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 

 for details.

The following Lamp warning displays will remind you to change the lamp.

The lamp has been in operation for 3000 hours. 
Install a new lamp for optimal performance. If the 
projector is normally run with Eco. selected (See 

), you 

may continue to operate the projector until the 
3950 hour lamp warning appears.

replaced beforehand, it should be replaced after 
3950 hours usage.
