Occasionally when I enter the number for a BG prompt, the monitor keeps asking for it over and over and over. I know it asks for two readings when a new sensor is installed but this is much more than that. I believe it is occurring when I am much higher or lower than normal. One time I put in a more normal number as a test and the prompts stopped. Then I needed to put in the right number to make the data accurate. That sometimes causes a sensor error. Anyone else have this problem?
