Shutting down the projector
The projector automatically displays a black screen after no active source is
detected for 30 minutes. This black screen helps preserve the life of the pro-
jector. The image returns when an active source is detected or a remote or
keypad button is pressed.
Screen Save
You can make the black screen appear after a preset number of minutes by
turning on the Screen Save feature in the Settings>System menu. See
page 32.
Power Save
The projector also has a Power Save feature that automatically turns the
lamp off after no active sources are detected and no user interaction with
the projector is performed for 20 minutes. By default, this feature is off. See
page 32.
Turning off the projector
You can turn the projector off simply by toggling the power switch to the off
position.
You can also press the remote's Power button to place the projector in the
Off state while it is running. When the Power button is pressed twice (once
to start the power-down process and a second time to verify that you want
to power 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 keypad and remote
control input.
When the lamp has cooled, the LED lights solid green and the fans slow
down to minimal speed. To turn off the projector, toggle the power switch to
the off position.
NOTE: Once the projector has been toggled off, you must wait for one (1)
minute before turning the projector on again. This allows the lamp to prop-
erly cool. However, if the remote was used to power the projector to the Off
state you do not need to wait one minute to turn it on again.
Troubleshooting your setup
If your image appears correctly on the screen, skip to the next section. If it
does not, troubleshoot the setup.
The LED on top of the projector indicates the state of the projector and can
help you troubleshoot.
