Overscan: Image Overscan pushes the outside edge of the active picture area of the 
video signal out beyond the edge of the display area. 
Some television programs are produced based on the assumption that older television 
sets may not display the outer edges of the broadcast picture area. Over scan effectively 
trims away these inactive, outer edges and enlarges the remaining portion of the image to 
fill the display area.
Select from 1% to 10% of Overscan, as desired.
For HDTV, DVDs and other video sources, Overscan is generally not necessary or 
desirable.
ISF PresetsFor each input, the SC-1 lets you save image quality settings as presets that you can 
recall at a later time. You can create up to four presets per input and resolution. Use the 
ISF Presets menu to recall saved image presets, or to save image settings in the 
“Custom
 1” or “Custom 2” memory location. The currently-selected preset is indicated by 
a “
7” to its left; in the example shown here, ISF Night is selected.
You should save changes to any of the following settings to a preset; otherwise they will 
be lost when a new input source or resolution is selected:
 Brightness

 Color saturation

 Sharpness
To reset the Custom 1 and Custom 2 image presets to their factory defaults, select 
Factory Default and press ENTER.

CalibrationUse the Calibration menu to perform advanced picture quality adjustments. This menu 
should be used by ISF-certified technicians only. 
To recall the ISF Night or ISF Day settings, select “ISF Night” or “ISF Day” from the ISF 
Presets menu (see above). 
ISF Night - Display Color: Use the Display Color settings to adjust the projector lamp 
intensity. These settings are saved independently for each input.
Select Lamp Power from the Display Color Menu to adjust the lamp 
output level. You can choose to run the lamp as bright as possible (“100”), at its lowest 
power level (“0”) or choose a setting in between. Generally, lower lamp output prolongs 
the life of the lamp, but decreases brightness. 
 Lamp Intensity: Select Lamp Intensity from the Display Color Menu to adjust the lamp 
intensity level. Refer to 
Intensity on page 67. 
ISF Night - Input Image: The Input Image controls are similar to those in the Picture 
menu, but are accessible only by entering the Calibration menu passcode. This makes it 
possible to restore the picture quality settings to what they were when the projector was 
installed, simply by recalling the “ISF Night” preset. 
ISF Night - Input Color: Use the Input Color controls to adjust the color balance of the 
incoming signal. These settings are also saved independently for each input. 
Gain: Use the Gain controls to correct color imbalances in the bright areas of the 
image. A good way to do this is to use a test pattern consisting mostly of solid white 
areas, such as an 80 IRE “window” pattern. If the white areas contain traces of red, 
green or blue, decrease the Gain for that color.
set: Use the Offset controls in the White Balance sub-menu to correct color 
imbalances in the dark areas of the image. A good way to do this is to use a test 
pattern consisting mostly of dark gray areas, such as a 30 IRE “window” pattern. If the 
gray areas contain traces of red, green or blue, decrease the Offset for that color.
 Chroma Delay: Use the Chroma Delay control to correct a mis-aligned image from a 
Composite, S-Video or Component video source. Chroma delay in an image causes 
color shifts to occur to the left of the vertical edge transitions, producing artificial 
shadows or a “halo” effect. If necessary, adjust this setting to eliminate them. 
se: Adjust the phase if the image (usually from an RGB source) shows shimmer or 
“noise.” Pixel phase adjusts the phase of the pixel sampling clock relative to the 
incoming signal. The effect of this control is similar to that of a tracking control on a 
VCR. 
For best results, use a good test pattern such as a smooth gray consisting of a clear 
pattern of black and white pixels, or a similar “half on, half off” graphic image. (You may 
notice that you can stabilize the image at more than one point. Use either setting in this 
case.)

after a System Reset (described on 
page 85), press  repeatedly to highlight “Save.” 
Then, press ENTER. 
Splash Configure: Use the Splash Configure menu to customize the appearance of the 
start-up message that appears on the vacuum fluorescent display upon power-up. 
Owner Name/ISF Calibrated/ISF Other: You can have the SC-1 display the owner’s 
name, your name, the phrase “ISF Calibrated” and/or any other string, up to 20 
characters in length. 
Use the up or down cursor button to select a character. Use the right and left cursor 
buttons to change the cursor position. Press MENU when you have finished entering 
text. Then, check the “Splash Enable” box to have the SC-1 display the information you 
enter here when it is turned on. 
Runco/ISF Logo Splash Screen Timers: When you turn on the SC-1, it projects a 
welcome screen with the Runco logo followed by one with the ISF logo. Select Splash

from the DHD Controller remote control (
Figure 2-6) in ways that are unpredictable or 
undesirable. 
 You have multiple DHD Controllers and want to control them independently, as 
opposed to broadcasting commands from a single remote to all of them. In this 
scenario, you can use multiple remotes programmed to use different IR codes. Or, you 
can use a single remote and change the IR code as needed to address a specific 
device.

Auto Setup: Refer to Auto Setup on page 59. 
HD Format: If the characteristics of the incoming signal on the HD1 or HD2 inputs are 
known, select HD Format from the Service menu and set them as described below. Doing 
so can reduce the time it takes the DHD Controller to switch from HD to 480i signals or 
vice versa. 
This is generally not necessary unless the DHD Controller – for whatever reason – has 
difficulty determining the color space (RGB or YUV), bandwidth or resolution of the 
incoming HD signal. In most situations, the Auto settings work well.

