How to scan your sensor
After applying your FreeStyle Libre 2 Plus sensor, you will need to activate it with FreeStyle Libre 2 reader.

If you start your FreeStyle Libre 2 sensor with your FreeStyle Libre 2 reader you will not receive real-time glucose readings, even if you use the updated FreeStyle LibreLink app 2,3 as your second device. You will need to scan to get your glucose reading on both devices. Glucose alarms are only received on the device used to start the sensor.

1. Once you activate a sensor with a reader, you can receive alarms from the reader only. To use the same sensor with your compatible smartphone, start your sensor with the reader then scan it with FreeStyle LibreLink app. If you are using two devices with the same Sensor, be sure to scan frequently with both devices.
2. The FreeStyle LibreLink app is only compatible with certain mobile devices and operating systems. Please check the website for more information about device compatibility before using the app. Use of FreeStyle LibreLink may require registration with LibreView.
3. Glucose readings are automatically displayed in the app only when the smartphone and sensor are connected and in range.
