Can't help you with your question. Last and only time I dealt with Pentax service was in 1982, after my ME Super had met concrete pavement.

Quote: I'm French learning German in Austria (if some Germans are reading, please don't laugh)
I am German, and I did not laugh.
I was born and raised in Frankfurt am Main, but my mother was from the southern part of Austria, so I know about possible problems. That is, if you speak a southern Austrian dialect, and make use of the hundreds of words special to the Austrian version of German, and the many exceptions in grammar which are alternatively allowed in Austria, but not in Germany or Switzerland.
However, it is not as bad as it used to be in my youth - because of the many TV series one could see in national TV using either Bavarian or Frisian dialect. These were like foreign languages to everyone not from these parts of Germany. What is called "high German" is naturally spoken only in a small region around Hannover. The Hamburg area dialect is near to that, the main difference being the pronounciation of the consonant combination "st".
You would not have any problem if the Ricoh service was in Munich, as the Bavarian dialect is very near to Austrian German. Of course everyone in Bavaria can speak (a kind of) High German, but they don't like to do it.
I am always amused when the American skiing star
Lindsey Vonn is heard on German television - she speaks quite fluently Bavarian German, because for many years her best friend was the retired German (Bavarian) skier
Maria Riesch. When Lindsey trained in Germany, she was usually living at Maria's.
