The on-board monitor control panel features a 12-pin, blue ELO connector.
The lines for power supply, the I-bus link as well as the line for button lighting are routed to the on-board monitor control panel with cassette drive.
The audio frequency lines of the cassette drive, designed as twisted, non-shielded lines, are assigned to a part of the connector.
Only one connection line for switching on and off and for brightness control of the LCD on-board monitor (PL line) is routed to the monitor.
