What’s the difference between the suspend before low, alert before low, suspend on low and alert on low?

The low glucose features allow you to set your pump to alert, to suspend insulin, or alert and suspend insulin if you are either approaching your low Sensor Glucose limit, or you have reached your low Sensor Glucose limit.

• Suspend before low: Your pump temporarily stops delivering insulin if it is predicted that your Sensor Glucose reading will be approaching the low limit within 30 minutes. Turning on suspend before low, automatically turns on alert on low.
• Alert before low: Your system alerts you any time it is predicted that your Sensor Glucose reading will reach the low limit within 30 minutes. The alert before low can be used whether suspend before low is turned off or on.
• Suspend on low: Your pump temporarily stops delivering insulin when your sensor glucose value falls to or below the pre-set low limit. Turning on suspend on low, automatically turns on alert on low.
• Alert on low: Your system alerts you when your Sensor Glucose reading reaches or falls below your low limit. This is not an optional alert.
