What I did with ours was, turn all but one of the valves off, operate the slide control to see which slide moves. Use a Sharpie to make your own label, (bed, kitchen, etc). Then close that valve and open the next and do the same thing, and then continue with the remaining valves. DS means door side, ODS means opposite door side, I think AS means auxiliary slide, but not sure what the OSS means.
