Adjusting the image
If necessary, adjust the height of the projector by rotating the elevator foot to extend the 
foot.
If necessary, rotate the leveling foot located at the rear of the projector.
Avoid placing your hands near the hot exhaust vent at the front of the projector.
Position the projector the desired distance from the screen at a 90 degree angle to the 
screen.
See page 7 for a table listing screen sizes and distances.
Adjust the zoom or focus.
If the image is not square, first make sure that the projector is perpendicular to the screen. If 
the image is larger or smaller on the top or bottom edge of the screen, press the top 
Keystone button  to reduce the upper part of the image, and press the bottom 
Keystone button  to reduce the lower part.
If the left or right side of the screen is larger or smaller the other, you can turn the projector 
to the left or to the right a few degrees to square the image.
Adjust the Contrast or Brightness in the Basic Menu. See page 26 for help with these menu adjustments.

Connecting a video device
You can connect video devices such as VCRs, DVD players, camcorders, digital cameras, 
video game consoles, HDTV receivers, and TV tuners to the projector. 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 system.
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. Examples of tuners are digital cable boxes, VCRs, 
digital video recorders, and satellite 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 Resize button on the remote or 
through the projector’s Basic Menu. See 
page 26 for more information.
Video device connections
No video cables are provided with the projector. You can order cables from InFocus or 
provide your own.
HDMI connection
HDMI is a standard, uncompressed, all-digital audio/video interface. HDMI provides an 
interface between sources, such as set-top boxes, DVD players, and receivers and your 
projector. Plug an HDMI cable into the video-out connector on the video device and into the 
HDMI connector on the projector.
Composite video connection
Plug the composite video cable’s yellow connector into the video-out connector on the 
video device. Plug the other yellow connector into the yellow Video connector on the 
projector.
VGA connection
If your video device has a 15-pin VGA output, plug one end of the included computer cable 
into the VGA connector on your video source. This connector may be labeled “To Monitor” 
on the video source. Plug the computer cable into either the Computer 1 or Computer 2 
connector on the projector.
Component video connection
If your HD video device has component connectors, an optional Component to VGA 
adapter can be used. Plug the component cable into the video device. Plug the other end of 
the component cable into the adapter and plug the adapter into the 
Computer 1 or 
Computer 2 connector.
S-video connection
Plug the S-video cable’s connector into the video-out connector on the video device. Plug 
the other connector into the S-Video connector on the projector.
Audio
For audio, connect a 3.5mm stereo cable to the Audio 1/Audio 2 connector on the projector 
and to your source. If your source uses RCA audio connectors, a Y-cable or adapter may be 
used. (Note: A separate audio connection is not required for HDMI source inputs.)

Shutting down the projector
Auto Off Time
The projector also has an Auto Off Time feature that automatically turns the projector off 
after no active sources are detected and no user interaction with the projector is performed 
for 30 minutes. By default, this feature is off. You can change the length of time, see 
page 30.
Turning off the projector
To turn the projector off, press the Power button on the remote or keypad. The lamp turns 
off and the Power LED blinks blue for 30 seconds while the fans continue to run to cool the 
lamp. If the Power Saving Mode feature is on and when the lamp has cooled, the LED lights 
blue and the fans stop. If the Power Saving Mode feature is off and when the lamp has cooled, 
the LED blinks blue and the fans stop. Unplug the power cable to completely power off the 
projector.
Troubleshooting your setup
If your image appears correctly on the screen, skip to the next section. If it does not, 
troubleshoot the setup.
The Status Indicator Lights on top of the projector indicates the state of the projector and 
can help you troubleshoot.
