One approach to consider is resetting the camera to factory settings, and then applying only the changes you are interested in. Doing so eliminates any mysterious changes someone in the past might have made, and allows you to configure another camera the same way (e.g., at the competition, your camera breaks, and you borrow one from someone else)
Page 42 of the manual (
