Timing of replacing the lamp

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. See 
"Indicators" on page 90
 for details.
The following lamp warning displays will remind you to change the lamp.
The warning messages below are for reference only. Please follow the actual on-screen 
instructions to prepare and replace the lamp.
Install a new lamp for optimal performance. If the 
projector is normally run with Economic selected 
"Getting to know the lamp hour" on page 85
you may continue to operate the projector until 
the next lamp warning appears.
Press ENTER to dismiss the message.
It is strongly recommended that you replace the 
lamp at this stage. The lamp is a consumable item. 
The lamp brightness diminishes with use. This is 
normal lamp behavior. You can replace the lamp 
whenever you notice that the brightness level has 
significantly diminished.
Press ENTER to dismiss the message.
The lamp MUST be replaced before the projector 
will operate normally.
Press ENTER to dismiss the message.
