When I needed sleep most, this thing started chirping at 4 am. I didn't even know what it was...after research and YouTube videos, determined it was the door bell and learned how to disconnect it. Even that didn't really help...continued to chirp for at least another hour. :( Very mysterious and frustrating. On top of that my bedroom tv cable box quit working so I couldn't watch The Today Show in bed drinking coffee and spend a good hour working with the cable company (unsuccessfully) and the volume on my living room set was all wacked out and needed to do research to figure out what was going on there. A rough morning, to say the least.
