DIAGNOSIS The wireless connection between the soundbar and subwoofer is lost. The subwoofer is powered but not receiving a signal.
FIX Power off the soundbar. Locate the ID SET button on the back of the subwoofer. Press and hold it until the LED on the sub starts blinking. Power on the soundbar. The LED should go solid once paired.
IF THAT DIDN'T WORK Move the subwoofer. Place it within 3 meters of the soundbar, away from large metal objects or direct walls that can block the 5GHz wireless signal. Repeat the pairing process.
HEADS UP The subwoofer LED should be solid, not blinking, during normal operation. A blinking light indicates it is in pairing mode or has lost connection.
