Marantz manual Adjusting the LN-11S1A Lens

ADJUSTING THE LN-11S1A LENS

To adjust the LN-11S1A lens, an adjustment method that uses the remote controller included with a VP11 or VP15 series projector is described here. For details on the method of moving the anamorphic lens, refer to “BASIC OPERATION” on page 3.

1. Before starting LN-11S1A lens adjustment, projector installation and initial settings must be completely finished. Be sure to complete initial settings and adjustment of the projector itself, while referring to the projector’s user’s guide. Turn on the projector’s power and display the internally generated cross-hatch test pattern.

2. Aim the remote controller included with the VP11 or VP15 series projector at the remote control receiver of the lens slider and press the AUX1 button to move the anamorphic lens to the operating position. Check that the center of the LN-11S1A anamorphic lens in the horizontal direction is aligned with the center of the projector’s lens in the horizontal direction. If the centers are not aligned, adjust by turning the screws shown in the figure to the right in the direction of the arrow. Refer to Figure 27.

Figure 27

Note:

If the anamorphic lens and projector are not adjusted correctly, the test pattern being projected may be distorted.

You can easily align lens centers between your projector and LN-11S1A and adjust the tilt of LN-11S1A as well, if you mark a certain position at your screen as a guide to align.

Note:

When you mark the position, take care not to blemish your screen.

3. If the test pattern is distorted, adjust by loosening the screw on the side of the anamorphic lens so that the light being projected passes through the center of the anamorphic lens as much as possible. Refer to Figure 28.

Figure 28

Note:

Never look directly into the lens. Always confirm positioning from the side of the lens.

At the same time, adjust the tilt of the anamorphic lens so that the outer edges of the test pattern are straight. After adjusting the height and tilt of the anamorphic lens, securely tighten any loosened screws.

4. In order to take full advantage of the performance of the anamorphic lens, it is important to keep the gap between the anamorphic lens and projector’s lens is as small as possible. Adjust the gap between the anamorphic lens and projector’s lens by loosening the screw located on the lens slider. Refer to Figure 29. After adjustment, securely tighten the loosened screw.

5. This is the final adjustment. Using a Phillips-head screwdriver, adjust the focus of the anamorphic lens so that the test pattern appears as sharp as possible. Refer to Figure 30.
