Only ever having to deal with 110v System 1, I thought it was the case with system 80 - great to know for future reference. But for system 1 (which would have saved me some $) - the manuals for system 1 don't show the jumpering - how would that be done Owen, exactly the same?

Yep, exactly the same - that's why I only showed the SYS80 manual as it was the clearest one I had here.

And yes mate, they do show the wiring - it's in the dotted box to the left of the standard 110V wiring... the one marked 230V.
