Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
Does any error message show on the treadmill's console, when the beeping sounds?
Does the beeping have any pattern?
Do you still have the sales receipt for your treadmill, perhaps? or credit card records of the transaction?
Let me know, by using the Reply To Expert function, and I will advise you as to what to do about what is, most likely, wrong with the treadmill.
