This button displays a window that allows you to adjust the backlight
brightness and enable/disable the Ambient Light Sensor.
If the light sensor is disabled, there is only one backlight level to adjust.
Press the left arrow or right arrow buttons to adjust. Press the OK button
when finished.
With the light sensor disabled,
the backlight brightness will
always stay at the same level
whenever the RK-V is turned-
on. The backlight level can,
however, be set differently
for the unit’s Normal and Idle
modes.
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. Also, the
backlight level can be set differently
for the unit’s Normal and Idle modes.
