Oh, about the plug problem, I now have the following text module ;-)

------8<------------------8<------------------8<------------------8<--------

Digitec is obliged to supply electrical appliances with a Swiss plug. If the device comes with a foreign plug, a suitable replacement cable should be supplied if the mains cable is pluggable or alternatively, if the mains cable is permanently connected, a suitable adapter.

If the appliance is delivered without a suitable plug, complain to the customer service and insist on a cable or an adapter, free of charge.

what distinguishes a CH version?
