The range of calibration of the line adjustment is limited. If extreme adjustment is
still unsatisfactory, it will be necessary to adjust the mounting position of the camera
or perform fine adjustments of the lens so as to align it in the rearward direction.
Note:
6. Warning Range Setup:
Click to switch among the four corners of both the left and right square
zones. The corner indicated by the red spot means the zone is currently
adjustable. Click to adjust the warning range. By touching one of the four

appropriate adjustments. Only in this way can the calibration data be saved.
