Low and High
Adjust your Low and High Glucose Alert levels (mg/dL) along with turning on
and setting the time for the Repeat prompt.
Rise and Fall Rates
Your trend screen provides visual cues letting you know your sensor glucose
readings are falling or rising rapidly.
Constantly looking at your screen may not be practical. You can customize
your Rise and Fall Rate Alerts with vibrations or beeps letting you know when
your glucose is rising or falling (2 mg/dL/min or 30 mg/dL up or down in 15
minutes) or rising or falling rapidly (3 or more mg/dL/min or 45 mg/dL or more
up or down in 15 minutes).
Off
The default setting is
for Repeat, Rise Rate, and Fall Rate.
It's important that you discuss your Alert settings with your healthcare
professional.

minutes.
Follow these same steps for turning on the Rise/Fall Rate Alerts and adjusting
your Low Alerts.
