Sorry for the inconvenience, this item comes with an ‘Auto Standby’ feature activated, which will automatically power the sound bar off after about 20-minutes of not receiving an audio signal. Some televisions may cause the sound bar to turn off in the middle of a program due to a weak audio signal.  If you find that your AccuVoice TV Sound bar is turning off while you are watching TV, you can follow the steps below to disable that feature:  

While the speaker is Off/Standby. (4 amber/orange flashing lights), press and hard hold the power button on the ZVOX remote for 5 seconds, blue & amber/orange indicator lights will flash on the display indicating you have successfully removed the auto standby feature.

The system should not shut down or turn on automatically and if it does please contact us Here, 866-367-9869, or email info@zvox.com
