when i turn on my er-150 sumsung electronic cash machine its saying error and making a loud buzzing sound so at the moment i cant use the till, i belive i need some sorta code to set it straight again does anyone know the code plz :)
If it is a continuous buzz, then you may have changed modes without finishing. turn the key to see if it stops buzzing in a certain mode (apart from off mode). If it does, finish what you were doing in that mode, then turn the key.
