A “Sensor Error” message appears when the sensor is unable to provide a glucose reading. Scan again after the duration specified in the message.
Note: If you receive this error during your first 12 hours of wearing a sensor, it may mean that your body is still adjusting to the sensor. Use a blood glucose meter to check your glucose while you wait. You do not need to remove your sensor1.
If the “Sensor Error” message continues to appear please complete the online sensor support request form or contact our Customer Care Team at 855-632-8658.
