What it may mean
Check that you are using the app or reader that is compatible with your sensor. You may need to download a different app if your sensor is not compatible.
What you can do
If you are using an app, please also check the Apple App Store or Google Play to ensure you have the most recent version. If necessary, update to the latest version. Please review one of our Sensor, Device and App Compatibility Guides to determine which sensors are compatible with your app or reader, or contact our Customer Care Team at 1-800-461-8481.
We apologize for the inconvenience. You are likely eligible for a replacement sensor.
