Please set on trial basis two stops ahead. Monitor the display of the IBIS and listen to the validating machine.
Setting stops ahead can be done on IBIS by clicking the "Next" or "Next muted" button or with the foot switch on the bottom left, operated with the [Q] key. The foot switch opens the microphone, which allows you to announce the next stop for your passengers.
Turn back to "Krankenhaus" by pressing button "Back mute" on IBIS.
