What does the Transmitter Not Found alert mean?

If your transmitter didn’t pair with your display device and you are seeing a Transmitter Not Found alert, please try the below solutions:
  • Make sure the transmitter is snapped into a sensor and is flush with the sensor pod. You should hear a click when snapping your transmitter into the sensor, and the transmitter should be sitting flush in the sensor pod.
  • Transmitter tab and slot
  • Make sure the transmitter SN in Settings matches the transmitter SN on the transmitter box.
  • Use your meter to make treatment decisions as you will not get Dexcom G6 readings, alarm or alerts until fixed.
  • App: For more information, tap Help.
