Hello and welcome. Perhaps as a suggestion, since the forum is in German, it would be helpful for everyone's convenience to use a translator like I do. I write in Spanish from Spain and respect the original language, although it makes me uncomfortable not being able to express myself as I'm used to. That said, in my case, I don't regret it at all. You'll just have to make sure there's no phantom power consumption from the unit. I don't know why, but many Chinese radios, regardless of the model, have phantom power consumption. You can choose Celsius or Fahrenheit, and all the information you want, be it hours or temperatures. They are usually very complete and quick to use. I wish you luck!