You can assign one or more trigger outputs to each aspect ratio. Those triggers are then 
activated by selecting that aspect ratio. 
If your projector is equipped with the Runco CineWide with AutoScope system, assign at 
least one trigger output (the same one to which the lens motor is connected) to the 
Cinema and Virtual Cinema aspect ratios.
To save the trigger settings so that they can be restored after a System Reset (described 
below), press 
 repeatedly to highlight “Save.” Then, press ENTER. 
Miscellaneous: Select Miscellaneous from the Service menu to set the following options: 
 Language: Select Language from the Miscellaneous menu and press the up- or 
down-arrows to select the OSD language. (Currently, only English is supported.) 
This is the manner in which the OSD menus appear and disappear when 
you press MENU. Choose one of the following: 
0 = No transition; menus abruptly appear and disappear.  
1 = Menus fade in and out.  
2 = “Checkerboard” dissolve; menus appear and disappear in sections.  
3 = “Window shade” effect; menus are drawn on a diagonal from top left to bottom 
right, and retract in the opposite direction. 
Short/Long: These settings control how long the OSD menus stay on 
screen. Select a time-out period of from 2 to 60 seconds. 
Side Bar Color: This controls the color of the inactive image area. The range is from 
-100 (black) to 100 (white). 
 
 
The inactive image area is on either side of the active image area when using the

5.1 
Safety Guidelines
The SC-1 is designed for safe and reliable operation. However, safe operation is not 
assured by design alone; installers, service technicians, trained operators and all other 
users must maintain a safe environment at all times. Please read and understand all 
warnings and precautions in this manual and on the projector itself before attempting to 
operate or service the projector. 
AC/Power Precautions Do not attempt operation if the AC supply is not within the specified voltage range. 
 Do not allow anything to rest on the power cords. Locate the projector where cords 
cannot be damaged by persons walking on it or objects rolling over it. Never operate 
the projector if a power cable appears damaged in any way. 
 Do not overload power outlets and extension cords as this can result in fire or shock 
hazards. 
 Note that only qualified service technicians should open any enclosure on the 
product, and only if AC has been fully disconnected from the projection head and 
ballast. 
 Disconnect the SC-1 from AC before opening any enclosure. 
5. Maintenance and Troubleshooting
Never look directly into the projector lens or at the lamp. The 
extremely high brightness can cause permanent eye damage. 
For protection from ultraviolet radiation, keep all projector housings 
intact during operation. Protective clothing and safety goggles are 
recommended. 
The American Conference of Governmental Industrial Hygienists 
(ACGIH) recommends occupational UV exposure for an eight-hour 
day to be less than 0.1 microwatts per square centimeter of 
effective UV radiation. An evaluation of the installation site is 
advised to ensure that no one is exposed to cumulative radiation 
levels exceeding the government guidelines for your area. 
Be aware that some medications are known to increase one’s 
sensitivity to UV radiation. 
 
FIRE HAZARD. Keep hands, clothes and all combustible material at 
least one meter away from the concentrated light beam of the 
lamp. 
Position all cables where they cannot contact hot surfaces or be 
pulled or tripped over. 
Opening or removing a projector cover requires a qualified service 
technician.

5.2 
Maintaining Proper 
Cooling
The high-intensity lamp and electronics rely on a variety of cooling components to reduce 
internal operating temperatures. Regular checking and maintenance of the entire cooling 
system is critical to prevent overheating and sudden projector failure, and helps to ensure 
reliable operation of all projector components over time. 
Ventilation Vents and louvers in the projector covers provide ventilation, both for intake 
and exhaust. Never block or cover these openings. Do not install the projector 
near a radiator or heat register, or within an enclosure. 
 
Air Filter It is recommended that you replace the air filter (located on the lamp side of the projection 
head) whenever you replace the lamp, or more often in dusty or dirty environments. A 
clogged filter reduces air flow, and can lead to overheating and projector failure. Check 
the air filter monthly. For detailed instructions, refer to 
Lamp and Filter Replacement on 
page 91. It is also recommended that you visually check the laminar airflow device (LAD) 
located nearby. The LAD should be nearly white or light grey in color. 
Liquid Cooler The liquid cooler system circulates liquid to and from the DMDs in the projection head, 
reducing their operating temperature to an acceptable level. Periodically check the coolant 
level visible by removing the igniter grille (rear side grille adjacent to the side input panel). 
The reservoir should be approximately half-full. 
FILLING THE COOLER: The cooler should require filling only upon projector installation. 
Fill with a 50/50 mix of distilled water and ethylene glycol. Top off as necessary. Do not 
overfill. 
Exhaust Duct and Lamp 
Fan Interlocks
After installation, check and maintain operation of both vane switches — one in the 
exhaust duct and one near the lamp fan — as follows: 
1. Turn the projector on (lamp is not needed). 
2. Turn your extractor fan OFF. 
3. Confirm that the LCD status display shows that the extractor fan vane switch has 
failed. Turn fan back ON to correct. 
4. Block the air intake at the rear corner of the projection head (input side, next to the 
ballast control and safety interlock connectors; see 
Figure 2-1). 
5. Confirm that the LCD status display shows that the lamp fan vane switch has failed. 
Clear air intake to correct. 
6. Repeat this procedure every six months in permanent installations. 
Maintain vane switches as described in the next section, Maintenance and Cleaning. 
➤
➤
➤
A failure of the liquid cooling system will trigger an over-temperature 
alarm condition, clearly indicated with status displays at the top of 
the projector. 
Whenever coolant has been added or replaced, check for a 
possible airlock upon the next projector power-up.
