Adjusting the image

Adjust the height of the projector, if necessary, by pressing the release but- ton to extend the elevator foot.

Rotate the leveling foot (located at the bottom back right corner), if neces- sary.

Position the projector the desired distance from the screen, so that the lens is perpendicular to the screen.

See page 36 for a table listing screen sizes and distances.

Adjust the zoom or focus rings by rotating them until the desired image size and focus are produced.

If the image is not square, adjust the vertical digital keystone by using the buttons on the keypad. Press the upper Keystone button to reduce the upper part of the image, and press the lower Keystone button to reduce the lower part.

You can also adjust the keystone via the menus. See page 25.
