This feature sets the brightness of the illumination by altering LED power. The default
is 10, which is maximum LED brightness. For values from 1 to 10, LED brightness
varies from lowest to highest level of brightness.

scanning performance will also be reduced. It is recommended that you use a
brightness level above level 2.
