This is an additional information tip to clarify the "Turn off the projector" steps as referenced on page 18 of the Users guide for the iLC300 Conference Room Data/Video Projector.

To turn off the projector, press the power button and verify that you want to turn the projector off by pressing the power button again within 3 seconds. You can cancel the shutdown by not pressing the power button a second time. The lamp turns off and the LED blinks green for 1 minute while the fans continue to run to cool the lamp. When the LED light is solid green and the fans have stopped, the lamp has cooled. At that time, unplug the power cable to completely power off the projector.
