What it may mean
The sensor tip may not be under your skin.
What you can do
Try to start your sensor again. If you see “Check Sensor” again on the screen, your sensor was not applied properly. Remove this sensor and apply and start a new sensor.
We apologize for the inconvenience. You are likely eligible for a replacement sensor.
Would you like to request a new sensor now?
To speed things up, please have your sensor’s serial number ready. You can find the serial number of your last three sensors in the “About” section of the app or "System Info" in the reader.
If you still need help, we are available:
7 days a week 8 AM to 8 PM Eastern Time, excluding holidays.
