Can someone tell me what a Bang & Olufsen Programmer is for? Looks like an oversized cell phone / mobile phone or poorly designed remote - and appears to be a service instrument. It has rs232 and power-plug-in on the lower shorter side and a masterlink socket on the upper short side ...

any info greatly appreciated! 

There was a previous thread with pictures about this. Used for setting up analogue Satellite channels. We do actually have the user guide!! Pretty useless these days! Works with the Beosat LM and AV.
