Context:  Recently purchased, lightly used Beosound 9000 Mk II.  Connected via Powerlink to Beosound Core/Shape.  Both manual operations at the operations panel, as well as remote operations (Beo4) function as expected.  Lovely unit. Issue: When placed in ‘remote mute’ (A. Opt. = 0), some of the functions of the manual operations panel become compromised. In Option 0 mode, the left-most cluster of buttons on the panel don’t work.  The reset, mute, volume up/down buttons don’t function.  Nothing is displayed when they are pressed.   Treble, bass, balance, loudness cause the following message to flash on the display: “TV Operated.”  I don’t have a TV in the room, and my only TV in the house is not a B&O unit. Note that in Option 0 mode, it’s still possible to manually select a source (Radio, CD), it’s still possible to manually advance the track on the CD or select a Radio station. Subsequently placing the unit back in ‘remote receive’ option (A. Opt. = 1) returns full function to the manual control panel.  At all times and with both options, Powerlink remains cabled to the Core. I hope that this is a settings issue, and some kind soul here can suggest the magic button sequence that will provide full manual operations in Option 0.  Thanks!
