Press the ENTER button.
The data of the selected mode appear in the display window. For
details, see the respective item below.

To check other modes or those for other units, press the ENTER button
again and repeat steps 2 to 4.
6
Press the UNIT CONTROL button to finish checking.
If the selected unit number does not exist or the
communication is not carried out correctly
The "Communication Error!" appears in the display window instead of the
data of the selected mode. Check the cause and try to repeat the steps
above.
To check the revised light emission data of each dot
The light emission data of each dot in a JumboTron display unit are
adjusted to light evenly. You can check the revised data of each dot in the
display window.
In step 2 on page 34, set "SCREEN No. (JTU-17, LDU-15 only)" and
"UNIT Address," then select one of the following modes.
JTU-35
PWM: The revised pulse width data of each dot for the selected position
are displayed.
G1V: The revised voltage data of each cell are displayed.
