BS Balance has been and still is working fine as far as I can tell.  Normally the microphone is turned off.  Recently I wanted to rerun Room Compensation so the microphone was turned on (via switch on bottom of Balance).  Room Compensation routine finished and microphone was turned off.

Now the Balance displays four orange LEDs in the middle of the set of volume indicator LEDs.

The orange LEDs remain on solid whenever the Proximity sensor activates.  Exception is when volume is actively being adjusted, then all volume indicator LEDs are either white or off.  Shortly after volume adjustment is stopped the four orange LEDs turn back on solid and remain on until the Balance goes into standby.  In standby, only the center network status indicator remain lit.

Somehow Favorite #1 had changed from a chosen radio station to Chromecast after running room compensation and/or turning the microphone on/off. Resetting the Favorite back to the preferred radio station had no effect on the four orange LEDs.

Any clues as to what the four Orange LEDs on the volume indicator arc might mean and how to turn them off are appreciated.

Thank you,
