670g - "Do Not Calibrate. Updating Sensor" message

This happened to me several months ago and the only thing that worked was having Medtronic send me a new transmitter. After I got the new transmitter I never once got the “sensor updating” message.

It seems to me that “sensor updating” is the result of the pump receiving bad data from the sensor. In my case it was a bad transmitter, but it can be due to the sensor being moved or slightly dislodged. I tape it down very tight and secure and always use the two pieces of tape it recommends.
