JTC-C200 ICU controller

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

Adjustments of the images on the screen

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.
