Ultrasonic detector working status and indicator light status
A. After powering, the power indicator (Power/Red) is on,
1. When the ultrasonic sending or receiving of the detector is not normal, the status light
(State/green) Flash 15 times a second,
2. When the ultrasonic sending and receiving of the detector are normal, but there is no car, pass
Normally, the status light (State/green) flashes 3 times a second,
3. When the ultrasonic sending and receiving of the detector are normal, but there is no car, no
During the communication, the status light (State/green) flashes once in one second,
4. When the ultrasonic sending and receiving of the detector are normal, and there are cars,
Status light (state/green) has been on,
B. Flexible setting alarm distance (measured 0.3- -4.00 meters) see the jump line setting table. 

When the vehicle is in place and the determination distance is less than the preset distance, 

the red LED light is on outside, otherwise the green LED light is turned on.
