        Thank you sofar Mike.
FYI I use USB for connection.
I followed you instruction 1) and linked 2 new registration banks with no memory button active: no problem. When linking I receive the message “System exclusiv
But I need to link the memory buttons as well because I have a different song sheets for every button. For this I follow your instruction 2). When linking I receive the message as given in photo (batch command).
Most of the time this goes well but sometimes the sheets do not change with the button. It is difficult for me to explain but let me try:
I linked all memories in a bank and notice that memory 1 to 8 are linked correctly but memory 9 and 10 do not link. If I try to correct this by repeating the procedure for memory 9 and 10 then the linking for 9 and 10 is correct but the linking of 1 to 8 has disappeared. 
Please note that this happens in the situation that I choose a memory to get the music sheet. If I do it the other way around (choosing the music sheet to get the correct memory) it functions well. It looks like the problem occurs only when sending midi data from genos to mobile sheets and not when receiving.
I noticed another strange behaviour: normally one can change registration bank by using the + or - button of registration bank. In case that the link function does not work it is not possble to change bank with + or - button, only via menu. I do not know if this has something to do with ithe problem.
I hope you can give me suggestions to solve this.
