WPC CPU board
Question: I installed the new PinLED WPC CPU board in my pinball machine. After switching on, the error message always comes up that the pinball machine has set to the factory data.
Answer: The RAM memory is buffered by the battery after switching off. The battery ensures that the settings are present again the next time the pinball is switched on. The internal clock also continues to run. So that you always find a fresh battery after purchasing the CPU board, the battery is switched off in the delivery state. There is a switch on the "jumper" DIP switch that must be set to ON so that the battery is connected.
