You can turn on and customize each of these alerts:

Receiver: Go to Menu > Settings > Alerts.

The Falling Fast alert is similar to the Urgent Low Soon alert:
Urgent Low Soon alert: Tells you when your glucose is falling so quickly it'll be at
l
55 mg/dL within 20 minutes.
Urgent Low Soon is tied to a specific sensor reading (55 mg/dL) and time (20
minutes).
Falling Fast alert: Also tells you your glucose is falling quickly, but you set the
l
level that triggers it and it isn't tied to time.
If your glucose is falling fast and is at or below 55 mg/dL, you'll get an Urgent Low
alert, not a Falling Fast alert.
Go to the changing alerts sections of the
50
Alerts chapter for more information.
