It looks like a bad contact but probably not in the cables
rather something in the radio/display.
I think it would be wise to connect them without
RRC's and see if it happens also but since they are separated 700km
you need help from somebody in that area
who also has a 706 and connect his display to check it out
but then only one part is checked.

Guy,
I agree, bad contacts are the first thing that comes to mind and what has to be checked before we think about any more complicated causes. The effect that pressing POWER makes the status of both RRC "Connected/Tranfering" but leaves the display dark is specific to my remote location and/or the nework structure of the two providers involved, Kabel Deutschland at the radio and Telekom at the remote site.
I moved the remote RRC and the control head back to the location of the radio, now the display comes up immediately. To make the test more realistic I used again two separate WLAN-networks and two different providers, Kabel Deutschland and German Telekom -- everything perfect. I am very staisfied with the qualitiy of the remoterig.
There is apparently a two stage process, (1) establishing contact and transfering control information. When this is completed you hear a beep tone. (2) transfering data for the display and audio to the speaker.
