1. How to enable ADAS function?

• Press function button on the dash cam, select ADAS and press the power button once to turn on ADAS.
• Tap Settings on the device homepage in 70mai app, tap ADAS to enter the ADAS setting page, you can enble the ADAS function and follow the onscreen instructions to finish the lens calibration. Note that you need maintain a driving speed above 40 km/h and drive on clearly marked road during calibration.
• Select the ADAS warning or prompts you would like to receive in 70mai app. If the speaker volume is turned off, you will not receive ADAS broadcast.

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 exceeds 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.
