Shifting the projection lens vertically
The vertical lens shift control provides flexibility for installing your projector. It allows the projector
to be positioned slightly above or below the top level of the projected images.
The lens shift (offset) is expressed as a percentage of the projected image height. It is measured
as an offset from the projected image's vertical center. Use the lever to shift the projection lens
upwards or downwards within the allowable range depending on your desired image position.
To shift the lens:
1. Press down lightly on the lens adjustment panel cover switch (indicated by a dot) to click it
open.
2. Lift the lens adjustment panel cover up.
3. Turn the lens shift ring to adjust the projected image position.
4. When done, press down and click close the lens adjustment panel cover.
• When the screen position is fixed
• When the projector position is fixed
• Do not over-tighten the lever.
• Lens shift adjustment does not result in a degraded picture quality. In the unlikely event that the image
distortion is produced, see
"Adjusting the projected image" for details.
