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. IN122ST
and IN124ST must be at least 24” (0.6m) from the projection screen, and
IN126ST must be at least 32” (0.8m) 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 desired 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 IN122ST/IN124ST is 110% +/-3%. This means that if you
have an image 60 inches (1.52 meters) tall from a table-mounted projector,
the bottom of the image will be 6 inches (15.2 cm) above the centerline of the
lens. The image offset for IN126ST is 113% +/-3%. This means that if you
have an image 60 inches (1.52 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.
