A friend has the question, stated below. I have not encountered this.
“My dex receiver beeps loudly and says initializing on the screen, stays blank for a minute or two, then 2 more beeps and back to regular graph screen, it happening more regularly the last few days, is this a fault or a normal thing for it to do?”
After I started using the “skin” it happens to me alot when I put my receiver in my pants pocket. I think it is caused by static electricity. When I asked tech support about it, they told me that it would not harm the receiver and it would not affect my data.
It’s just the receiver re-booting, often due to static. I had the same problem, and it was happening multiple times a day and Dexcom replaced my receiver. It will happen more in the winter when the air is dry and if you keep the receiver in your pocket. Putting it in a case of some type will help a lot - I have one of the silicon covers - it also keeps dust from getting under the screen. If it’s happening very fequently, give Dex a call.
