Focusing and Positioning the Screen Image

When an image appears on screen, check that it is in focus and correctly
positioned on the screen. To focus the image, rotate the focus ring, which is the
outside ring on the lens. To adjust the size of the image, rotate the zoom ring,
which is the inside ring. Rotate the zoom ring clockwise to make the screen
image larger or counterclockwise to make it smaller.
