Bethany was out of range for 2 hours at school on Monday (it came back on its own). Called CS and he told me that it wasn't normal for the cgm to be out of range for that amount of time and it could mean the transmitter is going. He said to press the reset button after 20 min if this happens again. Well it did today and the reset button worked but I called CS today and they told me that it's normal for the monitor to go out of range sometimes and that pressing the reset button will fix the problem. I don't know about anyone else but if this happens consistently, having my daughter press the reset button every time is not a solution to the problem. Also she wouldn't answer my question directly when I asked her if I didn't hit the reset button and it went out of range for 2 hours again would they replace the transmitter. So I'm uploading the information to her so she can evaluate what's going on and then she will call me tomorrow with her resolution. Thought on the above anyone?
