* True Alert Rate is the % of time when the blood glucose level was at or below the alert
setting and the alert sounded.
** False Alert Rate is the % of time when the device alarmed but the blood glucose level
was above the alert setting.
*** Missed Alert Rate is the % of time when the device failed to alarm when the blood
glucose level was at or below the alert setting.

The High Glucose Alert
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 G4-Global Receiver should alert you 81% of the time within
5 minutes when your blood glucose levels rise above 200 mg/dL (True Alert).
Additionally, 7% of the time when the alert sounds, the glucose level may
actually be below 200 mg/dL (False Alert) at this time.
