What Is an Alarm?
While there are a variety of Alerts , there is just one Alarm , the Urgent Low Alarm (Alarm) is
set at 55 mg/dL. The Alarm will repeat every 5 minutes until you clear the Alarm (see Chapter
12 on how to customize the sounds). If you clear the Alarm and your sensor glucose readings
do not go over 55 mg/dL in the next 30 minutes, you get another Alarm.
Unlike Alerts , the Urgent Low Alarm setting can't be changed or turned off . Think of it as a
safety net: your glucose level is dangerously low—pay attention now!
What Are Alerts?
An Alert is a message telling you your glucose trend levels need attention.
Low/High glucose Alerts tell you when your sensor glucose readings are outside your target
glucose ranges. Think of them as an FYI: You need to know what's happening, Rising/Falling
Alerts tell you your glucose levels are changing quickly. Their default settings are Off (see
Chapter 12 on how to turn them on).
Alerts message you with vibrations (vibrations not available on all smart devices), visual
prompts, sounds, or a combination of all three.
Unlike the Alarm, you can customize your different Alert's target range (Chapter 12).
During your initial set up, you establish your low and high 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 prompts,
how you are notified, and in some cases, how often you get notified. The following are
the defaults.
Default Alerts
Low/High Alerts
Your Low/High 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 high/low Alert levels.
a. No Alerts.
3. Yellow: Glucose levels are above your high threshold.
a. Default setting of 200 mg/dL.
