Active sound source:
In this product there is four different sound sources possible to control the volume of, level dependent,
built in communication radio, Bluetooth stream and Bluetooth call. For example if there is no activity on the
built in communication radio and no activity on Bluetooth link, plus and minus button is controlling the level
dependent volume. As soon as there is an incoming call on the built in communication radio, plus and
minus buttons will control radio volume level. Should the end user instead have an active audio stream or a
call via a Bluetooth connection, plus and minus buttons will control Bluetooth volume.
