Entering your Transmitter SN into your Dexcom receiver

Remember, your Dexcom G6 Continuous Glucose Monitoring (CGM) transmitter is reusable for about 3 months, while the diabetes sensor has a 10-day wear cycle. When it is time to use a new transmitter, you must also start a new sensor session.

The Dexcom transmitter serial number (SN) is a 4-digit code (a series of numbers and/or letters) that’s required to pair your Dexcom CGM System to your display device^*, in this case, your receiver.^*

The Dexcom G6 transmitter serial number 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

To set up your receiver, turn it on by pressing the power button for 3–5 seconds and then follow onscreen instructions to remove the sensor and transmitter.

Automatically start new Dexcom sensor and transmitter When your transmitter expires, you'll be prompted to pair a new transmitter. Follow these steps: On your receiver,* enter the new sensor code and new transmitter SN Insert new sensor and attach new transmitter Start the 2-hour sensor warmup
Manually start new Dexcom sensor and transmitter To stop a transmitter early, at your convenience, follow these steps: On your receiver,* go to Menu > Information > Transmitter > Pair New Transmitter Follow the on-screen instructions to remove your sensor – enter the new transmitter SN and sensor code Insert new sensor and attach new transmitter Start the 2-hour sensor warmup

If you do not see the Dexcom G6 transmitter serial number 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.

For more information, see the Dexcom G6 User Guide.

* The optional receiver may be purchased through the Dexcom Store.
