(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.

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.
