CHAPTER 3 | OPERATION
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
nished.
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.
