Symbol Explanation
Calibration in Progress
Appears on the glucose trend line and the Event Log during the ~15 minutes while a calibration is in
progress. The icon will turn either red, black or blue when calibration is no longer in progress.
Calibration Incomplete
Appears on the glucose trend line and the Event log when not enough data is collected to complete
the calibration. For example, when the transmitter is removed from over the sensor during the
~15 minute calibration period.
Calibration Cannot be Used
Appears on the glucose trend line and the Event Log when a calibration has been entered that
cannot be used. For example, the value entered is less than 40 mg/dL or more than 400 mg/dL.
In this case, the calibration value is stored as a manual BG entry.
