Turning off the projector

Press the Power button on the remote or keypad to turn the projector off. The lamp turns off and the LED blinks green for one (1) minute while the fans continue to run to cool the lamp. While the LED is blinking green, the projector does not accept any user input. Once the cooling process is com- plete, the LED lights solid green and you can turn the projector back on, if desired.

NOTE: Once the projector has been turned off, you must wait for one (1) minute before turning the projector on again. This allows the lamp to prop- erly cool. The LED lights solid green when the cooling process is complete.
