hi this is my first time to ever post and hope im doing it right i have a makino edm ec 3025 approx 1988
i havent used it in a month and i turn it on and get a alarm code 0020 battery drop the book says it might be in the power supply but i cant see a battery i tried makino but they wouldnt help me unless i gave them $2500. for phone support and i dont think the machine is worth much more then that.
dose anyone know where the battery might be located or what board i need to have repared
