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.
iPhones are to be configured as follows:
In the phone settings, keep Bluetooth ON
In the phone settings for the App, allow the App to access Bluetooth
In the phone settings for the App under Notifications, keep Allow Critical
Alerts ON
Android Phones are to be configured as follows:
In the phone settings, keep Bluetooth ON
In the phone settings for the App, keep Do Not Disturb Access permission
ON
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 Critical Alerts, Do Not Disturb Permission, and Bluetooth, 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.
