WARNINGS:

•To avoid burns, allow the projector to cool for at least 60 minutes before you replace the lamp.

•Do not drop the lamp module. The glass may shatter and cause injury.

•Do not touch the glass lamp screen. Fingerprints can obscure projection sharpness.

•Be extremely careful when removing the lamp housing. In the unlikely event that the lamp ruptures, small glass fragments may be generated. The lamp module is designed to contain most of these fragments, but use caution when removing it.

5Carefully remove the lamp module by grasping and lifting the metal bail wire. Dispose of the lamp in an environmentally proper manner.

6Install the new lamp module, making sure that it is properly seated.

7Tighten the three captive screws.

Resetting the lamp timer

If the lamp timer has reached the maximum number of hours for the projec- tor lamp, the LED on the projector’s keypad will show a lamp error (see “LED Behavior” on page 46). To reset the lamp timer, simultaneously press the decrease volume button and increase volume button on the keypad for 10 seconds. At that point the LED will turn green and you can power on the projector. You can also navigate to the Settings>Service menu and select Lamp Reset to reset the lamp timer.
