Shutting down the projectorBy default, the projector automatically displays a blank 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 a different time interval using 
the Settings>System menu. See page 32. There are six time options, rang-
ing from five minutes to 30 minutes with five minute intervals.
Powe r  S av e
The projector also has a Power Save feature that, when activated, automati-
cally turns the lamp off after no signals are detected for 20 minutes. After 10 
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 31.
Turning off the 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. When the 
lamp has cooled, the LED lights green. Unplug the power cable to com-
pletely power off the projector.
Troubleshooting your setupIf your image appears correctly on the screen, skip to the next section 
(page 23). If it does not, troubleshoot the setup. 
The Interactive Display and LED on top of the projector indicate the state of 
the projector and can help you troubleshoot.
