Connecting a video deviceYou can connect video devices such as VCRs, DVD players, camcorders, 
digital cameras, video game consoles, HDTV receivers, and TV tuners to the 
projector. There is also an audio input via the red and white A/V connec
-
tors. You can connect the audio directly to the projector to get sound from 
the built-in speaker, or you can bypass the projector ’s audio system and 
connect the audio directly from your source to a stereo or home theater sys
-
tem.You can connect the projector to most video devices that can output video. 
You cannot directly connect the coaxial cable that enters your house from a 
cable or satellite company, the signal must pass through a tuner first. Exam
-
ples of tuners are digital cable boxes, VCRs, digital video recorders, and sat
-
ellite TV boxes. Basically, any device that can change channels is considered 
a tuner.Before connecting your projector, you should decide which aspect ratio you 
want to use. The projector ’s Aspect Ratio setting is accessed through the 
projector ’s Picture Menu. See 
page
 28 for more information.
What is Aspect Ratio?Aspect ratio is the ratio of the image width to image height. TV screens are 
usually 4:3, which is the default for this projector. HDTV and most DVDs 
are 16:9. If you’re projecting onto a screen, the size/shape of the screen may 
determine which aspect ratio to use. If you are projecting onto a blank wall, 
you don’t have the screen size restriction. What you plan to project will also 
help you choose between 4:3 and 16:9. Most TV shows are 4:3, while most 
movies are 16:9.If you have a 16:9 screen then you should select an aspect ratio of 16:9 for 
anamorphic movies or HDTV, and Native for 4:3 content. If you have a 4:3 
screen you should still use 16:9 for anamorphic movies or HDTV, but you 
also have the option of using either 4:3 (to fill the screen) or Native (for 
direct pixel mapping) for 4:3 content. Keep in mind that anamorphic movies 
only appear correctly if the DVD player is set to output to a 16:9 television.

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
 31.
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
 31.
Turning off the projectorTo turn the projector off, press the Pow e r button on the remote or keypad 
two times (the second time verifies the shut-down request). The lamp turns 
off and the Power light on the Status Indicator Panel blinks green for one (1) 
minute while the fans continue to run to cool the lamp. While the light is 
blinking green, the projector does not accept any keypad and remote control 
input. When the lamp has cooled, the Power light is solid green. 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 
projector and can help you troubleshoot
