Question about Zyxel Nas542

So far, I have always received a CH mains cable if the original packaging contained a different country version. Admittedly, this has not been the case very often. However, I think it is reasonable to expect that the device purchased here can also be used here. Among other things, because the product description confirms this (place the mouse pointer over the "i" at the last point of "General Information"). I would contact the customer service without a guilty conscience.

I picked up this noble piece at Digitec Basel today, but I didn't know that I would have to emigrate to the EU! It was only delivered with a Schuko plug (cable). Is this a secret approach to the EU? Full on!
