Adjusting Projected Image Position Using Lens Shift

The Lens Shift feature provides a lens shift function that can be used to adjust the position of the projected
image either horizontally or vertically within the range detailed below.
Shift is a unique system that provides lens shift while maintaining a much higher ANSI contrast ratio than
traditional lens shift systems.
Note:
Do not rotate lens shift knob further under click sound and lightly press the knob to rotate back.
