1. Start playing music on 1 radio. You can start music play by pressing a preset on the radio, searching for and selecting a station, via your included remote control, or the smartphone remote control app.

1. On radio 2 to select ‘audio services’ the scroll to the bottom of the menu and select ‘multiroom’ then select ‘radio 1’ or whatever network name you gave it and the music will start playing on radio 2 at the same time as radio 1. Continue ‘step a’ on any other radio on your network.  OR
2. You can open up the smart app then drag and drop the radio that you want to follow the same music that radio 1 is playing on top of radio 1.  This will create an audio group and all radios in that group will play the same music at the same time.  Keep on adding as many radios as you like up to 10 radios.
