I received a very short reply from them today and this is what it said:
That information is under the help key,
Factory-renewed - A factory-renewed product has been out of its original carton and may have cosmetic imperfections. All factory-renewed products have been tested to meet Philips' quality standards. A factory-renewed product carries a 90-day limited warranty from Philips. Factory-renewed products are exclusively found at the Philips Electronics Outlet Store.
I searched the site and never saw that, so I guess it's all on me. My next step will be figuring out where to hook it up to make sure it works because I'm not sure we'll be using it before the 90 days is up. That will be the last time I make a "big" purchase like that online.
