    when the controller determines that the position of the removal switch is in an open position, continuously determining, at the controller, an orientation of the head unit based on an output signal from an accelerometer coupled to the head unit;

    determining, at the controller, whether the orientation of the head unit is within a predetermined range of orientations; and
