Quoted from Lermods:yes, in the settings, I think for devices, but it's been a while since I've had to do it so cant exactly recall. They should automatically recalibrate at start up too, but try to do it manually and see if that corrects it.
It's under Tests:Device Tests The big advantage to running the calibration that way is that you get some clues as to what's going wrong if it still doesn't work.
