Hi! Did you find how to pair the speaker? I am having the same problem if you do it please share how to with me.
I contacted Rca and this works.
CONNECT THE WIRElESS SUBWOOFER MANUALLY
If the wireless link is deactivated, you can connect it back manually.
1. Select OPTICAL IN mode.
2. Change to 5.1 surround mode by pressing the SURROUND button once on the remote, the BT indicator on top panel of the soundbar will flash.
3. Press the WIRELESS LINK button on the back of subwoofer for 5 seconds, the blue WIRELESS LINK PAIRING indicator will start to flash.
4. Press the (PLAY/PAUSE) button on the remote for 3 seconds, the OPTICAL IN indicator will start to flash.
5. Press and hold the (PLAY/PAUSE) button until the blue WIRELESS LINK PAIRING indicator turn to solid.
