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.
