8-ENGLISH
After moving the lens to the home position according to “Lens calibration” on page 6,
you can use the lens shift adjustment function on the projector to adjust the position of
the projected image within the respective lens shift ranges based on the optical screen
center position (standard projection position). The optical screen center position is the
screen position using the optical center of the projector as the base.
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.
