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. You can use the lever to shift the projection lens upwards or downwards within the allowable range depending on your desired image position.
To use the lens shift lever:
1.Release the lever by turning it counterclockwise.
2.Move the lever to adjust the projected image position.
3.Lock the lever by turning it clockwise.
