You can use your Wave® music system as an expansion speaker for a Bose® link-enabled Lifestyle® system. Your music system comes from the factory ready to operate in a Bose link network using room code B. If room code B is assigned to another Bose link product in your home, you will need to change the room code. Make sure the room code set in your Wave® music system matches the room code set in the Lifestyle® system remote used in the room. An additional expansion remote will be necessary to use this as an expansion product. Refer to your Lifestyle® system owner's guide for more information.
