This alert tells you when you’re not getting Dexcom G6 readings. Your display device may be too far from your transmitter or there may be something, such as a wall or water, between your transmitter and your display device.

To fix this:

  • Keep your transmitter and display device within 20 feet of each other. Wait 30 minutes.
  • Never close the Dexcom G6 app. The app is intended to run at all times.

 Dexcom G6 app:

  • If that doesn't work, turn Bluetooth off and on. Wait 10 minutes.
  • If that doesn't work, restart the smart device and reopen the Dexcom G6 app.
  • Close background apps.
  • Make sure your phone is charging/charged. Low power mode on smartphones will turn off Bluetooth.

 Dexcom receiver:

  • Verify correct transmitter ID and activation date--this information is in the receiver under Menu> Settings> Transmitter Info.

 

During signal loss, use your meter to check your glucose levels and make any treatment decisions.

You choose how long to wait before you get the alert (20 to 200 minutes, or more) if using the app. When the display device and transmitter connect after a signal loss or similar issue, up to 3 hours of missed Dexcom G6 readings can fill in on the graph.

Apple: Unlike other alerts, the Signal Loss alert can’t make a sound or vibrate if your smart device is silenced or in Do Not Disturb mode.

 

What you hear, feel, and see:

  • Initial alert: Vibrates once.
  • Until confirmed: Vibrates and beeps once every 5 minutes.
  • All other system alerts also vibrate and beep once.
