1. How to enable ADAS function?

1. Open the 70mai app, tap the icon  and tap Dash cam settings.
2. Connect dash cam Wi-Fi and then select ADAS. 
3. Follow the onscreen instructions to calibrate the lens then enable this function.
4. Select the ADAS warning or prompts you would like to receive.

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 started.

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:

• Make sure the lens has been calibrated following the onscreen calibration instructions. Or you can disable and then enable ADAS again to enter the lens calibration process.
• 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.

4. Tripod head position and ADAS lens calibration

• The default position of the tripod head is exactly the lens position in the ADAS lens calibration. Thus if you adjust the tripod head position in dash cam settings, please re-calibrate lens in ADAS.
• When ADAS is enabled, any adjustment of tripod head position in the dash cam homepage will stop ADAS broadcast. In this case, calibrate the tripod head in the dash cam homepage or restart the dash cam, and then ADAS broadcast will recover.
