For the customers in the U.S.A.
This equipment has been tested and found to comply with
the limits for a Class A digital device, pursuant to Part 15 of
the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when the
equipment is operated in a commercial environment. This
equipment generates, uses, and can radiate radio frequency
energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio
communications. Operation of this equipment in a residential
area is likely to cause harmful interference in which case the
user will be required to correct the interference at his own
expense.
For JTC-C200 and JTC-P200
Attention – when the product is installed
in a rack:
• Elevated operating ambient temperature
If installed in a closed or multi-unit rack assembly, the
operating ambient temperature of the rack environment
may be greater than room ambient.
Therefore, consideration should be given to installing
the equipment in an environment compatible with the
manufacturer’s maximum rated ambient temperature of
0 to 45°C (Tmra).
• Reduced air flow
Installation of the equipment in a rack should be such
that the amount of air flow required for safe operation of
the equipment is not compromised.
• Mechanical loading
Mounting of the equipment in the rack should be such
that a hazardous condition is not achieved due to
uneven mechanical loading.
• Circuit overloading
Consideration should be given to the connection of the
equipment to the supply circuit and the effect that
overloading of circuits might have on overcurrent
protection and supply wiring.
Appropriate consideration of equipment nameplate
ratings should be used when addressing this concern.
• Reliable earthing
Reliable earthing of rack-mounted equipment should be
maintained. Particular attention should be given to
supply connections other than direct connections to the
branch circuit (e.g., use of power strips).
Owner’s Record
The model and serial numbers are located on the rear.
Record these numbers in the spaces provided below.
Refer to them whenever you call upon your Sony dealer
regarding this product.
Model No. ______________ Serial No. _______________
WARNING
To prevent fire or shock hazard, do not
expose the unit to rain or moisture.
To avoid electrical shock, do not open the
cabinet. Refer servicing to qualified
personnel only.

AboutThis Manual
This instruction manual is aimed at the ICU operator and it explains how
to display the images on the JumboTron screen using the JTC-P200 ICU
(Image Control Unit) and the JTC-C200 ICU controller of the JumboTron
system.
The operator is also required to have knowledge of image output
equipment, such as VCRs, video cameras and computers. For the
operation of these pieces of equipment, refer to their operation manuals.
For the maintenance and adjustment of the JumboTron System, consult
with qualified Sony service personnel.
Precautions
On safety
•Do not forcibly bend the power cord. Do not place or drop any heavy
object on it. If the power cord has been damaged, a fire or electric shock
hazard may occur.
•To disconnect the power cord, pull it out by the plug. Never pull the cord
itself.
•Do not use a damaged power cord.
•Do not drop any liquid or solid object into the cabinet.
•Do not open the cabinet.
•Do not use or leave the unit at extremely high or low temperatures.
•Do not use or leave the unit in high humidity.
On cleaning
•Clean the case and front panel with a dry soft cloth, or a soft cloth
slightly moistened with a mild detergent solution. Do not use any organic
solvents, such as alcohol or benzine which might damage the finish.
•Be sure to unplug the unit before cleaning.
Overview
Table of Contents 5
The JumboTron system displays video images on a large screen
(JumboTron screen) located either outdoors or indoors. Images from video
sources such as a VCR, video camera and computer can be displayed on
the screen.
The JumboTron system provides superb bright images with high
resolution, regardless of whether it is day or night, indoors or outdoors.
Images to be displayed on the JumboTron screen
The JumboTron system can display the following three types of images:
[a] Video images input from equipment such as a VCR, video camera
and video disc (INPUT 1)
[b] Computer graphics (INPUT 2)
[c] Mixed images of INPUT 1 and INPUT 2
(INPUT 1 images are superimposed on the monochrome area of the
INPUT 2 images.)

6 Overview
Structure of the JumboTron screen
Two types of the JumboTron screen are available. One is the conventional
CRT type screen in which light emitting bodies of three primary colors (R,
G and B), “Trinilite,” are used as the light emitting element. The other is
the new LED type screen in which light emitting diodes of the three
primary colors are used.
The basic element of the JumboTron screen is an RGB trio (dot).
A “cell” consists of the dots arranged at a certain interval (picture element
pitch) and a “unit (JumboTron display unit)” consists of 12 cells for the
CRT type and 16 cells for the LED type.
There are three unit types, the JTU-35 series (with 35-mm picture element
pitch) and JTU-17 series (with 17.5-mm pitch) of the CRT type, and the
LDU-15 series (with 15-mm pitch) of the LED type. You can configure a
large JumboTron screen by arranging the JumboTron display units
vertically and horizontally to suit various uses or locations.

Features
JTC-C200 ICU controller
The JTC-C200 ICU controller is the remote controller for the JTC-P200
ICU (Image Control Unit) which controls the images on the JumboTron
screen. Using the ICU controller, you can control the ICU from a control
room at a distance of up to 500 m (1640 feet). The main functions of the
JTC-C200 are as follows:
Turning on/off the ICU and screen
You can turn the ICU and the JumboTron screen on and off.
Selection of screen display mode
You can select the images to be displayed on the JumboTron screen from
among three modes: INPUT 1 (video images), INPUT 2 (computer
graphics) and MIX (mixed images).
Adjustments of the images on the screen
You can adjust the brightness, hue, color and sharpness of the images on
the screen.
The brightness can be automatically adjusted according to the ambient
light with the JTA-LS200 ABC sensor unit. You can also set the desired
brightness level manually, and four brightness levels can be stored in the
memory and recalled at a touch.
JTC-P200 ICU (Image Control Unit)
The JTC-P200 controls the images on the JumboTron screen.
JTA-LS200 ABC sensor unit
The JTA-LS200 ABC (Automatic Brightness Control) sensor unit
connected to the ICU senses the ambient light for the automatic brightness
control.
