My DM3200 has been acting up….freezing, horizontal lines on screen, error messages popping up all the time, just so frustrating despite resetting back to factory and opening up and replacing the battery with a new CR2032 battery. Still acting up after a couple of hours, same deal, errors and horizontal screen lines. Opened it up and replaced the battery with a BR2032 and it’s back to normal…well two full days now without any problems. I have no idea why but I’m just posting this in case anyone else is having similar issues.
