Lloyd,
click on the attached that gives you a google search of various videos demonstrating the LevelUp system. It may help you. As you've noted in some responses so far to your inquiry, some use Manual and others rely on Auto. Practice and usage will strengthen your understanding. Hell I'm still a little shaky with it but so far no real issues using it. Good Luck
