The line-tracking sensor has been calibrated before leaving the factory, and you do not need to

calibrate it again. Just like the reset button of digital products, you don't need to use it in most

cases. Incorrect calibration methods can also cause the line-tracking sensor to fail.

If you find that the line-tracking sensor does not recognize the black lines that can be recognized

normally, then you can try to calibrate it. Methods as below:

1. Place the car on the black block of the map which delivered with the product, and make sure

that the 5 sensors are in the black area. as the picture shows:

2. Long press the calibration button for about 1 second. At this time, the car lights flash and the

calibration is completed.

3. Check the calibration result: when the calibration done, place the line-tracking sensor in the

black area, the line-tracking indicator is on, and the indicator is off in the white area, indicating

that the calibration is correct.
