Plug the plug into the cigarette lighter first, and the machine will start automatically (some need to press the power button for a long time to start). Insert the purchased memory card. Let me explain here that you don't need to buy too big a memory card, because now the driving recorders are automatically cycled, that is to say, when the memory is full, the previous video will be automatically deleted and cycled indefinitely. Then set up the driving recorder. There are several points: time, clarity, night vision effect, recording function, emergency video recording and so on. The driving recorder will have a setting (menu) button with a digital description on it. If you find the menu button, there will be a time option. Click enter to set the time to Beijing time.
