connector on the video device. Plug the other yellow connector into the yel-
low Video 3 connector on the projector. Plug a white connector into the left 
audio out connector on the video device and plug a red connector into the

S-video cable (sold separately) into the S-video connector on the video 
device and into the Video 2 connector on the projector. Use the A/V cable’s 
audio connectors as described directly above (the yellow connectors on the 
A/V cable are not used).
If the video device uses component cable connectors (sold separately), plug 
the cable’s green connectors into the green component-out connector on the 
video device and into the Video 1 green component connector (labeled “Y”) 
on the projector. Plug the component cable’s blue connectors into the blue

nectors on the A/V cable are not used). NOTE: The component connectors 
can be used for HDTV sources (480i, 480p, 720p, 576i and 1080i formats).

Shutting down the projectorThe projector automatically blanks the screen after no active source is 
detected for 5 minutes. This blank 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 blank screen appear after five minutes by turning on 
Screen Save in the Settings>System menu. See page 32.
Pow e r  S av e
The projector also has a Power Save feature that automatically 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 32.
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 Power light blinks green for over 1 minute 
while the fans continue to run to cool the lamp. When the lamp has cooled, 
the Power light is solid green and the fans stop. Press the power switch on 
the back of the projector and unplug the power cable to completely power 
off the projector.Troubleshooting your setupIf your image appears correctly on the screen, skip to the next section. If it 
does not, troubleshoot the setup. The Status Indicator Panel on top of the projector indicates the state of the
