Operating instructions
^ Various functions (modules) can be allocated to a certain button depending on the lettering of the operating field.
^ Some buttons have a double function (switching a module on and off). Some buttons are locked together.
^ A function indicator is allocated to each button: some function indicators are used to display errors (frame flashes on and off) as required.
^ Buttons that are not operating (e.g., no add-on control unit exists) can be recognized through different "chime signals".
^ Furthermore, the so-called rear warning lamps can be actuated.
