Lamp information
Calculation of lamp hour
When the projector is in operation, the duration (by hours) of lamp usage is automatically calculated by the
Total (equivalent) lamp hour = hours used in Economic mode + hours used in normal mode
See "Economic Mode (off)" on page 34 for more information on Economic mode.
The lamp hour in Economic mode is calculated as 3/4 of that in normal mode. That is, using the projector in Economic mode helps to extend the lamp hour by 1/4.
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 malfunction in the projector and in some instances the lamp may explode.
For more detailed information on projector warnings, please refer to "Indicators" on page 41.
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.
