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 otherthan 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 the projector near a smoky, humid or dusty place (ex. asmoking space, a kitchen, a beach, etc.). Do not place the projector outdoors.•Do not use a humidifier near the projector.
Take care of the air filter to normal ventilate.
The air filter should be cleaned periodically. If the air filter becomes clogged bydust or the like, internal temperature rises and could cause malfunction. 
Theprojector may display the message such as “CHECK THE AIR FLOW” orturn off the projector, to prevent the internal heat level rising.• When the indicators or a message prompts you to clean the air filter, clean theair filter as soon as possible. •If the soiling will not come off the air filter, or it becomes damaged, replace theair 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.

Manufacture strongly recommends to avoid any magnetic contact that is not shielded or protected  on or near the projector itself.  (ie.,. Magnetic Security 
Devices,or other projector accessory that contains magnetic material that has not been provided by the manufacture etc.) Magnetic objects may cause interruption ofthe projector's internal mechanical performance which may interfere with cooling fansspeed or stopping, and may cause the projector to completely shut down. 
						

							 Safety Precautions (continued)
NOTE
Do not give the remote control any physical impact.
Aphysical impact could cause damage or malfunction of the remote control.• Take care not to drop the remote control.• Do not place the projector or heavy objects on the remote control.
Take care of the lens.
•  Close the slide lens door or attach the lens cap to prevent the lens surface being scratched when the projector is not used.• Do not touch the lens to prevent fog or dirt of the lens that cause deterioration of display quality.• Use commercially available lens tissue to clean the lens (used to clean cameras, eyeglasses, etc.).

Disconnectthe plug from the power outlet. 
						

							 Safety Precautions (continued)
NOTE
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.•This product isn’t designed for continuous use of long time. In the case of continuous use for  hours or more, or use for   hours or more every day (even if it isn’t continuous), or repetitious use, the lifetime may be shortened, and these parts may need to be replaced evenif one year has not passed since the beginning of using.• Any inclining use beyond the adjustment range explained in these user’s manuals may 
shorten the lifetimes of the consumables.
Before turning on the power, make the projector cool down adequately.
After turning the projector off, pushing the restart switch or interrupting of the power supply, makethe projector cool down adequately. Operation in a high temperature state of the 
projector causes a damage of the electrode and un-lighting of the lamp.
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.
Anyinterfering radiation could cause disordered image or noises.• Avoid radio generator such as a mobile telephone, transceiver, etc. around the projector.
About displaying characteristic.
T h e d i s p l a y c o n d i t i o n o f t h e p r o j e c t o r ( s u c h a s c o l o r, c o n t r a s t , e t c . ) d e p e n d s o n 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 specifying.•Power on the projector before the computer or video tape recorder.• Power off the projector after the computer or video tape recorder.
Take care not to fatigue your eyes.
Rest the eyes periodically.
Set the sound volume at a suitable level to avoid bothering other people\
.
•  It is better to keep the volume level low and close the windows at night to protect the neighborhood environment.
Connecting with notebook computer
When connecting with notebook computer, set to valid the RGB external image output (setting CRT display or simultaneous display of LCD and CRT).Please read instruction manual of the notebook for more information. 
						

							• If the lamp should break (it will make a loud bang when it does), unplug thepower cord from the outlet, and make sure to request a replacement lampfrom 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 theroom 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 minutes for the lamp to cool sufficiently. Handling the lamp while hot can cause burns, as well as 
damaging the lamp.
 Lamp
The projector uses a high-pressure mercury glass lamp. The lamp can break  with  a loud  bang,  or  burn  out,ifjolted or scratched, handled while hot, or worn over time. Notethat each lamp has a different lifetime, and some may burst or burn out soon after youstart using them. In addition, when the bulb bursts, it is possible for shards  of glasstofly into the lamp housing, and for gas containing mercurytoescape 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) Forproduct disposal, contact your local government agency or www.eiae.org (in the US) orwww.epsc.ca (in Canada). Formore information, call your dealer.
• Do not open the lamp cover while the projector is suspended from above. Thisis dangerous, since if the lamp’s bulb has broken, the shards will fallout 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 couldresult 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, contactyour local dealer or a service representative.• Handle with care: jolting or scratching could cause the lamp bulb to burst during use.• Using the lamp for long periods of time, could cause it dark, not to light up orto burst. When the pictures appear dark, or when the color tone is poor, please replace the lamp as soon as possible. Do not use old (used) lamps; thisis a cause of breakage.
