Setting the Glucose Alert Limits
Device: 523/723 (Revel), 522/722, Guardian
Did You Know
The HIGH Sensor Glucose (SG) and LOW SG alerts notify you when your glucose reaches or goes above or below your programmed glucose limits. For example, if your LOW SG alert is set at 70 mg/dL, you will receive an alert every time your glucose reaches or goes below 70.
Important
Your glucose limits are not the same as your target glucose ranges. Work with your healthcare provider to determine your glucose alert limits.

Setting the Rate of Change Alerts
Device: 523/723 (Revel), Guardian
Did You Know
Rate of change alerts notify you that your glucose levels are rising or falling at a certain rate. The RISE RATE alert can be helpful if you are prone to forgetting to take insulin or miscalculate a dose since glucose levels tend to spike significantly at these times. Likewise, the FALL RATE alert can be helpful in protecting you when you give yourself too much insulin or do not eat enough food.
| Allowed Range | Default Setting | Increments | |
|---|---|---|---|
| 523/723 (Revel) | 1.1–5.0 mg/dL/min (0.065 0.275 mmol/L/min) | Off | 0.1 mg/dL/min (0.005 mmol/L/min) |
| Guardian | 1.1–5.0 mg/dL/min (0.061 to 0.277 mmol/L/min) | Off | 0.1 mg/dL/min (0.005 mmol/L/min) |
Make sure the EDIT SETTINGS screen is open.

You will be asked first to set a fall rate of 1.1 to 5.0 mg/dL/min, or select to turn it Off. After your fall rate is selected, you will then be asked to set your rise rate. You may set a rise rate of 1.1 to 5.0 mg/dL/min, or turn it Off. It's often best to wait until you have adjusted to CGM to set these alerts.
