I have never done it, and you said you have the manual. I just like to pass on this site I recently found. Here is the link. The first link is to the main site, and the second link is to the overview page, the third link is directly to the bravo 1 section. I haven't read everything, and I don't have a bravo 1, but I am guessing it is in this site somewhere.
