What Do I Do if I’m Not Hearing my Alarms on my Smart Device?

If you’re using a Dexcom G5® Mobile CGM System and you noticed that you missed a notification but didn’t get a Signal Loss Alert, double-check your smart device* settings and the sound settings in the app.

Your alarm and important alerts can notify you with sound even when:

  • The device volume is low.
  • The device is on Mute, Vibrate, or Do Not Disturb.

You always get a visual notification, but you may not hear sound on your first notification. Unless you clear an alarm or alert, it repeats at half volume after 5 minutes, and at full volume every 5 minutes after that.

Important: If you have chosen Vibrate-only as your sound setting for an alert, that alert will never make a sound. The G5 app cannot override most wired and Bluetooth headphones or other accessory devices. Do not assume you will hear alerts when accessories are connected to your smart device.

As always, make sure the smart device and transmitter are within 20 feet of each other, with nothing blocking the transmitter’s signal.
