Lens Shift Adjustable Range
The top right 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 GT12ZLB/GT20ZL/GT48ZLB lenses:
*Values for 16:9 screens in parentheses.
Up:
0.5H
(0.67H)
H
=Height of image (take care to use appropriate value for 4:3 or 16:9 screens)
Down:
0.5H
(0.67H)
W
=Width of image
Right: 0.32W
Left: 0.32W
Note: Lens shift is not available on GT06RLB & GT10RLB rear lenses, which should only be used for “zero degree/no-offset” applications.
Note: If the lens is shifted in two directions combined, maximum range in either direction cannot be obtained due to rounded off area of
lens. (example: shift up and right) See top right diagram.
Note: The diagram below shows a 4:3 image as an example.
Warning:
•
Installing the projector on the ceiling must be done by a qualified
technician.
•
Tilting the front of the projector up or down by more than 45° from
level could reduce lamp life by up to 20%.
•
Only use the 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 the projector so
heat can dissipate. Do not cover any vents on the projector.
