Locate the projector in a well-ventilated area without any obstructions to intake or exhaust vents. Do not place the projector on a tablecloth or other soft covering that may block the vents. vesa 1 dv1 2 serial Do not place objects or people in the 2 foot (.6m) area along the side of the projector. For ceiling mount applications, this area should be 5 feet (1.5m). · · · · · Locate the projector at least 4' (1.2 m) away from any heating or cooling vents. Use only InFocus-approved ceiling mounts. The minimum distance between the ceiling and a ceiling-mounted projector is 11.8"/30cm. Use only the power cord provided. A surge-protected power strip is recommended. Refer to this manual for proper startup and shutdown procedures. In the unlikely event of the lamp rupturing, discard any edible items placed in the surrounding area and thoroughly clean the area along all sides of the projector. Wash hands after cleaning the area and handling the ruptured lamp. This product has a lamp which contains a very small amount of mercury. Dispose of it as required by local, state or federal ordinances and regulations.

The Command Line Interface (CLI) specifications and commands are on our website. A 3.5mm mini-jack trigger provides 12 volt current. This provides a constant output while the projector is on. For example, if you connect your projection screen to the trigger, when you turn on the projector the screen will move down; when you turn the projector off, the screen will return to the storage position. You must turn the trigger on in the System menu, see page 28. +12v ground 3.5mm mono plug for 12 volt current connection RS232 serial control composite video lock power connector to screen relay (see screen manufacturer for details) 5 Positioning the projector There are a number of factors to consider when determining where to set up the projector, including the size and shape of your screen, the location of your power outlets, and the distance between the projector and the rest of your equipment. Here are some general guidelines. 1 Position the projector on a flat surface at a right angle to the screen. The projector must be within 10 feet (3 m) of your power source. To ensure adequate cable access, place the projector at least 6 inches (0.15m) from a wall or other objects. Place the projector at least 5.6 feet (1.7 m) from the projection screen. If you install the projector on the ceiling, refer to the installation guide that comes with the Ceiling Mount Kit for more information. To turn the image upside down, see page 28. InFocus recommends use of an authorized InFocus ceiling mount. The Ceiling Mount Kit is sold separately. 10' high image 2 Position the projector the desired distance from the screen. The distance from the lens of the projector to the screen, the zoom setting, and the video format determine the size of the projected image. For more information about projected image sizes, see page 36. The image exits the projector at a given angle. This image offset is 105%. This means that if you have an image 10' high, the bottom of the image will be 0.5' above the center of the lens. Go to www.infocushome.com/support for a complete image size calculator. bottom of image 0.5' above lens lens center 6 Video connections You can connect VCRs, DVD players, camcorders, digital cameras, video games, HDTV receivers, and TV tuners to the projector. (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.) If there is more than one output, select the highest quality one. DVI, Component video and RGB (M1, HD15) have the best quality, followed by S-video, and then composite video.

DVI video has the best quality, followed by Component video, S-video, and then composite video. If the video device uses component cable connectors, plug the cable's green connectors into the green component-out connector on the video device and into the green component connector (labeled "Y" Component 3) on the projector. Plug the component cable's blue connectors into the blue component-out connector on the video device and into the blue component connector (labeled "Pb") on the projector. Plug the component cable's red connectors into the red component-out connector on the video device and into the red component connector (labeled "Pr") on the projector. If you are using RGB input, plug the additional connector into the Video 5 connector and turn on the RGB Video option in the Sources menu. See page 28. If the video device uses a round, four-prong S-video connector, plug the S-video cable into the S-video connector on the video device and into the SVideo 4 connector on the projector. Connect the red and white audio connectors from the A/V cable to your source and Audio In connector on the projector, if desired. If the video device uses a yellow composite video connector, plug the A/V cable's yellow connector into the video-out connector on the video device. Plug the other yellow connector into the yellow Video 5 connector on the projector. Connect the red and white audio connectors from the A/V cable to your source and the projector. If the video device uses a DVI connector, plug the computer cable into the video-out connector on the video device. Plug the other connector into the DVI 2 connector on the projector. If the video device uses a VESA connector, plug a VESA cable into the video-out connector on the video device. Plug the other connector into the VESA 1 connector on the projector. connect component cable serial control Y Pb Pr audio in trigger connect S-video cable serial control Y Pb Pr audio in trigger connect composite video cable serial control Y Pb Pr audio in trigger connect M1-D cable Y Pb Pr audio in trigger serial control connect VESA cable Y Pb Pr audio in trigger serial control Connecting the power cable Connect the power cable to the connector on the back of the projector and to your electrical outlet.

This blank screen helps preserve the life of the projector. 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 29. There are six time options for the Screen Save feature. They range from five minutes to 30 minutes with five minute intervals. Power Save The projector also has a Power Save feature that automatically turns the lamp off after no signals are detected for 5 minutes. After 3 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 29. Turning off the projector To turn off the projector, press the Power button. You can cancel the shutdown by pressing the Power button again within 3 seconds. The lamp turns off and the LED blinks green for 1 minute while the fans continue to run to cool the lamp. When the lamp has cooled, the LED lights green 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 (page 20). 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. Table 2: LED behavior and meaning LED color/behavior solid green Meaning The projector is plugged in, or the projector has been turned off and the fans have stopped. The projector is powering down and the fans are running to cool the lamp. A fan or lamp failure has occurred. Make sure the vents aren't blocked (see page 17).

Contrast: controls the degree of difference between the lightest and darkest parts of the picture and changes the amount of black and white in the image. Brightness: changes the intensity of the image. Color: (video and component sources only) adjusts a video image from black and white to fully saturated color. Tint: (NTSC video sources only) adjusts the red-green color balance in the image. Aspect Ratio: Aspect ratio is the ratio of the image width to image height. TV screens are usually 1.33:1, also known as 4:3. HDTV and most DVDs are 1.78:1, or 16:9. The default is16:9. Native: this mode bypasses the internal scaler, displaying the image with no resizing. Since the native resolution is 1280x720 and 4x3 video images are approximately 640x480, 4x3 images will always be smaller than the display and will be centered in the display. Computer images 1024x768 or smaller will also be centered in the display.
