The remote
isn’t working.

• Make sure the plastic tab has been removed from the battery compartment. 
• Replace the remote battery with a new one.
• Point the remote directly at the Sound Bar when pressing a button.
• If using a Bluetooth connection, some of the buttons on the remote may not be supported by the 

streaming application. (e.g., a music streaming app may not  support the Back/Fast Rewind button.)

How do I listen to 
SRS TruSurround or 
Dolby Digital?

• To activate SRS TSHD, press the 

Menu button on the remote and use the arrow keys to scroll to the TSHD 

screen to toggle between on and off.

• To listen to Dolby Digtal, your device must be playing content in Dolby Digital format. Dolby Digital is 

only available over Digital Coaxial or Digital Optical.

I would like to adjust 
the sound on the 
Sound Bar.

• Adjust the bass and trebel levels using the remote
• Try enabling/disabling SRS TruSurround.
• Disable Night Mode if bass level is too low by pressing the Menu button on the remote and adjusting 

the settings.

I want to return 
my Sound Bar to 
factory settings.

• Press and hold the 

Power, Volume Up, and Volume Down buttons for 10 seconds to return your Sound 

Bar 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. • To listen to Dolby Digtal, your device must 
be playing content in Dolby Digital format. Dolby Digital is only available over Digital Coaxial or Digital 
Optical.
