Hello. 

I have a following setup:

Beosound 3000 connected to Beolab 2000 link speaker via ML cable. They're in the same room. I have read the manuals and it suggests to use L.OPT 2 or 4. For some reason I can't change the volume on Beosound 3000 buttons. I have tried different A.options on BS, too. Does anyone know what options to choose and/or tell me how this kind of combo is "speaking" between each other?
