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. Locate the projector at least 4' (1.2 m) away from any heating or cooling vents. Use only InFocus-approved ceiling mounts. Use only the power cord provided. A surge-protected power strip is recommended. Refer to this guide for proper startup and shutdown procedures. · · · · · · Warning: Hg ­ Lamp contains mercury. Manage in accordance with local disposal laws. See www.lamprecycle.org. In the unlikely event of a lamp rupture, particles may exit through the projector side vents. When the projector is turned on, keep people, food, and drinks out of the "keep out" area under and around the projector, as indicated by the "X" areas below. Follow these instructions to help ensure image quality and lamp life over the life of the projector. Failure to follow these instructions may affect the warranty. For complete details of the warranty, see the Warranty booklet. 8' / 2 .4 m 2 2' 3' / 1 m /0 .6 m / 5' m 1.5 3' / 1 m Introduction Your new InFocus projector is specifically designed for home theater applications.

The projector also provides the following connectors: · · RS-232 for serial control (not included on the IN72) 12 volt DC output (see below) 12 volt DC output HDMI M1-DA/ DVI RS-232 (not on IN72) +12v ground 12 volt DC output The 3.5mm mini-jack trigger provides a 12 volt, 0.25 amp DC output. It provides a constant output while the projector is on. It has numerous uses. For example, if you connect your projection screen to the 12 volt DC output with the cable that came with your screen, 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. 3.5mm plug 12 volt DC output to, for example, screen relay (see screen manufacturer for details) 4 Positioning the projector To determine where to position the projector, consider 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 guidelines: · · Position the projector on a flat surface at a right angle to the screen. The projector must be at least 4.9 feet (1.5m) from the projection screen. For safety reasons, position the projector within 10 feet (3m) of your power source (running extension cables may introduce a trip hazard). To ensure adequate cable access, do not place the projector within 6 inches (.15m) of a wall or other object. If you are installing 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 "Ceiling" on page 26. We recommend using an InFocus authorized ceiling mount. 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. The image offset is 128% for the IN72. This means that if you have an image 10' high, the bottom of the image will be 2.8' above the center of the lens. For the IN74/ IN76/IN78, the image offset is 115%. Projection angle in 16:9 mode 10 ft high image Table 1: Range of distance to the screen for a given screen size for the IN72 Distance to screen Diagonal Screen Size (inches/m) Maximum distance (feet/m) Minimum Distance (feet/m) · 60/1.5 80/2 92/2.3 150/3.8 9.3/2.8 12.3/3.8 14.2/4.3 23.1/7 7.8/2.4 10.4/3.2 12/3.7 19.5/5.9 · Table 2: Distance to the screen for a given screen size for the IN74/IN76/IN78 Distance to screen Diagonal Screen Size (inches/m) Maximum distance (feet/m) Minimum Distance (feet/m) · bottom of image 2.8 ft above center of lens 60/1.5 80/2 92/2.3 150/3.8 8.3/2.5 11.1/3.4 12.8/3.9 20.8/6.3 6.6/2 8.8/2.7 10.1/3.1 16.4/5 NOTE: Visit the Service section of our website at www.infocus.com/calculator for an interactive image size calculator. lens center 5 Choosing the aspect ratio Aspect ratio is the ratio of the image width to image height. HDTV and most DVDs are 16:9, which is the default for this projector. When in 4:3 mode the projector places black bars on both sides of the image. Native mode centers the image and turns off the internal scaler so that any resolution larger than the native projector resolution is cropped on the edges. Letterbox expands the image to fill the screen. What you plan to project will also help you choose between 4:3 and 16:9. For example, 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 and 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 4:3, Native, or Natural Wide 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. Natural Wide stretches a 4:3 image to fill the entire 16:9 screen. The center two-thirds of the image is unchanged; the edges of the image are stretched. 16:9 image input 16:9 aspect ratio 9 9 16:9 image 16 16 4:3 image input 4:3 image on 16:9 screen black bars 4:3 aspect ratio 9 4 letterbox image input black bars 16 16:9 image fills 16:9 screen letterbox aspect ratio 3 black bars 9 4 16 4:3 image input natural wide aspect ratio 4:3 image fills 16:9 screen 3 9 4 16 6 black bars 3 Video connectors The first step for connecting video is determining what type of output connectors your video device has. If there is more than one output, select the one with the highest quality. The best quality ranking, with 1 being the highest, is: For detailed information on supported video formats, see page 35. 1 M1-DA/DVI or HDMI (both are digital inputs) 2 component /SCART RGB video (RCAs) 3 S-video 4 composite video (RCA) If your device has a VGA connector, you can use the M1-DA/DVI connector for a high quality image. Many PC game systems have VGA connectors. component RCA SCART (all 4 connectors) 12 volt DC output HDMI M1-DA/ DVI S-video composite RCA RS-232 (not on IN72) 7 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. Connect the audio from your video device to your stereo system to get sound. 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. A composite video cable is provided with your projector so you can quickly and easily connect a video source to the projector and see the amazing image that is displayed. Once you have determined a more permanent location for your projector, we recommend purchasing higher quality cables in the proper length to get the best image from your particular video equipment. High quality cables optimized for your projector can be purchased from www.infocus.com/store (in select areas) or from your dealer or retailer.
