3.
Select Service from the Main Menu and enter the Service Menu passcode.
4.
Select Triggers from the Service menu.
5.
Assign the trigger output to which the lens motor is connected to the Cinema and
Virtual Cinema aspect ratios. This enables the lens motor to move the anamorphic
lens into position (in front of the primary lens) when either aspect ratio is selected.
6.
Select the Cinema aspect ratio to move the anamorphic lens into position, if it isn’t
already. To do this, press CINEMA on the DHD Controller remote control (Figure 2-6),
or press
or
repeatedly with no menus visible on-screen.
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.
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.
You must enter a passcode to access the Service menu for the first
time after turning on the system.
There may be some pincushion distortion even after the lens is
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.
