Shutting down the projector

The projector automatically blanks the screen after no active source is detected for 30 minutes. This blank screen helps preserve the life of the projector.

The image returns when an active source is detected or a remote or keypad button is pressed.

Screen Save

You can make the blank screen appear after five minutes by turning on Screen Save in the Settings>System menu. See page 22. There are six time options for the Screen Save feature. They range from five minutes to 30 minutes with five-minute intervals.

Power Save

The projector also has a Power Save feature that automatically turns the lamp off after no signals have been detected for five minutes. After three additional minutes with no signal, the projector powers down. If an active signal is

received before the projector powers down, the image is displayed. You must press the Power button to display an image after 30 minutes have passed. When Power Save is enabled, Screen Save is disabled. See page 22.

Turning off the projector

To turn off the projector, press the Power button. You can cancel the shutdown by pressing the power button again within 3 seconds. The lamp turns off and the LED blinks green for one minute while the fans continue to run to cool the lamp. When the lamp has cooled, the LED lights green and the fans stop. Unplug the power cable to completely power off the projector.
