CTR line1 controls left video1 and right video1. Whenever line1 connects to
12~24V direct current, then the left screen and right screen of the mirror
would switch to left video1 and right video1 separately. We advise you to
connect CTR1 to reversing line.
CTR line1 controls left video2 and right video2, which is less preferential
than CTR1. That is, when CTR1 and CTR2 connects to battery at the same
time, then only the two videos(left video1 and right video1) from CTR1 can
be displayed on the LCD monitor. When CTR2 connects to current and the
LCD monitor is off, then the monitor keeps be off. However, when the
monitor is on, the left screen and the right screen would switch to left
video2 and right video2 separately.
it's advisable to connect the reversing line
By connecting the green line, the reversing signal is input to the rear view mirror
and reversing video can automatically display on the right side of the screen. (not
connect reversing box)

Generally, to help drivers estimate the distance from obstacles, there are three
lines for reference -red, yellow and green. Those three lines are displayed on the
monitor when car is reversing. The green line is 3m from the back of car and the
yellow line is 2m. The distant red line is 1m from the backside of car while the
closed red line is 0.4m. Both reference lines on the left and right should leave
0.2m space from the car.

3.1 About guide line
Regular guide line is fixed. But installation sites of cameras are different as well
as car size. The fixed guide line is not accurate enough for drivers. There will be a
great difference between regular and fixed guide lines and car's real guide lines,
especially when camera is mounted on the left or right side of car backside. It
may cause accidents.

4.2 Auto dimming how to working
The auto-dimming of our mirror works automatically when you start the engine,
and the indicator will light up. The light sensor in the back of the rear view
mirror will always detect the ambient light. The auto-dimming doesn't work in
the broad day for the adequate daylight. However, when night falls and the
ambient light is weak, the auto-dimming starts to work and automatically dims
to eliminate the glare of rearward-approaching vehicles. Furthermore, the
degree of brightness of the auto-dimming glass depends on the level of the light.
The stronger the light from the back of the car is, the darker the glass is. Hence it
protects drivers from becoming dizzy and avoiding car accident.
Auto-dimming bleaching state

mirror detects the ambient light front light sensor detects the light
from rearward-approaching vehicles.
Auto-dimming working state
4.1 Why need dimming function
● To protect drivers from night glare of headlight.
● It is a function that can improve the car safety level.
● It may cause a series of legal disputes once removed by car dealers or sellers
Chapter Four: Auto Dimming (option)
According to the site of standard reference line, we can put reference objects such
as desks in the back area of car. Compared with the marked reference objects, we
can adjust the sites and angle of two guide lines displayed on the monitor. You will
get the accurate and safety guide lines once they coincide with the reference
objects.
Press setting button is to enter into “guide line adjustment” mode. The system is
defaulted to adjust left guide line firstly. Press the button again will switch to adjust
the right guide line. The up , down left and right buttons are to
adjust the correspondent location of guide lines. The clockwise rotation and
contra rotation buttons are to adjust the angle 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 from rearview mirror when you use the remote to
adjust the parking lines.
