For information on how to pair a new transmitter, please visit this page.

Dexcom G6 transmitters are under a limited warranty for the first 90 days from activation provided that activation was within 5 months of the shipping date. You can find your transmitter activated date in the settings screen in your display device. If using a receiver device, go to Menu > Settings > Transmitter > Transmitter Info. If using the app, go to Settings > Transmitter. This will allow you to view the activated date. See image below for reference.

Please reference our user guide for specific warranty information.

If your transmitter is more than 90 days old and not working, you must use a new transmitter. If your transmitter is less than 90 days from activation, contact Global Technical Support for troubleshooting by requesting a call back or by calling 1-844-607-8398.
