NSM Festival ES2 160 -1980

I have som problems with my jukebox….. When the cabinet-lid is open the display says: [ ] [ ] [ ] [P] [P] and there are no possibillities to write any code with the push-buttons. Do You know which code to type? Do I have to type it in a special way? Nothing happens when I hit the push-buttons……

When the cabinet-lid is closed three codes appears flashing. These are the codes:

Nr.1: [1] [0] [0] [ ] [7]
Nr.2: [2].[7] [5] [1] [6]
Nr.3: [0] [6] [0] [6] [3]

After putting coins into the machine this is what appears in the display: [1] [1] [ ] [ ] [C] In this situation it´s not possible to type three numbers. It´s possible to type two numbers but when trying to type the third one the letter "C" appears on the display.
