2.4.1 Blank Display
If the display on the T72XW terminal appears to be blank, first confirm if the display is actually
blank or if the backlight is simply off or if the contrast adjustment is incorrect. Even with the
backlight off or a poor contrast setting, changing weight digits should still be barely visible with a
change in weight.
