What happens to the Sensor after the 14-day wear period?

After 14 days of wear, the reader notifies the user that the Sensor has ended. The Sensor automatically stops collecting glucose data and should be removed. The reader displays the number of days before the sensor ends. Three days before the Sensor ends, it tells users with the first scan of each day. In the final 8 hours, it tells users with each scan that the Sensor should be replaced with a new Sensor.
