Multiturn potentiometer
A removable operating button is plugged into the multiturn potentiometer at the factory. The setting of the contrast sensor can thereby be

for the setting.

Press the C button longer than 12s.
Release the button.
To change the setting again, push the button
again for longer than 12 s and release.
