Page 66: Focusing And Positioning The Screen Image
To focus the image, rotate the focus ring (the front ring on the lens). To adjust the size of the image, rotate the zoom ring (the rear ring). Rotate the zoom ring clockwise (facing the projector) to make the screen image larger or counterclockwise to make it smaller.
Page 67 If you need to raise or lower the image on the screen, extend or retract the foot at the bottom front of the projector as follows: 1. Stand behind the projector and support the front of it while you lift the blue foot adjust levers above the adjustable foot. This unlocks the foot so it can move up and down.
Page 68: Resizing The Projected Image
3. Release the levers to lock the foot in its new position. Make sure the foot is locked before letting go of the projector. 4. If the projector is not on a level surface, level the projector by turning one of its rear feet to adjust its height.

Page 124: Saving And Recalling Effects Button Assignments
Saving and Recalling Effects Button Assignments You can save more than one set of Effects button assignments if you want to use different functions with different presentations. You might also want to save more than one set if you want to use the same functions, but apply a different look to certain effects (for example, a different stamp or pointer).
Page 125 Note: If you have multiple sets of Effects button assignments, make sure you register and name each new set. If you fail to register the set, it disappears as soon as you recall another set. To recall a set of button assignments, select its name from the list box in the upper left corner of the ELP Link III main dialog box.
Page 126: Assigning Functions To The Keyboard
