Installation

Shifting the projection lens vertically (W1070+ only)

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 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.

• 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.
