The SB date is the Ship By Date. Have you read these topics below? Based on the comments in these threads I think it’s highly unlikely the transmitter still works. According to @Michel a Dexcom agent admitted that 80-90% of transmitters fail when you start it 12 months after the manufacture date. If possible, return it to the seller.

> Sensors, yes, but I can’t get a stockpile of transmitters, so depending on where I am with those, I could be out of my Dexcom supplies fairly quickly. Personally, I could afford to buy a transmitter and would. But the statistics for American households are that almost half can’t cover an unexpected $400 emergency, so I don’t think that’s true generally.
