¥Before replacing the lamp, press the POWER button to turn off the lamp and wait for 2 minutes for the lamp and LCD panels to cool down. Unplug the power cord from the wall outlet and wait 1 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 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.
