To allow the IP address of the audio unit to be reset to the default factory settings and

(SETUP) for at least 5 seconds to reset the IP address of the unit as well as the
URIs to their factory default values. The audio unit performs a reboot and
restarts with activated VoIP mode.
Note: All other parameters are not preset to factory defaults.
Note: The connection to the configured radio set will be automatically established.
