1. A method, comprising:

  • positioning at least a portion of an electrochemical sensor in fluid contact with interstitial fluid under a skin layer;

    generating one or more signals with the electrochemical sensor corresponding to a monitored analyte level in the interstitial fluid;

    communicating with sensor electronics sensor data associated with the generated one or more signals from the electrochemical sensor to a receiver unit;

    determining, using a processor of the receiver unit, a rate of change of the monitored analyte level based on the sensor data received from the sensor electronics;

    determining, using the processor, whether calibration is appropriate based on the determined rate of change and a characteristic of the electrochemical sensor;

    displaying, on a display of the receiver unit, information corresponding to the monitored analyte level after determining whether calibration is appropriate based on the determined rate of change and the characteristic of the electrochemical sensor; and

    disabling the display from displaying the information corresponding to the monitored analyte level when the display has not been activated for a predetermined period of time, wherein during the time when the display is disabled, receiving the sensor data from the sensor electronics and processing the sensor data by a processing unit of the receiver unit.
