I have a TEC MA-1400A cash register. The power went out last night and this morning all the little triangle keys are lit up and nothing works. I have tried unplugging it and turning it off. But, I can't get the register to work. No keys do anything. How can I fix this?

Hi. You haven't had the battery replaced on time (every three years recommended). You have now lost everything from the machine. It will need to go to a TEC dealer to have all of the system programming replaced. If it is in poor condition then it may not be worth repair.
