The alarm* will sound for 1 minute and will repeat every 5 minutes until you acknowledge it by swiping the notification and opening the app**, or long tapping and selecting 'Dismiss'.
The alarm will repeat again after 30 minutes, even if acknowledged, if you enter a new episode where your glucose rises above or falls below a certain threshold.
* Notifications will only be received when alarms are turned on and the sensor is within 33 feet unobstructed of the reading device. You must enable the appropriate settings on your smartphone to receive alarms and alerts, see the FreeStyle Libre 3 User's Manual for more information.
