IMPORTANT THEATER GUIDANCE
- Projection screen should be flat, in the 2.4:1 aspect ratio and with a minimum 2.0” screen border.
- Projector lens center should be between -4 and +18 inches from the top edge of the screen surface (about +3 to +5 inches is ideal) and horizontally centered on the screen +/- 3 inches.
- Throw ratio (projector throw distance divided by screen surface width) should be at least 1.45:1.
- Longer throw distances are encouraged to reduce edge distortion. About 1.5” of screen border is needed to mask the edge at a 1.45:1 throw ratio. About 1.0” is needed at 1.6:1. At a 2.0:1 throw ratio distortion is very difficult to see in any content.
Installation Steps
-
INSTALL THE LENS RETAINER.
Remove the two front assembly screws and remove the retainer. Adjust the projector lens shift to vertically and horizontally center the projector lens. Squeeze the retainer and work it into the projector opening to nest into the inside rim of the projector housing as shown with prongs toward the ceiling and the bottom ridge aligned with the projector bottom-front rib. Tighten the two retainer screws just enough to lock.
-
PREPARE THE PROJECTOR.
Adjust the projector roll, tilt and/or yaw so the projector test pattern lines are square to the screen edges. Adjust the vertical lens shift so the test pattern is centered on the screen. Now show a 2.4:1 movie instead of the test pattern. Set the Sony anamorphic lens menu setting to 1.32x and set the Sony Aspect button on the remote to V-Stretch. -
INSTALL THE CDR LENS.
After removing the rear CDR lens cover, install the CDR lens/mount assembly over the retainer prongs. Insert and tighten the two assembly screws to secure (do not over tighten). Remove the front protective film.
-
ADJUST THE LENS TILT AND PROJECTOR SHIFT.
Adjust the projector lens zoom to fill the width of the screen with the 2.4:1 movie. Tilt the CDR lens and adjust the projector vertical lens shift to make sure the beam is getting through the CDR lens to fill the screen. There is only a slight variation in vertical image height with this adjustment but experimentation may lead to the best image fit and geometry. Lock the CDR lens tilt by tightening the single Phillips tilt lock screw (do not over tighten). -
DECIDE HOW TO WATCH 16:9 CONTENT
(including menus). Use the Sony “Aspect” button on the remote to select Squeeze to watch 16:9 content in the center of the screen or select Normal to stretch 16:9 content to fill the entire screen width.
CLEANING.
Small amounts of dust and wipe marks are very noticeable on lens surfaces with a high brightness projection beam but typically will not impact the image as much as damage from excessive cleaning in pursuit of a “perfect” optical surface. Occasionally blowing off the lens surfaces with clean air is the best way to maintain long term performance. If there is any excessive residue or build-up then it is recommended that you clean the optics with professional lens cleaning supplies such as from a camera store while the lens is in front of the lit beam of the projector. This will allow you to quickly see if the cleaning process is causing any damage.
