I have a Fadal vcm40 and it has been sitting for a few years. I got it fired up and when I try to set a tool length I get a parameter error. I have reset all of the parameters and same result. I checked the voltage on the battery on the board with the pink battery and it was in millivolts so I am going to order a new battery. I also checked the batteries on the 1220-3a power supply board, The batteries only show about 1/2 volt. The batteries say 3.4 volts, so I was going to replace those also but they are not available. Can I use the 3.6 volt pink batteries?

Thanks..........Todd
