What tune will play if I delete a tune linked to my door push button?

If you have associated your push to a downloaded tune and delete that tune, by default the push will play the next downloaded tune, if present, or it will default to one of the doorbell standard tunes. If you have more than one doorbell push, deleting an mp3 tune linked to one doorbell push, will affect the other pushes in the system. Operate each push and use the tune button to associate the desired tune.
