Lens Shift Function - Canon WUX500ST Quick Start Manual

Lens Shift Function

You can reposition the image in all directions by turning the lens shift dials on the
side of the projector, which moves the lens up, down, left, or right. For instructions,
refer to "Adjusting the Image Position" (P46).
■ Amount of Lens Shift
The amount of lens shift is indicated as a percentage relative to the image height
and width. The lens shift ranges for the projector are as follows.
A (Amount of shift up)
B (Amount of horizontal shift)
The lens can be shifted up and to the left or right. Performance using lens shift is
ensured within the recommended range described below. Using lens shift outside
of this range may cause problems such as peripheral dimness or lower resolution.
In this case, adjust lens shift to within the recommended range.
