What is the Signal Loss alert and what do I do when I get the alert?

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. For best practices on how to minimize signal loss, click here. Additionally, your phone settings can prevent the Dexcom G6 app from working. To learn more about phone settings that can help your app to work as expected, click here.
To fix this:
  • Keep your transmitter and display device within 20 feet of each other.
Dexcom G6 app:
  • Bring the running G6 app to the foreground.
  • Do not swipe close your app, it is intended to run at all times
  • If this doesn't resolve your issue, try turning Bluetooth off and then on and wait 10 minutes.
  • If unsuccessful, restart your smart device, unlock the main display and reopen the Dexcom G6 app and wait 10 minutes.
  • Make sure your phone is charging or charged. Low power mode on smartphones may turn off Bluetooth connections.
Dexcom receiver:
  • Verify the correct transmitter SN and activation date – this information is in the receiver under Menu> Settings> Transmitter Info.
