Hi There, 

i bought a BEOLINK 7000 to use it for 2 Way Communication with my BEOSYSTEM 2500. After i canged the Akku it is worlking in 1-Way Mode. I have read everything in this Forum before i posted this. 

I see that the Beolink is sending Data (It worked as a One-Way and i cheked it with Videofunction on Phone)  also i see ste Beosystem 2500 is sending Data back (Also Checked with the Videofunction).

I tryed Remove and at Radio several times in diffrent Modes (Also STANDBY Mode ;-) I also tried it in a diffrent Room. I see that the Beolink is sending and i see the Beosystem is responding. 

So the only thing missing is that the BEOLINK is not reciving Data. For this reason it says "NO Connection".
Some told others with the same problem to change condensators (elkos). But my System is sending Data. Is the System also reciving the Data through the same IR-Diodes? 

Also i am wondering if there is any body out there with another tipp how to repair or someone that offers a repair?

For your Information: i also checked Mode 1 and 2 for the different operating Modes.
