Why, did it not work? You can append an "L" to most sheet designations to get at the lower screen. Go to: http://www.petitcomputer.com/manual/manual.pdf and go to page 98. If you look through that list, you can find the designations for many of the sheets. However, note that quite a lot of them have typos, so you'll just have to keep trying them until they work.
