Henni,

I believe your REGISTRATION - NUMERIC value is ON - which means AUDYA is asking for you to enter a numeric value associated with the register (default AJAMSONIC setting which is vital for live use) whenever you press F2 (from the default screen)/Registration buttons.

From the default screen, press REGISTRATION (the actual button), and set NUMERIC=OFF (User 3/8) to return to the screen setting and functionality you mentioned above.

Thanks,
