1) You should find the error code. This is a code coming from your C2000 controller not your bill acceptor. (This light is indicated with the blue arrow.) The code has 2 flash patterns and a pause in between the flashes (I included the error chart to help).
- (In normal operation the light should be green. Green is the only color the light can be. 🙂 )
2) Next you fixed the code issue…. Add coins, fix something! 🙂
3) Push the reset button if required. The reset button is indicated by the red arrow.
