I was wondering if there was one. I went to the Horizon site looking for it but it wasn't with the downloadable manual.

I just called Horizon and they told me there is no addemdum for it. They were very happy to help me if I had a problem though... I told him that I had several small problems that were resolved now, but I was hoping to aviod any others. He said to call back if I run into anything else.
