lish Timing of replacing the lamp
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.
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. See
"Indicators" on page 47 for details.
The following Lamp warning displays will remind you to change the lamp.
