FDA and Dexcom have apparently announced a recall of CGM receivers. This is NOT the CGM device you attach to yourself (sensor, transmitter, combo), just the small handheld phone like receiver. The recall affects the G6, G7, ONE, and ONE+ receivers. See the article on CNET at: https://www.cnet.com/health/medical/these-continuous-glucose-monitors-have-been-recalled-due-to-faulty-speakers-what-you-need-to-do-to-stay-safe/ or at the FDA site: Continuous Glucose Monitor Receiver Recall: Dexcom, Inc. Removes Certain Dexcom G6, G7, ONE, and ONE+ Receivers Due to Speaker Malfunction That May Cause Missed Alerts for Dangerous Blood Sugar Levels | FDA. There’s a link part way down in the CNET article that leads to the FDA site which lists the device UDI/Model # as well as Lot/Sn. Even if you don’t use your’s its worth checking as it may serve as your emergency back-up.
FYI: The recall may be confusing to some of us (like my simple mind). My receiver has one of the indicated reference number (STK-AT-012) and Part Numbers (MT26403-0), but my serial number, according to the Dexcom website, is NOT part of the recall. If you question whether your’s is part of the recall, you can check it at Check Dexcom Receiver | Dexcom. If you have the original box, your number should be located on a label similar to the pic below, with your serial number to the right of a box with “SN” with a box around it. Alternately, you can look at a label on the back of your receiver for a similar SN number (the website has a picture of where its supposed to be located). On the website, enter your SN number twice (2nd time for confirmation for us fat fingered types) and then you’ll get a response whether your receiver is included. Please, don’t enter the number in the picture, (it’s mine) enter your own 
off your box or receiver.
Might be nice if anyone with a recalled receiver would post what Dexcom says to do with it and how to obtain a new one.
Just curious, does anyone use these? I remember getting one way back in the day, but with the phone app and the link to the Tslim, I don’t even think I can hook it up (I recall that there may be only two devices you can pair to). This is a slight hijack of this thread, so @TomH apologies …
Just wondering …
@bostrav59 I received one with my initial order of sensors. It was probably included by my Endo because it was an initial order, but I didn’t see it because of e-script direct to the pharmacy. I take it with me as a backup, but use my iPhone and apps for Dexcom and DIY Trio otherwise. I don’t I’ve ever charged it up or used it to date and still have it in the original box with docs, etc.!
My brother uses one still, because it takes the “medical device” Bluetooth slot. My pump takes that slot for me, and you can’t connect two “medical devices” (just a medical device and phone), so I haven’t used it in years.
