Dimming
The dimming level of the Rate display can be adjusted in two ways. A light sensor,
mounted on each driver, can detect the level of ambient light at the display location
and dim the sign's LEDs accordingly. This function is known as automatic dimming.
When the manual dimming function is selected, the LEDs remain at the same level
of brightness regardless of the level of light detected at the display.
To select either of these functions, press <
DIMMING >. The current setting is shown
on the bottom line of the LCD.
