Vertical and Horizontal 
Lens Shift
If it is not possible to align the projector and screen as shown in Figure 3-3, you can use 
the lens shift controls to center the image on the screen. Lens shift is generally expressed 
as a percentage of the screen height or width, as shown in 
Figure 3-4 and Figure 3-5.

Table 3-4 gives the lens shift limits for the RS-440, as percentages and absolute 
measurements with a 96 x 54 inch (1.78:1) screen. 
Folded OpticsIn rear-screen applications where space behind the projector is limited, a mirror may be 
used to fold the optical path, as shown in 
Figure 3-6. The position of the projector and 
mirror must be accurately set. If you are considering this type of installation, contact your 
dealer for assistance.

Notes: 
1. With no vertical or horizontal lens shift, the lens center and screen center are aligned with each 
other.
2. Vertical shift limits are percentages of the screen height. Horizontal shift limits are percentages of 
the screen width.
3. Vertical lens shift figures apply to ceiling mount configurations. For floor installations 
(where the projector is upright), reverse the up/down vertical offset percentages.

Other ConsiderationsOther considerations and tips that can help improve your installation:
 Keep the ambient temperature constant and below 35°C (95°F). Keep the projector 
away from heating and/or air conditioning vents. Changes in temperature may cause 
drifts in the projector circuitry, which may affect performance.
 Keep the projector away from devices that radiate electromagnetic energy such as 
motors and transformers. Common sources of these include slide projectors, 
speakers, power amplifiers and elevators.

Installing the Optional 
CineWide Lens Base 
Plate
If you are installing an RS-440LT/CineWide, proceed as follows to install the CineWide 
anamorphic lens base plate. Otherwise, skip this step and proceed with 
Mounting the 
RS-440 (page 22). 
To install the fixed CineWide base plate on an RS-440LT/CineWide:
1. Place the projector upside down on a blanket or other soft surface.
2. Line up the three mounting holes on the CineWide base plate with those on the 
bottom of the projector.
3.If you are mounting the RS-440LT/CineWide on a ceiling: Line up the three holes 
on the projector ceiling mounting plate (included with the projector ceiling mount kit) 
with those on the bottom of the projector.
4. Secure the CineWide base plate (and ceiling mounting plate, if needed) to the 
projector with the M4x14mm screws provided with the CineWide lens base plate. See 
Figure 3-7.  
➤
1. Do not install the CineWide lens yet, only the fixed CineWide 
base plate. You will install the CineWide lens after you install the 
projector and adjust the primary lens. 
2. Some components shipped with your projector may differ slightly 
from what is shown in these instructions.
1. Do not use the mounting screws provided with the ceiling 
mount kit. Use only the hardware provided with the CineWide 
lens base plate.
2. DO NOT OVER-TIGHTEN THE SCREWS.

Mounting the RS-440
There are several methods for mounting the projector. Depending on your chosen 
installation, one method may be more suitable than another. 
Floor Mounting (Upright)In typical front and rear screen installations, the projector can be mounted to a secure and 
level surface such as a table or cart. Carts are useful when moving a projector during a 
presentation or from site to site. If possible, lock the wheels when it’s in position to prevent 
it from being moved during a presentation.
Ceiling Mounting 
(Inverted)
For fixed installations, and for those that want the projector out of sight or have a limited 
space for projector and audience, you can invert the RS-440 and suspend it from the 
ceiling using a specially-designed ceiling mount fixture. 
 
The projector can also be inverted and placed in an enclosure above and behind the 
viewing area. Install four feet on the inside bottom surface of the enclosure on which the 
projector can rest. A variety of materials can be used for this purpose (for example, rubber 
crutch tips or turntable feet).
Adjusting the Projector 
Height or Projection Angle
When the RS-440 is installed upright, you can adjust the projector height or projection 
angle by turning the four adjustable feet on the bottom of the projector; see 
Figure 3-8. 
This is useful for correcting the angle of projection when the projector is placed on an 
uneven surface or when the screen is at an angle. You can tilt the projector up to five (5) 
degrees up or down by adjusting the feet.
The feet are connected to threaded bolts; turn them clockwise to raise the projector or 
counterclockwise to lower it.
 
Figure 3-8. Adjusting the Feet
➤
➤
Use only the Runco-approved ceiling mount kit designed for your 
projector. Install the mount kit according to the instructions 
provided with it. Note
➤
Tilting the projector may cause keystone distortion. To correct this, 
refer to

Connections to the 
RS-440
Proceed as follows to connect the RS-440 to your video sources, external controller(s) – if 
present – and AC power.
When connecting your equipment:
 Turn off all equipment before making any connections.
 Use the correct signal cables for each source.
 Ensure that the cables are securely connected. Tighten the thumbscrews on 
connectors that have them.
Connector Panel AccessTo access the connector panel, pull firmly on the cable access cover to open it.
Connecting Source 
Components to the 
RS-440
Connect your video sources to the RS-440 as shown and described in the sections that 
follow.
HDMI/DVI Connections: See Figure 3-9.
Use the HDMI input whenever possible. This ensures the highest 
video quality because the signal is carried in the digital domain 
throughout the entire signal path, from source component output 
into the projector.

1. Refer to Computer Signal Compatibility on page 67 for a list of 
computer signals compatible with the RS-440. Use with signals 
other than those listed may cause some functions not to work.
2. Some Macintosh computers may require a Macintosh video 
adapter. Contact your nearest authorized service center or dealer.
3. This RS-440 may not be able to display images from notebook 
computers in simultaneous (CRT/LCD) mode. Should this occur, 
switch the notebook computer to “CRT only” mode. If you are 
unsure how to do this, refer to your notebook computer’s user 
manual.
