3.4 Lens shift

General
Use the Remote control or the keypad on the Projector to adjust the lens shift mechanism.
The lenses can be shifted vertically and horizontally to facilitate precise image positioning in single and
multiple projector systems. The projector allows for horizontal and vertical shift in both directions. Always
place the projector perpendicular to the screen, and use the lens shift to align the picture.
If not possible to align the projector perpendicular to the screen, due to environmemt of other, see chapter
"Warp – 4 Corners adjustment", page 95
When EN 68 lens is installed in the projector, there are some limitations in the lens shift range, in
order to avoid damage to the lens.
This limitation will be identified as an reduction in the output light from the projector when the shift
position exceeds the defined range. The output light will then be reduced to 20% of max.
