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 general guidelines:
• Position the projector on a flat
surface at a right angle to the screen. The IN112
and IN114 must be at least 45.3” (1.2m) from the projection screen, the
IN114ST must be at least 31” (.8m) from the projection screen, and the IN116
must be at least 55.4” (1.4m) from the projection screen.
• If you are installing the projector on the ceiling, we strongly recommend using
InFocus approved ceiling mounts for proper fitting, ventilation and
installation. Refer to the installation guide that comes with the InFocus Ceiling
Mount Kit (p/n PRJ-MNT-UNIV) for more information. The warranty does
not cover any damage caused by use of non-approved ceiling mount kits or by
installing in an improper location. To turn the image upside down, see “Ceiling
mount” on page 27. We recommend using an InFocus authorized ceiling
mount.
• Position the projector the de
sired distance from the screen. The distance from
the lens of the projector to the screen and the video format determine the size
of the projected image.
• The image offset for the IN112/IN114/IN1
14ST is
115% +/-5%. This means
that if you have an image 60 inches (1.5 meters) tall from a table-mounted
projector, the bottom of the image will be 9 inches (22.9 cm) above the
centerline of the lens. The image offset for the IN116 is 113% +/-5%. This
means that if you have an image 60 inches (1.5 meters) tall from a table-
mounted projector, the bottom of the image will be 7.8 inches (19.8 cm) above
the centerline of the lens.
