button.
f [PROGRESS] is displayed in the [HOME POSITION] screen, and the lens returns to the home position.
Note
f 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.
f You can also display the [HOME POSITION] screen by pressing the <LENS> button on the control panel or the <SHIFT> button on the
remote control for at least three seconds.
Adjustment range by the lens position shift (optical axis 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
respective range.
