Wouldn't you Kno it -- sorry, we couldn't resist -- the Kno has found its way into the confines of FCC's labyrinthine headquarters. But not just one version, no sir / ma'am, the FCC tested both the single screen and dual screen versions together, it seems. External photos of the pair (or is it triplet?) can be found within the same entry, and while the user manual is also included, there's nothing to glean from it. Feel free to enjoy the iconic photography all the same!
