Low Power
NOTE: Low Power Mode and the optional AutoDim feature are disabled when the light
bar is in MODE 3 or displaying the Intersection flash pattern.
LOW LIGHT HAZARD: Enabling the Low Power function in the light bar may cause
the light output to fall below certain current light output standards and guidelines
for emergency warning lights. Use extreme caution when using this function.
Ensure that the ambient light conditions are low enough that you are seen and
that the reduction of glare from the light bar is safer than full light output in the
situation. Failure to heed this warning may result in serious injury or death to you
or others in your vicinity.
When Low Power is selected, the LEDs are dimmed to approximately 50 percent of their
full brightness. Low Power is only functional in MODE 1 or MODE 2. Low Power is disabled
when switching to another flash pattern, including Intersection. To use Low Power again,
disconnect Low Power reapply Low Power after a change in flash pattern occurs.
