Yes, I have read online that they are having problems with the 10/2009 sensors and even the new replacement sensors dated 1/10 have been conking out. Hang in there, we are. Because we think this is the best system so far.

We have had the same problem. So far, Dexcom has sent us a new Receiver. Then tech support now just sent us a new transmitter. Dex tech support could tell the transmitter was flukey due to yellow vertical lines showing up on the screen. Aside from all this, however, Dexcom is experiencing technical problems with their sensors (according to Moms/Dads on CWD website). Instructions have been to try each sensor and Dexcom will replace any sensor that fails. And, I gather a lot of them are failing....... Don't think it's right kids have to be guineau pigs for each and every sensor. So far, we have had lots of question marks, readings can be sporadically WAY off the 20 percent margin of error. I have restarted, after six hours of ??? and each sensor that I restarted did work. Stick with each sensor, restart it a couple of times before you pull it. That's the only "fix" I know of so far. I know this system works from reading all the reports on line (lots of long time users). But they are experiencing problems with sensors dated 10/09 and now the new batches they sent out are failing a lot of people. I would restart each sensor at least twice before pulling. And I might ask Dexcom to replace boxes of sensors with new working ones (once they figure out what the problem is). We will wait out Dexcom in this house, because it is comfortable for my niece to wear (she has not complained about insertion or pain on wearing ONCE). I know they will get things up and running again. However, if I could not get most of the sensors to work after a couple of restarts, I might put Dexcom temporarily on hold until they fix the problem. Nobody likes inserting these devices over and over to no avail.

In almost 3 months, I have had two sensors that gave me ???.

The first one I was able to get to work after 2-3 hours. The second one, I called it in to Dexcom and they sent a replacement sensor.
