2. Front panel LED and switch
(1) POWER：POWER RED LED→On= Power applied to detector.；Off = No power or fuse is
bad.
(2) DETECT：DETECT GREEN LED→On = Vehicle being detected；Blinking = Loop Failure.
(3) SWITCH 1(SENSITIVITY)：Selections of sensitivity are from 0 to 9 and A to F where 0
stands for the lowest sensitive and F is the highest sensitive.

FUNCTION
DIP 1
□■ON
2 seconds delay for the relay. It will be no output for a vehicle with a speed
that is faster than 8 Km/Hr.
DIP 2
□■ON
Increase detector’s sensitivity to avoid the failed detection. Especially in the
case of trailer or trucks.
