Basic Operation
Adjustment range by the lens position shift (optical shift)
Perform the lens position shift within the adjustment range.
The focus may change when the lens position is shifted out of the adjustment range. This is because the
movement of the lens is restricted to protect the optical parts. Projection position can be adjusted with the optical
axis shift based on the standard projection position in the range shown in the following gures.
