THANK YOU, Nige, for your 2016 message about holding the Start button for 6 sec. I just acquired a Neff Microwave, and the infinite beeps were making me mad, and I hated the device because of that. Now it only beeps 3 times and stops.
I don't know why that is not disclosed in the User's Manual. I read it, and there was nothing.
