Replacing the projection lamp

The lamp hour timer in the About menu counts the number of hours the lamp has been in use. After 1,980 hours, the message “Change lamp” briefly appears on the screen at each startup. When the timer reaches 2,000 hours, the lamp will no longer light. You can order new lamp modules. See “Acces- sories” on page 38 for information.

1Turn off the projector and unplug the power cable.

2Wait 60 minutes to allow the projector to cool thoroughly.

3Turn the projector upside down and remove the lamp door by removing the two screws and sliding the lamp door tabs out of the three tab bays.

CAUTION: Never operate the projector with the lamp door removed. This disrupts the air flow and causes the projector to overheat.

4Loosen the captive screw on the lamp module.
