There will be a color square in the middle of the screen, the square is with three color modes:
a) Green, it means the relative angle and distance between the driver and driver fatigue
monitoring system is appropriate.
b) Red, it means the device is too closer to the driver or the angle of the device is not suitable.
The assistant should try to adjust the relative distance or angle of device, make sure that the
driver’s face is fully presented in the middle of the screen, being inside the color square. After
finishing above steps, the color of the square may turn green.
By the way, the assistant can adjust the pitch angle when the fixing hex nut is loose, as the
below figure. After adjusting to appropriate angle of the device, tighten the fixing hex nut.

c) Yellow, it means the relative distance and the pitch angle of the device is appropriate, but the
included angle between the device and the front view of the driver is greater than +/- 10 degrees,
the assistant should rotate the device on the dashboard slightly until the square turn and stay
green.
2) After making sure the color square stay green, the assistant should press the "start" button and
follow the voice to guide to begin calibrating, the driver must keep the view straight as in normal
driving during the calibrating process which lasts about 10S. After calibrating, the device will
feedback by voice:
a)"Calibration is successful" indicates a successful calibrating. Then the APP will exit the
real-time mode automatically.
b)"To left" or "To right" indicates calibration is unsuccessful because the driver’s head is inclined
left or right. Slightly adjust the device angle again, and then repeat the calibrating process.
By touching the "cancel" button, you can exit the calibrating process at any time.
3) After finishing calibrating, the assistant should mark the current device position on the dashboard
by pencil carefully, then fixing the device on the marking position by 3M glue. According to above
steps, the calibration and installation is done.
