power  cord  and  all  external  connections,  and  close  the  slide  lens  door  or
attach the lens cap.
• Avoid any impact or shock to the projector. 
• Do not drag the projector.
• For moving the projector, use the enclosed case or bag if provided.
Do not put anything on top of the projector.
Placing  anything  on  the  projector  could  result  in  loss  of  balance  or  falling,
and  cause  an  injury  or  damage.  Use  special  caution  in  households  where
children are present.
Do not attach anything other than specified things to the projector.
Neglect could result in an injury or damage.
• Some  projector  has  a  screw  thread  in  a  lens  part.  Do  not  attach  anything
other than specified options (such as conversion lens) to the screw thread.
Avoid a smoky, humid or dusty place.
Placing  the  projector  in  a  smoke,  a  highly  humid,  dusty  place,  oily  soot  or
corrosive gas could result in fire or electrical shock. 
• Do not place near the smoking space, the kitchen or a humidifier.
Take care of the air filter to normal ventilate.
The  air  filter  should  be  cleaned  periodically.  If  the  air  filter  becomes
clogged  by  dust  or  the  like,  internal  temperature  rises  and  could  cause
malfunction. The projector may display the message such as “CHECK THE
AIR  FLOW”  or  turn  off  the  projector,  to  prevent  the  internal  heat  level
rising.
• When the indicators or a message prompts you to clean the air filter, clean
the air filter as soon as possible. 
•  If  the  soiling  will  not  come  off  the  air  filter,  or  it  becomes  damaged,
replace the air filter.
•  Use  the  air  filter  of  the  specified  type  only.  Please  order  the  air  filter
specified in the other manual of this projector to your dealer. 
• When you replace the lamp, replace also the air filter. The air filter may be
attached when you buy a replacement lamp for this projector.

Incorrect care could have adverse influence such as discoloration, peeling paint, etc.
•  Use  a  soft  cloth  to  clean  the  cabinet  and  control  panel  of  the  projector  and  the  remote
control. When excessively soiled dilute a neutral detergent in water, wet and wring out the
soft  cloth  and  afterward  wipe  with  a  dry  soft  cloth.  Do  not  use  undiluted  detergent
directly.
• Do not use an aerosol sprays, solvents, volatile substances or abrasive cleaner.
• Before using chemical wipes, be sure to read and observe the instructions.
• Do not allow long-term close contact with rubber or vinyl.
About bright spots or dark spots.
Although bright spots or dark spots may appear on the screen, this is a unique characteristic of
liquid crystal displays, and such do not constitute or imply a machine defect.
Be careful of printing of the LCD panel.
If  the  projector  continues  projecting  a  still  image,  inactive  images  or  16:9  aspect  images
in case of 4:3 panel, etc., for long time, the LCD panel might possibly be printed. 
In such a case, please make the projector project a whole white screen for 1 hour or more.
You can use the BLANK function of the projector. 
About consumables. 
Lamp,  LCD  panels,  polarizors  and  other  optical  components,  and  air  filter  and  cooling
fans  have  a  different  lifetime  in  each.  These  parts  may  need  to  be  replaced  after  a  long
usage time, even if one year has not passed since the beginning of using. For more details,
please consult your dealer.
CAUTION
Ask your dealer to cleaning inside of the projector about every two
years.
Accumulations  of  dust  inside  the  projector  cause  result  in  fire  or
malfunction.  Cleaning  inside  is  more  effective  if  performed  before  every
humid periods such as rainy season.
• Do not clean inside yourself because it is dangerous.

Safety Precautions (continued)
NOTE
Avoid strong rays.
Any strong ray (such as direct rays of the sun or room lighting) onto the remote control
sensors could invalidate the remote control. 
Avoid radio interference.
Any interfering radiation could cause disordered image or noises.
• Avoid radio generator such as a mobile telephone, transceiver, etc. around the projector.
About displaying characteristic.
The  display  condition  of  the  projector  (such  as  color,  contrast,  etc.)  depends  on
characteristic  of  the  screen,  because  the  projector  uses  a  liquid  crystal  display  panel.  The
display condition can differ from the display of CRT.
• Do not use a polarized screen. It can cause red image.
Turn the power on/off in right order.
To  prevent  any  trouble,  turn  on/off  the  projector  in  right  order  mentioned  below  unless

							Lamp
8The  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
glassto fly into the lamp housing, and for gas containing mercuryto 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 USA) 
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, make sure the power switch is off and the
power cable is not plugged in, 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.
• Do not open the lamp cover 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 cover removed. At the lamp
replacing, make sure that the screws are screwed in firmly. Loose screws
could result in damage or injury.
• Use the lamp of the specified type only.
• 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.
