Hi,

when I touch the Beolab 3500 when the complete system is in standby, it starts with "Radio".

Is there any way to change this to e.g. "CD" or "N.Music"?

As far as I know - no

One reason for "Radio" beeing the default source from standby is simple:
Radio is always available - e.g. CD-tray might be empty, computer switched of,  ...

If BM5 is the sole audiomaster of your Link-System you can allocate "Radio" to start "Netradio" .
Manually starting the BLb3500 from Sys-Stanby sends the commannd "Radio" and the BM5 "translates" it to start "N.Radio"

That would make sense, I suppose that is why the A9 keyring is the same.

Ok, thank you. The Beomaster 5 tip can be the solution :-)
