Display Operation
Dimming
The dimming level of the rate display can be adjusted in two ways. A
temperature/light sensor, mounted near the display, 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.
