Turn the focus ring to adjust the focus at the center of the screen. The focus at the edges of the screen may not be as sharp as at the center of the screen. 2. If the focus cannot be set correctly at the center of the screen, it will be necessary to move the lens unit forward or back relative to the flange in order to adjust the back focus. Carry out this adjustment according to the procedure given below. Focus Adjustment(For LNS-W11) -6- FOCUS RING ROULETTE PIN NOTE: Please remove 3 pins when you install it in the cabinet of B type. a.

If the current focal point is somewhere forward of the screen, turn the focus ring clockwise; if the focal point is somewhere behind the screen, turn the focus ring counterclockwise, and then turn the precision lens unit (the focus ring and the fixing roulette) 5 degrees. c. Turn the focus ring to adjust the focus at the center of the screen. (Be careful not to move the whole of the lens unit at this time.) d. Repeat steps b and c until correct focus is obtained. Note: If the lens unit is difficult to move when carrying out the above procedure, turn the fixing roulette counterclockwise a further 1/4 of a turn. e. Once the above adjustment is complete and the picture is in focus, turn the fixing roulette clockwise until it is tightened securely. Do this carefully, otherwise the focus may become disrupted. If the roulette is not tightened securely, it may become difficult to remove the lens during lens replacement. 3.
