Entering your Transmitter ID into your Dexcom G5 Mobile Receiver

The transmitter ID is a series of numbers and/or letters that can be found in the following locations:

  • On the transmitter box label – the transmitter ID number is the same as the SN number on the box
  • On the bottom of the transmitter - the transmitter ID number is the same as the SN number on the bottom of the transmitter

You can only set your transmitter ID when you are not in a sensor session. During a sensor session, “Transmitter ID” will not be an option on the settings menu. If you don’t see the “Transmitter ID” in the settings menu, select STOP SENSOR first.

NOTE: Selecting STOP SENSOR will end a sensor session you may have with a current working transmitter.
