Lamp Information
Warning Message
When the Lamp indicator lights up red or a message appears suggesting it is time to replace 
the lamp, please install a new lamp or consult your dealer. An old lamp may cause a mal-
function in the projector and in some instances the lamp may explode.
For more detailed information on lamp warnings, please refer to page 32.
The Lamp indicator light and Temperature warning light will light up if the lamp becomes too
hot. Turn the power off and let the projector cool for 45 minutes. If the Lamp or Temp indicator
still lights up after turning the power back on, please contact your dealer.
The following Lamp warning displays will remind you to change the lamp. 
The out of lamp time warning is calculated on normal mode operation. If the projector is run in
Economic mode the allowable lamp time is 3000 hours. If the projector is used in both normal
and Economic modes then the allowable lamp time is calculated at a rate of 66% while the
Economic mode is active. In this case the out of lamp time warning will occur between 2000
and 3000 hours depending on the percentage of Economic mode usage.
Replacing the Lamp
To reduce the risk of electrical shock, always turn the projector off and disconnect the power
cord before changing the lamp.   
To reduce the risk of severe burns, allow the projector to cool for at least 45 minutes before
replacing the lamp.
To reduce the risk of injuries to fingers and damage to internal components, use caution when
removing lamp glass that has shattered into sharp pieces.
