FM radio

Before using the FM radio function, it is necessary to carry out a search of all stations available. The radio stations will be saved to the speaker internal memory. It is therefore not necessary to carry out a new search each time you switch it on. You will only have to do this if you place the device in a new location or if you change the frequency of the saved radio station.

In order to carry out a search of all radio stations, press Change function (4), until the FM radio mode appears on screen.

Press Volume -/ Back (5) or Volume +/ Next (6) to select the radio fequency. To listen to the preset, press twice Change function (4) and the preset frequency will stop flashing on the display.

Removable storage units (USB sticks)

Plug a USB stick into the corresponding port, (2), to play MP3 or WAV files. The Home Speaker 4 Studio will switch to that playback mode automatically. Once the external storage unit has been read, music playback will start. It will only take a few seconds. Do not remove the storage unit while the reading process is in progress.

If you turn off the Home Speaker 4 Studio while the device is playing the files of the external storage unit, the internal memory will save the moment where playback stopped. If you connect the same removable storage unit once again, playback will resume from the point where it stopped.

To switch to the previous or next track, press Next (6) or Back (5). You can also switch to the next folder stored on your USB stick. To do so, press and hold Change function (4) for two seconds. To change the playback mode (shuffle/ repeat all/ repeat one), press Change function (4) twice or press Shuffle mode (11) on your remote control.

Important: We recommend not to remove the external storage unit while the reading process is in progress. Before doing that, please change mode or turn off the speaker.
