Notes:
• Only new circuits (circuits that are not published recently)
are described.
• Figures can deviate slightly from the actual situation, due
to different set executions.
• For a good understanding of the following circuit
descriptions, please use the wiring, block (see chapter
9. Block Diagrams) and circuit diagrams (see chapter
10. Circuit Diagrams and PWB
you will find a separate drawing for clarification.
