Please do not remove your sensor if the alert has been present for less than 3 hours.
Sensor Updating occurs when the sensor signals are outside of the expected range.
Please check that the sensor is still securely taped to the skin and not dislodged.
The alert may persist for up to 3 hours but often resolves itself within a shorter period and will either: display the SG value again, request a calibration or advise you to change your sensor. Continue sensing and monitor your pump because the system may recover.
In the event that the updating lasts for more than 3 hours, the recommendation is to replace the sensor to maximise the time in SmartGuard™ feature.
