The manual for the Bosch DS835i uses the word "range" for the only uWave
adjustment provided (via a potentiometer).  Maybe that's how they translate
Empfindlichkeit (sensitivity) and Verstärkung (amplification) to English
(It's them pesky words and definitions again ;-)

What is the difference between "range" and "sensitivity" in the actual
physical  adjustment being made ?
