Thanks Patrick,

Pocketbook asked me to send in the Inkpad for service. I am not going to do this .
However I tried to plug in a service cliënt cable and it started tot work right away. I could't check the sound of course but I agree with you abouty the dongle. Must be something wrong with it.
So I suggested to support tot send me a new dongle.
So I will have to wait and see.
