For some reason, I can't edit my last post.
Anyway, here's the setup manual for your ESC;
www.ftp.ansmann.de/Brushless_Set_Xirius.pdf
The link isn't working for me from here, but if you go to the Ansmann.de website, enter " manual " into the search box, then scroll down to your ESC,then the pdf setup manual is available for download under the brushless subcategory.
