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 wheel to shift the projection lens upwards or
downwards within the allowable range depending on your desired image position.
To use the lens shift wheel:
1. Slide off the lens compartment cover (see item 6 on page 8) over the lens shift wheel.
2. Release the wheel by turning it counterclockwise.
3. Move the wheel to adjust the projected image position.
4. Lock the wheel by turning it clockwise.
• When the screen position is fixed
• When the projector position is fixed
• Do not over-tighten the wheel.
• 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.
