Adjusting the Picture
Orientation
By default, the RS-900/RS1100 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 mounted on a ceiling, you must change the picture orientation. To do this:
1. Press MENU on the remote control.
2. Select Installation from the Main Menu and press ENTER.
3. Select Orientation from the Installation Menu.
4. Choose Floor Rear, Ceiling Front or Ceiling Rear to match the installation method.

Installing and
Adjusting the
CineWide Anamorphic
Lens
If you are installing a CineWide-equipped projector, proceed as follows to install and
adjust the anamorphic lens.
Runco offers two types of anamorphic lenses for its CineWide projectors: prismatic and
cylindrical.
• The prismatic lens compresses the height of the image (as opposed to stretching the
width) to achieve a 2.35:1 aspect ratio with a 1.78:1 display device.
• The cylindrical anamorphic lens has a larger aperture than the prismatic lens. It
stretches the width of the image to achieve a 2.35:1 aspect ratio with a 1.78:1 display
device. Two, cylindrical anamorphic lens options are available: Rainier II and McKinley.
Although they differ in size and throw distance range (refer to
Table 3-3), the installation
procedure for both lenses is similar.
The following models are available with either a prismatic or a cylindrical anamorphic lens:
• RS-900/CineWide
• RS1100/CineWide
• RS1100 Ultra/CineWide
The following models always use a cylindrical lens:
• RS-900/CineWide with AutoScope
• RS1100/CineWide with AutoScope
• RS1100 Ultra/CineWide with AutoScope
If you are installing a CineWide projector with a prismatic lens, refer to Whitney
(Prismatic) Anamorphic Lens Installation and Adjustment on page 45. If you are
installing a CineWide projector with a cylindrical lens, continue with the next section.
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.
