It actually on page 4 of the manual (its item 7 on the menu) not on page 7. The manual doesnt tell you but you need to move the ratchet from the right stick to the left stick.
In the PDF file I linked to above it is on page 7. While the text doesn't say about the ratchets, the diagram does show where to relocate them to.
