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 bulb ruptures, small glass fragments may be generated.
The lamp housing is designed to contain these fragments, but use cau-
tion when removing the lamp housing. Before replacing the lamp, clean
the lamp compartment and dispose of cleaning materials. Wash hands
after lamp replacement. This product has a lamp which contains a very
small amount of mercury. Dispose of it as required by local, state or fed-
eral ordinances and regulations. For more information see
www.eiae.org.
5 Carefully remove the lamp module by grasping and lifting the metal
bail wire. Dispose of the lamp in an environmentally proper manner.
6 Install the new lamp module, making sure that it is properly seated, and
tighten the three captive screws.
7 Replace the cover over the lamp module by inserting the tabs into the
tab bays and pushing the rest of the cover down into place.
8 Plug in the power cable, press the power switch then press the Power
button to turn the projector back on. Reset the lamp hour timer.
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 44). 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.
