Notes: The German brand SERD has a series of calculators named to German towns. This one is called Kiel. "Kiel lies around 100km south of the Danish border, directly on the Baltic Sea and the 17km long Kiel Firth" according to a German tourist info site (link lost 2002-10-27). Kiel has a homepage (link valid 2022-12-30) as well. Other ones in the series are named after Aachen, Berlin, Bremen, Hannover, Köln and München.

Anyway, this is a plain calculator with a change-sign button and percentages.


A power adapter.
