The FreeStyle Libre 2 system has three optional alarms:
• Low Glucose Alarm - an alarm will notify your patients when your glucose falls below a level you set
• High Glucose Alarm - an alarm will notify your patients when your glucose rises above a level you set
• Signal Loss Alarm - an alarm will notify your patients when the glucose alarms they have set are not available because their Sensor has lost communication with the Reader or app for 20 minutes
