RE-LINKING THE SUBWOOFER WITH SOUND BAR
Your Subwoofer has already been paired with your
Sound Bar by VIZIO. However, you may need to pair
the Subwoofer to the Sound Bar if there is no sound
coming from the Subwoofer.
When the green LED on both the Sound Bar and
Subwoofer are lit, the two are paired. A slow blink
means the two are not paired.
