Heiko - welcome to the forum.
There are several members here with Y62's. Unfortunately, us poor folk who cannot afford them all have Y60's / Y61's.

As such, I'm totally the wrong person to ask. I could point you at the reference library which has various manuals and similar. However, there is, as far as I know, very little associated with the Y62 there...
I'm sure one of the Y62 members will see your post at some point and respond accordingly. But unfortunately, the WhatsApp groups appear to be more active than the forums these days. I say unfortunately as a believe a large amount of information is "lost" in this way.
I can add you to the WA group if you like and you can ask any questions there ? If I can just ask a favour - please post anything interesting you learn here so that we have some searchable record for it. :)
Send me your cell number if you want me to add you the QA group.
