how to manual focus - Olympus C750

Olympus c-750. Problem with focus: "To get the 740 in manual focus, you hold the 'OK' button down until you see the viewfinder display a focusing scale. It takes a second or so. You should also see 'MF' and 'AF' designations in the lower left corner of the viewfinder when the scale displays. Use the left and right arrows to select the focus mode you want (i.e. MF or AF), then use the up and down arrows to adjust the focus distance. You'll notice that the area you are focusing on is enlarged when you use the up and down arrows."
