Lens Shift Adjustable Range
The diagram shows the location of the image position in the lens. The lens can be shifted within the shaded area as shown
using the normal projection position as a starting point.
Maximum Possible Range
(for zoom lenses only: fixed lens cannot be shifted):
Up: 0.5 H where H: height of projected image
Down: 0.16 H
Right: 0.1 W
where W: width of projected image
Left: 0.1 W
NOTE: If lens is shifted in two directions combined, maximum range in both directions cannot be obtained due to circular shape of lens.
(example: shift up and right - see dotted box in diagram below.)
NOTE: zoom lenses only: fixed lenses cannot be shifted without losing the corners of the image
WARNING
* Installing the projector on the ceiling must be done by a qualified
technician.
• Tilting the projector from side to side by more than 12° from level
will reduce lamp life (see page iv).
• Only use your projector on a solid, level surface. If the projector
falls, you could be injured and the projector severely damaged.
• Do not use the projector where temperatures vary greatly. The
projector must be used at temperatures between 32°F (0°C) and
95°F (35°C).
• Do not expose the projector to moisture, dust, or smoke. This will
reduce the quality of the image.
• Ensure that you have adequate ventilation around your projector
so heat can dissipate. Do not cover the vents on the projector.
