There is no power.

• Press the POWER button on the remote control or on the top of your Sound Bar.

There is no sound from

the Sound Bar.

• Press MUTE on the remote to ensure the Sound Bar is not muted.

• Select a different input source (Analog or Digital).

• Be sure the audio cable coming from the TV is connected to an audio output, not an audio input.

I hear buzzing or

humming.

• Ensure all cables and wires are securely connected.

• Connect a different source device (TV, Blu-ray player, etc) to see if the buzzing persists. If it does not, the problem may

be with the original device.

• Connect your device to a different input on the Sound Bar.

How do I listen to

SRS TruSurround or

Dolby Digital?

• To activate SRS TSHD, press the Menu button the remote and use the arrow keys to scroll to the TSHD screen to toggle

between on and off.

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

available over Digital Coaxial, or Digital Optical connections.

• Digital formats other than Dolby Digital are not supported and no audio will be heard if these are input to the bar over

optical or coaxial.

I would like to adjust the

sound on the Sound Bar.

• Adjust the bass and treble levels by pressing the Menu button on the remote and adjusting the settings.

• Try enabling/disabling SRS TruSurround by pressing the Menu button on the remote and adjusting the settings.

• 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 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.
