Speedometer A
A speed can be simulated under this menu item to check the function of dynamic volume control (speed-dependent volume). If the function of the
dynamic volume is switched on and the speed is simulated by means of the Porsche System Tester II No. 9588, the volume must change according to the
speed. The higher the simulated speed, the higher the volume.
