The S/W differences are minor.
The following modifications were made:
1. The fault in the PLAY NEXT function has been corrected.
2. Beomaster 4500 does not transmit IR status when option 0 mode is selected.

Unaware of a DAB receiver that will work with the 7000 though you could use a TV and an STB-C I suppose and obtain Freeview radio stations. MX7000 maybe?

🤒You impress, me sir! I do wonder where one would get such kmowledge from.

How just one change the Beomaster into mode "0".  I pressume there is a mode where the Beomaster 4500 does transmit (a switch between "one-way" or "two-way" commmunicarion). Which other modes exists?

What was the fault in the "PLAY NEXT"-function?

I hoped that a softwar up grade would do more than correct some faults - maybe some new "magic" functions would come to the world. But maybe my expectations are too high.

Nevetheless, thank you so much for your quick answers. Maybe some body else have additional knowlegde (even though I am impressed that anybody could display such detailed knowledged as you have just done (pardon my English - I am Danish). I hope I am just reasonably understandable.

Best regards

Most software changes are to correct small faults, most of which go unnoticed by most users. However there are big changes at times - usually they change the first number rather than the decimal.

Option setting is what the mode 0 refers to

Option 0 switches off the IR eye

Option 1 lets it receive audio commands

Option 2 allows it to receive both audio and viseo commands

Option 4 means one has to press LINK before each command

Option 5 is for when used in a link room with a TV also in the room

Option 6 is for link room use and allows both audio and video signals to be received.

The 4500 is actually slightly more complicated but this is in the manual.

To set Option 1 for instance, with the system in standby, use a Beolink 1000 and press Sound 1 Store.

Hi,

I  have managed to "destroy" the IR-reciever (when I repaired a transistor in the power PCB) of my 4500.

The IR-recieverit works if I pull out the IR PCB from the system and aim carefully at the IR-diod.

Any Idea how to fix it?

I think I have checked the transistors, diods and capacitors properly.
