Adjusting the Lens Position:

Installation

7.Select the Cinema aspect ratio to move the anamorphic lens into position, if it isn’t already. To do this, press CINEMA on the LS-10i remote control (refer to LS-10i Remote Control on page 9).

Adjusting the Lens Position:

1.Adjust the vertical position and tilt of the lens so that the projector beam is passing through the center of the lens and any residual pincushion distortion is about the same at the top and bottom of the image. This typically results in the anamorphic lens being below the center of the primary lens and tilted slightly downward.

2.Tighten the knobs.

There may be some pincushion distortion even after the lens is

Note properly adjusted, especially at shorter throw distances. If this is the case, Runco recommends that you slightly over-scan the image into the screen frame area to mask the distortion.

3.Adjust the rotation of the Lens Transport Assembly so that the left and right sides of the image are an equal distance from their respective screen borders.

4.Tighten the Pivot Screw and the four mounting screws holding the transport to the Attachment Plate.

5.For optimum multiple aspect ratio performance, adjust the projector’s zoom so that a 1.85:1 aspect ratio movie is just masked by the top and bottom of the screen border when the anamorphic lens is not in front of the primary lens. This way 1.85:1, 16:9 and 2.35-2.4:1 aspect ratio movies are all presented to fill the screen at a constant height.

6.Remove the protective film from the front of the anamorphic lens.
