I assume that you have connected and wired the device correctly (use the correct adapter if necessary). If so, you need to press and hold the music button a little longer to switch it off. Regarding the DAB transmitter: Install the Smart Sync app and read the operating instructions. P.s. Depending on the smartphone, some functions may not work properly.
