Installation 40 Vidikron Vision Model 120 Owner’s Operating Manual PREL IMINARY Connecting to AC PowerProjector/VHD Controller: Plug the female end of one power cord into the AC receptacle on the rear of the Vision 120 (AC 100V ~ 240V). Then, connect the other end to your AC power source. Similarly connect the VHD Controller to a nearby AC outlet. AutoScope Lens Motor: With AutoScope-equipped projectors, an additional power cord is provided for the lens motor. Plug the female end of the AC power cord into the AC input on the rear of the lens motor assembly. Connect the other end to a 110 VAC power source. 3.8 Turning on the Power 1. Turn on your source components. 2. Turn on the main power switch at the rear of the VHD Controller. 3. If this is an AutoScope-equipped projector, turn on the main power switch at the rear of the AutoScope lens motor. The lens motor power switch is located next to the AC input (see Figure 3-17). 4. Press the ON button on the remote control – or the SOFT PWR button on the VHD Controller front panel – to turn on the system. The vacuum fluorescent display on the VHD Controller front panel briefly displays “Starting Display.” 5. When the projector is ready for use (after about 20 seconds), the RUN LED on the VHD Controller front panel lights solid blue. The fluorescent display indicates the current input source, aspect ratio and input resolution; for example: 3.9 Adjusting the Picture Orientation By default, the Vision 120 is configured for a “floor/front” installation, in which the projector is installed upright and in front of the screen. If it is installed behind the screen and/or inverted, you must change the picture orientation. To do this: 1. Press MENU. 2. Select Service from the Main Menu and enter the Service Menu passcode. 3. Select Display Device from the Service Menu. 4. Select Installation from the Display Device menu. 5. Choose Floor Rear, Ceiling Front or Ceiling Rear, to match the installation method. ➤ The input voltage to the AutoScope lens motor must be between 100 and 120 VAC. Do not connect the AutoScope lens motor to a 200-240 VAC power source!Caution V120 Component RCA 16:9 480I Current Input Source Aspect RatioInput Resolution

Alternatively, select Display Device from the Service Menu. Select Configure, then Lens from the Display Device menu. The Lens menu gives you a great deal of control over the picture size, position and focus: FocusTo focus the projected image, use the cursor buttons to highlight “In” or “Out.” Then, press and hold the ENTER button on the remote control. ZoomTo make the picture smaller (zoom out), use the cursor buttons to highlight the minus sign (-). Then, press and hold the ENTER button on the remote control. To enlarge the picture (zoom in), use the cursor buttons to highlight the plus sign (+). Then, press and hold the ENTER button on the remote control. Vertical and Horizontal Lens Shift To change the projected image position, use the cursor buttons to highlight “Left,” “Right,” “Up” or “Down” in the Lens menu. Then, press and hold the ENTER button to shift the image in that direction. You must enter a passcode to access the Service menu. Note

Attach Lens Mounting Assembly to Lens Motor Carriage Plate (CineWide with AutoScope) or Base Plate (fixed CineWide) The Vision 120 Anamorphic lens mount kit consists of everything shown in Figure 3-19. Some components shipped with your projector may differ slightly from what is shown in these instructions. If any items are missing or damaged, please contact your Vidikron dealer or Vidikron Customer Service at (888) 4VIDIKRON. Figure 3-19. Vision 120 Anamorphic Lens Mounting Assembly - Exploded View 1. Remove the two Yaw/X Adjustment Levers (item #8) from the bottom of the Anamorphic Lens Holder (item #5). 2. Place the Anamorphic Lens Holder on top of the AutoScope Carriage Plate or fixed CineWide Base Plate (item #7). Position the bracket so that the long slot at the bottom of the lens holder is perpendicular to the corresponding slots on the plate. It is extremely important that the primary lens is properly adjusted before you install the anamorphic lens. Ensure that the image from the primary lens is perfectly centered on the screen.

