Techniques are provided for alerting a person to check a medical device while conserving battery power. The medical device initiates a status alert if a readiness condition of the medical device is no longer being met. The status alert includes notification periods during which an audible sound is emitted alternating with off periods during which substantially no audible sound is emitted. The audible sounds may include certain tones or at least one spoken word. At least one of the duration of successive notification periods or the duration of successive off periods may be varied. In this manner, the medical device may provide audible sound at different times during the day in an attempt to get the attention of a person. In addition, the medical device may sense an activity to determine when to provide the audible sound.
