I want to return my
Sound Bar to factory
settings.
• Press and hold the Power, Volume Up, and Volume Down buttons on the Sound Bar for 10 seconds to return it to its
factory default settings.
When should I use
Night Mode or SRS
TruVolume™?
• Night Mode reduces bass output of the sound bar so that listening to the bar is less likely to disturb others. SRS
TruVolume™ reduces high volume content like commercials and increases low volume content, like dialog, so that you
have a more uniform listening experience. Night Mode and SRS TruVolume can be turned on independently or together.
