(2) Enter the dash cam homepage and tap the iconto enter settings.

(3) Select ADAS. Follow the onscreen instructions to calibrate the lens then enable this function.

2. What is the ADAS automatic calibration?

When the ADAS function is enabled, each time the dash cam is turned on, if the car speed is greater than 40 km/h, automatic calibration will be stared.

The calibration process may last for 5~8 minutes, during which you should maintain a speed of more than 40 km as much as possible.

3. Why does ADAS calibration fail?

Calibration failures may be out of the following reasons:

• The dash cam’s camera is too far from the car front, i.e. too close to the left and right sides or the upper and lower sides.
• The car speed during most of the calibration process is less than 40 km/h.
• The nighttime light is too dim to accurately identify the lane line.
• The lane line is blurred and unidentifiable.
