How do I start my Dexcom G6 sensor?

When you start a new Dexcom sensor, you must enter a code into your display device to use Dexcom G6 without fingerstick calibrations. * Please make sure to follow each onscreen prompt step by step when starting a new sensor. Each sensor has its own code printed on the back of the adhesive patch. Do not use a code from a different sensor or make up a code. If you have lost the sensor code, you may calibrate Dexcom G6 using fingersticks. Learn more about what to do if you lose your sensor code here.
*If your glucose alerts and readings from the Dexcom G6 do not match symptoms or expectations, use a blood glucose meter to make diabetes treatment decisions.
