Positioning the projector
Table 1: (IN3102 & IN3104)
Range of distance to the screen for a given screen size
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 general 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.
•
Position the projector within 10 feet (3m) of your power source and
within 6 feet (1.8m) of your video device (unless you purchase
extension cables). 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 mount” on page 30. We
recommend using an InFocus authorized ceiling mount.

Distance to screen
The image exits the projector at a given angle. IN3102/IN3104 image
offset is 115% ; IN3106 image offset is 112.4%. This means that if you
have an image 10’ high, the bottom of the image will be 1.5' (IN3102/
IN3104) and 1.24' (IN3106) above the center of the lens.
