FYI guys with newer k machines. there is a service bulletin FSB#04-FRK-005 Rev A. that has to deal with the calibrating the new colin BP modules. They replaced the BP modules with better ones but didn't update the calibration software. so the new inflation and leak values aren't correct in the service software. That way you can disregard the fail boxes on the service screen and use the values in the bulletin. I guess this is just more fresenius goofiness.
