Abbott FreeStyle Libre 2 User Manual

• If you adjust the phone ringer volume 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.
• Disable your phone’s automatic operating system updates. After
an operating system update, open your App and check your device
settings to make sure it’s working properly.
• Some operating system features may impact your ability to receive
alarms. For example, if you use the iOS Screen Time feature, add
FreeStyle Libre 2 to the list of Always Allowed apps to ensure that you
receive alarms.
