When a key is pressed this key or its function is displayed. This can either occur by a triple
character display, e.g., "AAA" or as a text, e.g., "CURS_UP". Moreover, pressing the "B" key
tests the bleeper (audible sound). The keys "ALT" and "SHIFT" only in combination with
another key. The "E" key terminates this test and simultaneously undergoes a self-test.

The speed select key is used to set the required speed and the motor is set into motion with
Start/Stop.
A marking pulse is set once every second. The running speed can then be calculated or its
accuracy checked from the distance between marking pulses. Any other key pressed not
included in this menu leads to the initial display menu.
