Configure Lens Motor Trigger: CineWide 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 RS-900 for proper AutoScope operation:
1. Press MENU on the remote control.
2. Select Setup from the Main menu and press ENTER.
3. Use the number buttons on the remote to enter the Setup menu passcode when
prompted and press ENTER again. Then, press MENU on the remote control.
4. Select 12-volt Trigger from the Setup menu.
5. Set the 12-volt Trigger to "Cinema." This enables the lens motor to move the
anamorphic lens into position (in front of the primary lens) when the Cinema or Virtual
Cinema aspect ratio is selected.
6. Select the Cinema or Virtual Cinema aspect ratio to move the anamorphic lens into
position, if it isn't already. To do this, press CINEMA or VCINE on the RS-900
remote control (Figure 2-4).
