Lamp replacement

The lamp is designed to project the image on the LCD panels. When the lamp no longer functions, replace it with a new one.

Caution:

Do not remove the lamp immediately after using the projector. You may get burned because the lamp is very hot after use.

Before replacing the lamp, press the POWER button to turn off the lamp and wait for two minutes for the lamp and LCD panels to cool down. Unplug the power cord from the wall outlet and wait one hour for the lamp to cool down completely.

Do not remove the lamp except for replacement. Careless handling can cause injury or fire.

Do not touch the lamp directly. It may break and cause injury or burn.

Be sure not to drop the lamp lid screw into the projector. Also be sure not to put metal or any flammable objects inside because it may cause fire or electric shock. If any objects should fall inside, unplug and contact your dealer.

Install the lamp securely to prevent failure and fire.

If the lamp should break, small glass fragments may fall out through the grilles and some may remain inside of the projector or the lamp box. When taking the lamp box out, be sure to turn over the projector and hold the handle of the lamp box to avoid injury due to the glass fragments.

If the lamp should break, never shake the lamp box or hold it in front of your face after removing it. The glass fragments may fall out and cause injury to your eyes.

Reset of the lamp operation time

Plug in the power cord, turn on the

lamp, and reset the lamp operation time by keep pressing the $, %, and POWER buttons on the control panel at the same time about three seconds.

Important:

Unless these three buttons are pressed at the same time, the lamp operation time isn’t reset.

Make sure that the STATUS indicator is lit twice and the lamp operation time is reset successfully.

The projector doesn’t turn on if the lamp cover isn’t attached securely.

Be sure to reset the lamp operation time when- ever you replace the lamp.

Do not reset the lamp operation time unless you replace the lamp.

Caution:

The lamp is fragile. If it is broken, be careful not to cut yourself with glass fragments.

Contact your dealer for a new lamp.

Interval of lamp replacement

The recommended interval of lamp replacement is about 2,000 hours of consecutive use. Such interval differs depending on the operating environment and may be shorter than 2,000 hours. Decrease in lumi- nescence and/or color brightness indicates that the lamp needs to be replaced. When the lamp operation time exceeds 1,500 hours*1, the indicator will blink alternately between green and red (while the lamp is lit; when the lamp is not lit, the indicator will be lit red only) and the lamp replacement message will appear on the screen for one minute everytime the lamp is turned on. When the lamp has been used for about 1,900 hours*1, the replacement message (LAMP:>1900H) will appear on the screen for one minute every 10 hours thereafter.

When the lamp operation time exceeds 2,000 hours*1 *2, the projector automatically shuts off and can’t be used until the lamp is replaced and the lamp operation time is reset.

*1 When LAMP MODE of the INSTALLATION menu is set to STANDARD.

*2 When LAMP MODE is set to LOW, this duration will be extended up to 5,000 hours.

Caution:

This projector uses a lamp that contains mercury. Disposal of the lamp or the projector with the lamp may be regulated due to environmental considerations. For disposal or recycling informa- tion, please contact your local authorities or the Electronic Industries Alliance: www.eiae.org. (For US only).
