Shutting down the projectorThe 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 SaveYou 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 38.Pow e r  S av eThe 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 38.Turning off the projectorYou can turn the projector off simply by toggling the power switch to the off 
position.
You can also press the remote’s Pow e r button to place the projector in the 
Off state while it is running. When the Pow e r 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 setupIf 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. 
The following tables show common problems. In some cases, more than one 
possible solution is provided. Try the solutions in the order they are pre-
sented. When the problem is solved, you can skip the additional solutions.
