Super Anleitung. Ordentliche Auflösung. Das ganze noch in Deutsch wäre zu schön. Alle Datenblätter sind sauber Kopiert und alle Leitungswege sind sauber ausgeführt

Thanks God for the internet and thanks for the service like this - proffessional solution on time.

About the service it's very fast and reliable. About the manual the quality is high enough to read even the tiniest details on the wiring diagrams so you can't ask much more than that, let it alone for a manual of a product from 20 years ago. Thank you, very satisfied.
