Product review (1 stars): Defective from the start!
Started beeping as soon as it was turned on. It arrived a few weeks ago, and we finally were able to have it installed.  It immediately started beeping nonstop.  We tried turning it off and starting over, but it again started beeping nonstop.  It is defective and I requested a return.  I will update this post after we see how this return is handled.
