9770 is telling me that I need to do a feederhouse speed calibration once header is hooked on.
Ok, so no problem, except at the end of calibration procedure when you hold the button down, it does its thing and lowers head to ground, it tells you to continue holding. It never finishes, I can hold for 20 minutes and tells me to keep holding, and it never finishes.
