Sensor Glucose Alarm and Alerts
214
Alerts message you with vibrations (vibrations not available on all smart
devices), visual notifications, sounds, or a combination of all three.
Unlike the Alarm, you can customize your different Alert’s target range (see
Chapter 12).
During your initial setup, you establish your Low/High Glucose Alert levels. As
mentioned before, this chapter is a review of the Alarm and Alerts,
recommended smart device settings, and the receiver’s default Alert settings.
Chapter 12 will show you how to change their settings: customize glucose
levels notifications, how you are notified, and in some cases, how often you
get notified. The following are the defaults.
Default Alerts
Low/High Glucose Alerts
Your Low/High Glucose Alerts have the same color-coding as your trend
graph screen:
1. Red: Glucose levels are below your low threshold.
a. Default setting of 80 mg/dL.
2. Gray: Glucose levels are within your Low/High Glucose Alert levels.
a. No Alerts.
3. Yellow: Glucose levels are above your high threshold.
a. Default setting of 200 mg/dL.
Rise Rate/Fall Rate/Repeat Alerts
Rise Rate and Fall Rate Alerts warn you when your glucose levels are
changing rapidly, either down or up, and look similar to the rate of change
arrows. Repeat Alerts let you know if your sensor glucose readings continue
to be above or below your Alert levels.
