicators  or  a  message  prompts  you  to  clean  the  air  filter,  clean  the 
air  filter  as  soon  as  possible.  If  the  air  filter  becomes  clogged  by  dust  or  the  like, 
internal  temperatures  rise  and  the  power  may  be  automatically  turned  off  for 
malfunction prevention.
1. Disconnect all the connectors and adapters that were connected to the 
projector’s ports. Then slowly turn the projector so that the lens-side is facing 
up. Please be careful for a projector not to fall. While the projector is placed 
lens-side up, hold the projector.
2. Remove the filter cover and the air filter. Hold the knobs while pulling out it.
3. Apply a vacuum cleaner to the vent of the projector for the air filter. And then 
slowly turn the projector bottom up.

fact that, after long hours of usage, a lamp will no longer light up, or the lamp 
will break or burst, etc. This projector is equipped with an automatic shut-down 
function, such that the power will automatically be turned off when lamp usage 
time has reached 2000 hours. Please be aware, however, that among lamp 
types, there are major differences in product lifetimes; a lamp may thus fail to 
light even prior to the functioning of the automatic shut-down function of this 
projector.
