If it's like the E-M1, you have a very flexible camera with unavoidably complex menus and commands. The way I approached the Em1 with its 170 page manual was to make a list of the dozen or so settings I need to change regularly, look them up, and make a cheat sheet. I've pasted this below in case your camera has some of the same controls.
