Have an RF-WS02 speaker with its Sender RF-WS02/03 and they work well together. Just bought a used RF-RBAUX (condition unknown) and I cannot get it to work with either of them i.e. can't get the speaker to pair with and receive from the RBAUX. Can't get the Sender to pair with and transmit to the RBAUX. Studied all the manuals. Is this Speaker or its Sender (or both) pairable with an RF-RBAUX? Thx
