How do I turn off G7 CGM alerts that I don’t need?

You can turn off most alerts in their settings. The alerts you can’t turn off in their settings – Urgent Low and technical alerts (like Sensor Fail) – can be set to vibrate using Quiet Modes in the app or Alert Sounds on the receiver.

This applies to both Dexcom G7 and Dexcom G7 15 Day CGM Systems.
