No problem. Connect the Swisscom Box to the AUDIO-In input on the system using a 2-pin cable. With the Swisscom Remote Control, select the RADIO function and then dial the station numbers with the keyboard. The TV itself does not have to be switched on, but it is necessary to know the station numbers (the order of which can be programmed by the user). Caution: If the TV set is switched on at the same time, the sound from the TV and from the system is not completely synchronous, there is a kind of echo effect. Therefore, simply switch the TV to mute so that the sound comes only from the system.
Alternatively, you could also connect the AUX-in input on the system with the headphone input on the TV using a jack plug and thus transmit the audio signal from the TV to the system (as an alternative to a sound bar).
