bottom discrimination or partial bottom zoom is turned

Relationship between Zoom Range/Zoom Position and Depth Range/Shift
Changing the depth range or shift position does not change the zoom range or zoom position being
previously set. If you change the zoom range or zoom position using the Zoom Range key or Zoom
Position key, this change is implemented using the currently selected depth range or shift position as
the reference. If, in this case, the zoom range or zoom position is out of the screen, zooming is
executed using the top of the normal screen as the zoom position.
