12-ENGLISH
After moving the lens to the home position according to “Lens calibration” on page 7,
you can use the position of the projected image at that position (i.e., the standard
projection position) as a basis, and use the lens shift adjustment function on the projector
to adjust the position of the projected image within the respective lens shift ranges.
Perform lens shift adjustment within the ranges shown in the following illustrations.
Moving the lens outside of the adjustment ranges may alter the focus. This occurs due
to limitations in lens movement that are intended to protect the optical components.
The following illustrations depict lens shift ranges for floor installations of the projector.
