ENGLISH-11
After moving the lens to the home position according to “Lens calibration” on page 8, 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.

Note
z
The home position of the projector a point of origin position for the lens shift (i.e., vertical and
horizontal positions of the lens) based on the results of lens calibration. It is not the optical
center position of the screen.
