Approximately five minutes after entering your second BG meter value, your display device(s)
will start providing sensor glucose readings and glucose level trends. While each display
device may have different ways of presenting sensor glucose readings and trends, the
meanings are the same.
Fingerstick measurements entered into one device will be available in the other
approximately ten minutes after entering data.
