Sorry, I should have said to search for both "Phönix AND Phoenix Nahmaschine" as well as searching for "Class 283F", "Kl. 283F" and "Klasse 283F" to cover all possible listings in German and English!
How did you go with this Therese?
I have a Phoenix 250 and no idea how to use it. Can't find a manual anywhere, but I think Phoenix machines are more common in Germany. Try searching for Phönix as well as Phoenix when doing internet searches, if you haven't already.
I'd love to share knowledge with another Phoenix owner but I don't have a lot to offer at this stage!
