Lamp replacement
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 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.

Interval of lamp replacement
The recommended interval of lamp replacement is about 5000 hours*1, *2 of consecutive use. Such interval differs depending on the operating environment and may be shorter than 5000 hours*1, *2. Decrease in luminescence and/or color brightness indicates that the lamp needs to be replaced. When the lamp operation time exceeds 3750 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 blink red only) and the lamp replacement message will appear on the screen for one minute every time the lamp is turned on. When the lamp has been used for about 4750 hours*1, the replacement message (LAMP EXCHANGE) will appear on the screen for one minute every 25 hours*1 thereafter.
When the lamp operation time exceeds 5000 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.
For XD480U / XD450U only
*1 When LAMP MODE of the INSTALLATION menu is set to LOW. When it is set to STANDARD, this dura- tion will be shortened.
*2 When LAMP MODE is set to STANDARD, this dura- tion will be shortened to 2000 hours.
