Entering your Transmitter SN into your Dexcom receiver
The transmitter SN is a series of numbers and/or letters that can be found in the following locations:
- On the transmitter box label - the transmitter SN number is the same as the SN number on the box
- On the bottom of the transmitter - the transmitter SN number is the same as the SN number on the bottom of the transmitter
You can only set your transmitter SN when you are not in a sensor session. During a sensor session, Transmitter SN will not be an option on the settings menu.
If you do not see the Transmitter SN 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.
