Upgrading to Software Version 3.4 provides the following functionality
- PIN code active from factory
- Option 5 and 6 introduced. Option 5 is to be used if there are two IR eyes in the same Link room; e.g. BeoSound 9000 and BeoVision 6-26.
- Option 6 is to be used, if there is one IR eye in the Link room.
NOTE: There must always be Power Link speakers connected to an audio product when using option 5 and 6.
The following problems were resolved:-
- Timer play not executed if a Standby timer has been activated.
- When listening to N.MUSIC in both Main Room via BS9000 and Link Room (Beoport), and standby button is selected from the Link Room, then the BS9000 also goes into standby.
- Red button for genre does not work when N.MUSIC is playing on BS9000 MK III type 2571. Other coloured buttons work OK.
- Automatic option (PL plug on/off) does not work from option 1 to 0.
The Beosound 9000 software is updated by replacing a chip in location 3IC1
To order the software it has a part Number of 8344070
However, unless you have one of the above issues, I would not update the software.
