A blood pressure monitor has a noninvasive continuous blood pressure measurement mode and a non-continuous blood pressure measurement mode. At the time of a first sale, the noninvasive continuous blood pressure measurement mode is disabled. Thus, the blood pressure monitor operates only in the non-continuous measurement mode. At a later time, a sensor is sold to generate a sensor signal for noninvasive continuous blood pressure measurements, thereby enabling the continuous measurement mode of the blood pressure monitor.
