The controller (5) includes an interface (53), and is further configured or programmed to include a restriction unit (21) to restrict a control operation for the limited function, and a restriction cancellation unit (22) to cancel the restriction effected by the restriction unit (21) to permit the control operation for the limited function if a predetermined keycode is inputted from the interface (53) or is registered in the controller (5).",
