T4 Universal System Controller
12
If the light sensor is enabled, there are two backlight levels to
adjust. Press the left arrow or right arrow buttons to adjust. Press
the OK button when finished.
With the light sensor enabled, the backlight brightness will
automatically change between the two levels, depending upon the
ambient lighting conditions.
Note: Non-zero values for the backlight level in Idle
mode can be entered, but will be ignored unless
the T4 is on the docking station. Also, the
maximum idle mode backlight setting is 30%
while on the docking station.
