[PROGRESS] is displayed in the menu screen, and the lens
returns to the home position.
Attention

The home position of the lens is the lens position when the lens is being replaced or when the projector is being stored, and it is not the
optical center of the screen.
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.
