I have an older SMH10 unit that still is going strong.  Recently, I have encountered a strange behavior.  I have the unit paired to my Samsung Galaxy S8 phone for playing music and making/receiving phone calls.  While playing music through the unit, about every 20-30 minutes, the music simply stops.  If I wait about a minute, I hear a single beep and then I can press and hold the jog-dial button until I hear the standard double beep to start/stop the music.  If I do not wait about a minute to hear the aforementioned single beep, then pressing the jog-dial button to get the double beep does nothing.  If I turn the unit off and back on again, I can start the music back playing immediately.  Any advice on how to fix this problem would be appreciated.
