Operation

Start and Cancel, Push-To-Talk button (PTT)




The system is started using the Push-To-Talk button on the multi-function steering wheel.

In SVS mode, the Control Display requests a change in status. The Control Display requests two audio channels from the Audio System Controller (ASK). One channel comes from the microphone to the SVS and the other channel from the SVS to the front door-mounted loudspeakers, left and right.

The SVS transmits the change in status to the Control Display. There is a chime generated by the ASK to confirm that the SVS system has been initialized, the recognition dialog begins (system waits for command).

By pressing the PTT button again, the dialog can be ended. The dialog can also be ended at any time by voice, using the "Cancel" command.

Shut-off

While the dialog is active, the Control Display (as system master) can interrupt it (e.g. for a priority audio output). In this case, the Control Display sends the status request "interrupt" to the SVS. There can then be no output on the audio channel.

The Control Display informs the SVS as soon as the recognition dialog can resume.
