Increment Sensor Test (Volume)
As in the case of the test for the button function, visual feedback takes place with each sensor increment.
Shown in the main display is a two-character counter beginning with the dual character "_ _". With each increment to the right, the value increases by one up to a maximum of 36, which corresponds to one revolution. If rotation is carried out to the left, the value decreases by one.
The test is concluded by calling up a new test from the test menu or through general exiting of the function test via the time out or switching the ignition off.