Secure the Anamorphic Lens Holder to the plate using the Hex Bolts/Washers (item #6) and Yaw/X Adjustment Levers that you removed in Step 1. 4. Use the Lens Mounting Screws to attach the Lens Adapter Ring (item #1) to the Pitch Adjustment Yoke (item #2); see Figure 3-20. (Use the round, threaded holes on the yoke.) 5. Use the Height/Y Adjustment T-Screws (item #3), Pitch Adjustment T-Screws (item #4) and T-Nuts (item #9) to attach the Pitch Adjustment Yoke and Lens Adapter Ring to the Anamorphic Lens Holder. The Yoke should be as close to the primary lens as possible. 6. Attach the lens to the Lens Adapter Ring by threading it clockwise. Figure 3-20.

Installation 44 Vidikron Vision Model 120 Owner’s Operating Manual PREL IMINARY Configure Lens Motor TriggerCineWide with AutoScope maintains constant image height independent of the aspect ratio, while using the full display resolution of the projector. It accomplishes this by moving the anamorphic lens in front of the primary lens when widescreen material is being viewed. When the viewer transitions back to 16:9 or 4:3 source material, the anamorphic lens moves out of the light path. To configure the lens motor trigger on the VHD Controller for proper AutoScope operation: 1. Project a 2.35:1 aspect ratio test pattern or other image on the screen. 2. Press MENU on the remote control and enter the Service menu passcode. 3. Select Service from the Main menu. 4. Select Triggers from the Service menu. 5. Assign the trigger output to which the lens motor is connected to the Cinema and IntelliWide 2.35 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. To save the trigger settings, press repeatedly to highlight “Save.” Then, press ENTER. 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 VHD Controller remote control ( Figure 2-5), or press or repeatedly with no menus visible on-screen. Adjust the Anamorphic LensAdjusting the Horizontal (X) Lens Position: 1. Project a white field on the screen. 2. Loosen the Yaw/X-Adjustment Levers underneath the lens. 3. Slowly move the anamorphic lens into place so that there are no shadows on either side of the screen: 4. When the horizontal position is properly set, tighten the Yaw/X-Adjustment Levers to secure the lens in place. ➤ ➤ Too Far RightToo Far Left Correct position
Installation Vidikron Vision Model 120 Owner’s Operating Manual 45 PREL IMINARY Adjusting the Height (Y): With the white field still on-screen, loosen the Height/Y Adjustment T-Screws on either side of the lens. Then, slowly move the anamorphic lens into place so that there are no shadows on the top or bottom of the screen: When the height is properly set, tighten the Height Adjustment T-Screws to secure the lens in place. Pitch (Angle): Next, angle the lens to even out any top-to-bottom pincushion distortion. To do this, loosen the Pitch Adjustment T-Screws (directly below the Height/Y Adjustment T-Screws) on either side of the lens to allow it to pivot freely. Then, adjust the anamorphic lens angle so that the projected image is rectangular: The anamorphic lens will almost always be angled with respect to the projector; this is normal. Once the proper lens angle has been set, firmly tighten the Pitch Adjustment T-Screws to secure the lens in place. There may be some pincushion distortion even after the lens is properly adjusted, especially at shorter throw distances. If this is the case, Vidikron recommends that you slightly over-scan the image into the screen frame area to mask the distortion.

Installation Vidikron Vision Model 120 Owner’s Operating Manual 47 PREL IMINARY Adjusting the Geometry: 1. Input an anamorphic cross-hatch test pattern to the projector. 2. Unscrew the Anamorphic Lens just enough to allow it to rotate freely. 3. Grasp the lens by the center ring and rotate the lens until the image is properly anamorphic: 4. When the image geometry appears correct, tighten the Anamorphic Lens Set Screw (item #10) to secure the lens in place. (When viewed from the front, the rear opening on the anamorphic lens should appear as a tall, narrow oval.) Focus: Finally, rotate the Focus Ring on the anamorphic lens to fine-tune the optical focus. Wrong Position Correct Position FOCUS
