Paragraph Number

135

To calibrate the surgical device 200c, a user may press the zero-out switch 256 (for example, a button) (i.e., activate a zeroing switch). Pressing the zero-out switch 256 may send a zero-out input signal to a calibration circuit 340 of the electronic circuit 300/400. In response to the zero-out input signal, the calibration circuit 340 may determine a horizontal plane 614 and/or reference axis 130. In certain embodiments, re-orienting the surgical device 200c for the calibration mode may not be needed.
