After the adjustment is complete, press the WRITE button.
The adjusted level is stored, and the display returns to the MANUAL
ADJUST menu.
Do not operate the controller for about 10 seconds after the WRITE
button is pressed, as the JumboTron display unit is writing the data into
the memory.
To restore the level before adjustment without storing the
adjusted data
Press the SPG button before pressing the WRITE button in step 14. The
luminance level of the display unit returns to that before adjustment. You
can also restore the luminance level before adjustment using the "Load:
User Data" mode described in "Displaying the Luminance Level before
Adjustment/Displaying the Factory preset Data/Storing the Currently
Displayed Data."
Before finishing the luminance adjustment, you can display the revised
data before starting the adjustment ("Load: User Data" mode) or display
the factory preset data even after changing the revised data ("Load:
Factory Data" mode). After displaying these revised data, you can store
them in the memory ("Save" mode).
The "Load: Factory Data" mode is available only for the following
versions of the JumboTron display unit:
LDU-3050 with serial number 1001758 and later numbers (program
ROM ver.1.2 and later versions)
LDU-G3050 with serial number 1000001 and later numbers (program
ROM ver.1.2 and later versions)
LDU-1540L with serial number 1016311 and later numbers (program
