the power cable
Figure 14 shows the power line, with a variety of color plugs on one end, and then the 3PIN connector on the rear
panel of the device. Red lines and black lines are directly received from the car's battery. The red line is connected
to the positive pole and the black line is negative. The yellow line contacts the fire line, the host equipment
automatically opens after the car turns the key, and shuts off after turning off the car key. The yellow line picks up
the gear when the car keys turn on all the dashboard lights (that's the stall before the car starts the motor).
Note:
1) Make sure the voltage of the battery is between 6V - 36V before connecting, otherwise it will burn the equipment.
2) After connecting the line, pay attention to the insulation between the power cord and prevent the power line from
short-circuiting the battery.
3) The yellow line must be connected to the ignition line, otherwise the device will not support the delayed shutdown,
and the final video, video, will be lost.
