Chapter 3 Basic Operations — Projecting

Lens shift range
The projector can adjust the position of the projected image within the lens shift range for each projection lens
based on the position of the projected image in the home position (standard projection position).
Perform the lens shift adjustment within the range indicated in the following illustration. Note that moving the lens
outside the adjustment range may change the focus. This is because the shift of the lens is restricted to protect
the optical parts.
Following illustration indicates the lens shift range when the projector is installed on desk/oor.
