Default Alerts
Low/High Glucose Alerts
When making treatment decisions using your Dexcom G5 Mobile CGM System, it’s best to
keep your Alerts turned on.
Your Low/High Glucose Alerts have the same color-coding as your trend graph:
Red
• Glucose levels are below your low threshold.
• Default setting of 80 mg/dL. You may have changed this during setup.
Gray
• Glucose levels are within your Low/High Glucose Alert levels.
• No Alerts.
Yellow
• Glucose levels are above your high threshold.
• Default setting of 200 mg/dL. You may have changed this during setup.
Rise Rate/Fall Rate Alerts
Rise Rate and Fall Rate Alerts warn you when your glucose levels are changing rapidly, either
up or down, and look similar to the rate of change arrows.
Rise Rate and Fall Rate are off by default.
Signal Loss Alert
Signal Loss tells you when you and the transmitter are too far from your display device
or something is blocking your transmitter signal, causing you not to get sensor glucose
readings.
The Signal Loss Alert is on by default.
Now you have the basics for the G5 Mobile Alarm/Alerts. Next, you will learn about each
Alarm/Alert in more detail.
