According to the site of standard reference line, we can put reference objects such
as desks in the back side of the car. Compared with the marked reference objects,
we can adjust the sites and angles of two guide lines are displayed on the monitor.
You will get the accurate and safety guide lines once it coincide with the reference
objects.
Press setting button to enter “guide line adjustment” mode. The system is
defaulted to adjust left guide line firstly. Press the button again to switch to adjust
the right guide line. The up , down left and right buttons are to
adjust the corresponding location of guide lines. The clockwise rotation and
contra rotating buttons are to adjust the angles of guide lines. It is easy to
operate and calibrate. After finishing calibration, switch the reverse gear to save
the information.
Caution: keep the remote control 0.5m-1.0m away from rear view mirror when you use the remote
to adjust the parking lines.
3.3 How to adjust the guide line
Displayonthemonitor
There are three lines---red, yellow, and green, to help drivers estimate the
distance from obstacles. Those three lines are displayed on the monitor when
the car is reversing. The green line is 10 feet away from the back of the car, and
the yellow line is 6.5 feet away. The distant red line is 3.3 feet away from the
back of the car, while the closed red line is 1.3 feet away. Please note that there
is 0.65 feet distance from the car for reference lines shown below.
3.1 About guide line
Regular guide lines are fixed although installation sites of camera and car size are
different. The fixed guide line is not accurate enough for drivers. There is huge
difference between the regular, fixed guide lines, and real guide lines of the car.
It may cause accidents when camera is mounted on the left or right side on the
back side of the car.
