Receiving an error message related to your transmitter lifespan
The transmitter battery lasts for 3 months after initial activation. Starting 3 weeks before the end of it's battery life, the warnings count down the transmitter battery life until it only has 10 days - one sensor session - left.
If the transmitter battery has less than 10 days remaining, you won't be able to start a new session and will see "Pair New transmitter" instead. Dexcom recommends that you have your next transmitter in hand within 3 months of starting your previous transmitter.
