personnel only.
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-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).
JTC-P200 ICU
The ICU (Image Control Unit) is the main unit for controlling the images
on the JumboTron screen. Connect the image sources to the ICU, and
control with the JTC-C200 ICU controller and JME-SA200 screen
alignment controller.
For details, refer to the Operation Manual of the JTC -C200 ICU
controller.
JTA-LS200 ABC Sensor Unit
The ABC (Automatic Brightness Control) sensor unit is used for the
automatic adjustment of the brightness of the screen. Connect the ABC
sensor unit to the JTC-P200 ICU to detect the ambient light.
For details, refer to the Operation Manual of the JTC-C200 ICU controller.
