With my poor hearing I couldn't tell you if dinged, donged, or whatever, but it does display "OK" on the screen when the code is learned (displays "failed" if it didn't learn). Just because it says OK doesn't realy mean it learned the correct code, it learned something and you need to test it to verify that it is correct.

The beep it would be nice to have for all you young people that can hear those things.
