The link is for the '70s Beomaster 6000.How that will work I'm not sure either.
Yes always unclip the plastic under the bottom of the BM6000 to see if the pc board is in place before getting the remote.
The 2035 remote and module was optional so not always installed.
I found out the hard way on this. I got a rosewood BM6000 and it came without a remote as I recall. Lifestyle had one for sale and I got that one. It's still working great together.
When the white edition BM6000 came around it needed the remote and a service so it got send to Dillen. Meanwhile I found a remote on ebay.co.uk which was rather dirty but cleaned up and a new battery it works just as well as the other + looks just as good. Anyway I got the BM6000 home and plugged it in. Tried the remote. Nothing! I called Dillen who said he did not look but check the pc board under the BM6000. I did on the rosewood to see what it should look like and the white one had no board. I then asked Dillen if he had one and yes but it was not marked as being a working one. So I got that and installed it works fine.
The 2035 remotes do come up so just keep looking.
