Estimates of how well the adjustable High Glucose Alert performs are presented in the
table below. For example, if you set the High Glucose Alert to 200 mg/dL, the Seven
System will alert when your glucose levels rise above 200 mg/dL 79% of the time (True
Alert). Additionally, 8% of the time when the alert sounds, the glucose level will actually
be below 200 mg/dL (False Alert).
