When replacing the Mainboard you have to backup the parameters of the old board first. Either with a memory card or print them off and enter them manually with the keypad. I have been told that the sheet that I have printed off does not contain all the parameters needed. I just wanted to know what should be on that sheet.
Also the manual say there are parameters on the mainboard that can not be backed up. What are these and what do you need to do on the new board to reset them?
