20 2. Projecting an Image (Basic Operation) Applicable lens: NP11FL With the NP11FL lens, adjust the focus and picture distortion. Preparations: Turn the lens shift dials (vertical and horizontal) on the projector to return the lens shift to the center. Approximate lens center position (explained here for the desktop front projection mode) Horizontal dial: First turn the dial to the left edge, then turn it further so that the knob is horizontal. From this position, turn the dial 1 full turn clockwise. Vertical dial: First turn the dial to the bottom edge, then turn it further so that the knob is horizontal. From this position, turn the dial 2 full turns counterclockwise. 1. Turn the distortion ring to the left edge. 2. Turn the focus lever clockwise and counterclockwise to adjust the focus at the center of the screen. 3. Use the distortion ring to correct the screen’s distortion. (This also brings the edges of the screen into focus.) 4. Use the focus lever to adjust the screen’s overall focus. * If the focus at the center of the screen is off, turn the distortion ring a little counterclockwise. The focus at the center of the screen can now be adjusted with the focus lever. Distortion ring Lens shift dials Focus lever
21 2. Projecting an Image (Basic Operation) Adjusting the Tilt Feet 1. Turn the left and right tilt feet to adjust. The tilt feet lengthen and shorten when turned. The height of the projected image is adjusted by turning the left and right tilt feet. If the projected image is tilted, turn one of the tilt feet to adjust the image so that it is level. - If the projected image is distorted, see “2-6 Correcting Keystone Distortion” (→ page 22). - The tilt feet can be lengthened by a maximum of 20 mm. - The tilt feet can be used to tilt the projector by a maximum of 4º. NOTE: • Do not lengthen the tilt feet any more than 20 mm/0.8". Doing so will make the tilt feet’s mount section unstable and could cause the tilt feet to come off the projector. • Do not use the tilt feet for any purpose other than adjusting the projector’s projection angle. Handling the tilt feet improperly, such as carrying the projector by grasping the tilt feet or hooking it onto a wall using the tilt feet, could damage the projector. Zoom Turn the zoom lever or zoom ring clockwise and counterclockwise. - The separately sold NP11FL lens does not have a zoom ring. Zoom ring Up Tilt foot Down
22 2. Projecting an Image (Basic Operation) Correcting Keystone Distortion When the projector is not exactly perpendicular to the screen, keystone distortion occurs. To overcome it, you can use the “Keystone” function, a digital technology that can adjust for keystone-type distortion, resulting in a crisp, square image. The following procedure explains how to use the [KEYSTONE] screen from the menu to correct trapezoidal distor- tions. When the projector is placed diagonally to the screen, When the projector is set up at an angle in relation to the screen, adjust the Horizontal option of the Keystone menu so that the top and bottom of sides of the projected image are parallel. 1. Press the GEOMETRIC. button on the remote control or the projec- tor cabinet. The Keystone screen will be displayed on the screen. 2. Press the button to select [VERTICAL] and then use the or so that the left and right sides of the projected image are parallel. * Adjust the vertical keystone distortion. 3. Align the left (or right) side of the screen with the left (or right)\ side of the projected image. • Use the shorter side of the projected image as the base. • In the right example, use the left side as the base. 4. Press the button to select [HORIZONTAL] and then use the or so that the top and bottom sides of the projected image are par- allel. • Adjust the horizontal keystone distortion.

23 2. Projecting an Image (Basic Operation) NOTE: • If the projection angle is the same as in the last use, the previous correction setting values are retained in the memory. • When doing Step 2, adjust the position of image so that the screen is smaller than the area of the projected area. • To reset the 3D Reform correction setting values, press and hold the GEOMETRIC. button for a minimum of 2 seconds. • Each time the GEOMETRIC. button is pressed, the item will change as follows: KEYSTONE → CORNERSTONE → None → KEY- STONE → ... For information on [CORNERSTONE], see “Correcting Horizontal and Vertical Keystone Distortion (Cornerstone)” on page 32. • The Cornerstone adjustment will not be available during the Keystone adjustment. To perform the Cornerstone adjustment, press and hold the GEOMETRIC. button for a minimum of 2 seconds to reset the Keystone correction setting values. The Keystone adjustment will not be available during the Cornerstone adjustment. To perform the Keystone adjustment, press and hold the GEOMETRIC. button for a minimum of 2 seconds to reset the Cornerstone correction setting values. • The 3D Reform feature can cause an image to be slightly blurred because the correction is made electronically. 5. Repeat steps 2 and 4 to correct keystone distortion. 6. After completing Keystone correction, press the EXIT button. The Keystone screen will disappear. • To perform Keystone correction again, press the GEOMETRIC. but- ton to display the Keystone screen and repeat above steps 1 to 6.
