I lightened the picture of the 780:

I don't notice anything else on the
780 besides those flanges, The 8500
also has flanges but they aren't
uniform, however the screw pattern
are the same.

So if it has a slider set it to 110V?
and should I leave the power switched
on or do I have to switch it on/off each
time?

Thanks,
Robert
