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 6 hours or more, or use for 6 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

even if 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,

make the 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.

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

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

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.

Lamp

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 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.

• 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.

• Using the lamp for long periods of time, could cause it dark, not to light up

or to 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;

this is a cause of breakage.
