Replacing the projection lamp
The lamp hour timer in the About menu counts the number of hours the

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 from B

1 Turn off the projector and unplug the power cable.
2 Wait 60 minutes to allow the projector to cool thoroughly.
3 Turn 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.
