Setting App Alarms
When in range of the App, your Sensor automatically communicates with the App to give you several types of alarms. Work with your health care professional to determine your alarm settings.
How to do it:
Caution
- Disable your phone’s automatic operating system (OS) updates. Prior to updating your phone’s OS or updating the App, you should check the Mobile Device and OS Compatibility Guide to determine if the FreeStyle Libre 2 App is compatible with your OS and your phone. The OS Compatibility Guide is available in the Help Section of the App or on www.FreeStyleLibre.com. You should check the OS Compatibility Guide periodically to make sure that your OS and your phone continue to be compatible with the App.
- In the event that an App or OS update causes your previously compatible phone to become incompatible, you may be notified ahead of time via e-mail or through the App. Make sure that your LibreView account has your current e-mail address to receive important information.
- After an OS update, open your App and check your device settings to make sure it's working properly. Some OS features may impact your ability to receive alarms. For example, if you use an iPhone and the iOS Screen Time feature, add the FreeStyle Libre 2 app to the list of Always Allowed apps to ensure that you receive alarms or if you use an Android Phone do not use the Android Digital Wellbeing app.
- For you to receive alarms, your phone should be within 20 feet of you at all times. The transmission range is 20 feet unobstructed. If you are out of range, you may not receive alarms. If you want to receive the App's optional alarms, make sure these are turned on.
- For iPhone, do not force close the App. The App must be running in the background to receive alarms. If you force close the App you will not receive alarms. Re-open the App to ensure you will receive alarms.
- If you restart your phone, open your App to make sure it’s working properly.
- Glucose alarms you receive do not include your glucose reading so you must scan your Sensor to check your glucose.
- The App will ask for phone permissions which are needed to receive alarms. Allow these permissions when requested.
- Check to make sure that you have the correct phone settings and permissions enabled. If your phone is not configured properly, you will not be able to use the App, so you will not receive alarms or be able to check your glucose. Refer to the User manual to make sure you have the correct settings and permissions enabled on your phone.
- If your phone is not configured correctly, the App will be in "Alarms Unavailable" state and you will not be able to check your glucose or receive any alarms, including the Urgent Low Glucose Alarm.
- To turn on Bluetooth, Critical Alerts, Do Not Disturb access permission, Bluetooth access, and Nearby Devices permission, follow the instructions in the App.
- For Android Users, you may need to add the FreeStyle Libre 2 app to the list of apps that will not be restricted or put to sleep.
- If you adjust the phone ringer volume (iPhone) or Media volume (Android Phone) to silent or use the phone Do Not Disturb setting, keep ‘Override Do Not Disturb’ setting in the App ON for Low Glucose, High Glucose, and Signal Loss Alarms to ensure you receive audible alarms.
- You should disconnect headphones or speakers from your phone when you are not using them as you may not hear audio for alarms. If using headphones, keep them in your ears.
- If you are using peripheral devices connected to your phone, such as wireless headphones or a smartwatch, you may receive alarms on only one device or peripheral, not all.
- Keep your phone well charged and turned on.
