FormattingSteps:After installing the memory card, please enter the DVR menu, find the format option, and click to format the memory card. (Important: Formatting the memory card on the computer is an incorrect operation. Please format the memory card on the DVR's menu option.) AboutTheReversingAssistFunction: Suppose the kit you ordered includes a rearview camera and you need to implement the reversing assist function. In that case, you need to connect the red signal wire of the rearview camera to the car's reversing light (the light will come on when reversing). If you don't need the reverse assist function, disconnect the red signal wire and leave it unconnected. About 24-Hour Parking Monitoring:If you need the 24-hour parking monitoring function, you can order the corresponding Buck Line accessories to replace the car charger. Through Buck Line, the DVR power can be obtained directly from the car battery or car ACC, so that the DVR can maintain normal recording work even when the car is turned off. (Since different car models have different battery interfaces or ACC interfaces, it is not recommended to install it by yourself. It is recommended to find a professional to install the Buck Line.)
