When you play audio that contains a limited amount of low sounds (television programs, etc.), it may be difficult to verify if sound is coming from the subwoofer.
Use the following procedure to playback the internal sample music and check whether sound is coming out of the subwoofer.
- Press the INPUT button or button on the Sound Bar for 5 seconds to playback the internal sample music.
- Press the INPUT or button again to end playback of the internal sample music and return it to its former state.
