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.
