Display and Operating Elements
The pressure-sensitive membrane of the front panel consists of a plastic coating. All keys have been designed as
touch-sensitive membrane switch elements. The display is a LC-display, consisting of 2 rows of 16 characters
each, with indirect green lighting. The contrast of the display can be infinitely adjusted via a rotary potentiometer
positioned on the right side of the control.
