An audible signal generator incorporated into a total station to audibly indicate to the user the rotational orientation of the total station, and a method for using the audible indication to perform the tilt sensor calibration. In one embodiment, the present invention indicates to the user of the total station when the tilt sensor has been calibrated with the total station in a first rotational orientation. This embodiment then audibly indicates to the user when the rotational alidade portion of the total station has been rotated to a second rotational orientation. This embodiment then audibly indicates to the user when the tilt sensor has been calibrated with the total station in the second rotational orientation.
