Just bought a Klipsch RSB-6 Sound bar system with wireless subwoofer. Subwoofer paired one time but after a few minutes just cut off. There are no longer any lights on speaker burning. The manual shows a button (to hold down) and a light (which supposed to flash until it pairs and then burns solid). There is no button on this speaker to push. Bottom line, the Woofer is off and cannot get it back on. Another forum says to unplug for a while, then reconnect and also check the connections to ensure nothing had come loose. Done both of those with no luck. Any help would be greatly appreciated.
