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. Status Message The lamp has been in operation for 2000 hours.
