You can see on the back that the power cable is plugged in. It is therefore no problem to deliver the device with a correct power cable without an adapter. Unless Digitec once again doesn't want to...
Regarding the belt, take a look at the instructions

Digitec (or any other Swiss dealer) is obliged to supply electrical appliances with a Swiss plug. If the appliance is supplied with a foreign plug, a suitable replacement cable should be supplied if the mains cable is pluggable or, alternatively, a suitable adapter if the mains cable is permanently connected.
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.
