I got a call from my cardiologist office on yesterday that my device was beeping. I heard a beep but I thought it was coming from something in my house. I did not realize it was me. I got my device in 3/2009 and this is my first battery change. I went in today and they turned the beeping off and I will schedule a precedure to change the battery. I was just wondering is their anyone besides myself that did not realize the beep was them.
