Tips:
BAT yellow wire and ACC red wire cannot be screwed together to connect
to the ACC line to take power. After power off and power on again, the recording
time will not be saved. Other functions are normal. Please take power according
to the usage requirements!
The power cord is recommended to be connected directly to the positive and
negative terminals of the vehicle battery, or after the battery is connected to
the fuse box, connect the positive and negative poles of the power supply. It is
not recommended to connect to the metal conductor in the car as the ground
wire, otherwise, a negative pulse will be generated to interfere with the normal
operation of the monitor.
