Setup Display Brightness Configuration:
Step 6:
The sign automat ically controls the display brightness for optimal visibilit y under all
ambient light ing condit ions. The ambient light is sampled by a built in light sensor
located on the front face of the PCB or by an optional external light sensor wired to the
AUX connector. A control algorithm computes the optimal brightness and adjusts the
average LED current via a PWM circuit. PWM circuit is designed to prevent flicker and
color distortion.
You may chose to bias automat ic brightness control algorithm towards saving batt ery
(Battery Life Opt imized) or making the display brighter and hence more noticeable
(Brightness Optimized).
In the “Battery Life Optimized” setting the display brightness is reduced by about 30%
from the factory default sett ing for any ambient lighting condit ion. This can be
particularly advantageous for portable signs operating solely off a battery and allow the
sign to operate up to 30% longer under heavy traffic condit i ons. If you find the display
brightness in-adequate then set the display to “Brightness Optimized”.
Setup Operating Mode Configuration:
Step 7:
For normal operation of the sign on the road select “Normal Operat ion”. In this mode the
radar will pickup actual targets in front of the unit and display them on the digits if they
range between the Minimum Display Limit and Maximum Display Limit.
The sign also supports a “Demo Mode”. In this mode, the radar generates a pre-
programmed sequence of speeds and shows them on the display. Note that the speed
limits st ill apply to these speeds, so select ing different limits will change what speeds are
displayed and if the strobe is act ivated. The ambient l ight sensor and automatic display
