x 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 GT20ZL:
Up: 0.5 V (V: height of projected image)
Down: 0.5 V
Right:
0.32 H (H: width of projected image)
Left: 0.32 H
NOTE: Lens shift is not available on the GT10RLB rear lens. The GT10RLB should be used only for “zero degree/no-offset” applications.
NOTE: If 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.
2. Installation
WARNING
* Installing the projector on the ceiling must be done by a qualified tech-
nician.
• 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 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 pro-
jector 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.
