When the car engine starts, the system automatically activates the monitor and all cameras around the vehicle one by one to check the surrounding view for 10 seconds, then turns off. The system defaults to front view mode. The front view is controlled by an included switch; pressing and holding the control switch for 2 seconds disables the front view video. Press and hold the control switch for 2 seconds to keep the monitor and front camera continuously active when no other trigger is in use, for added convenience. Press the control switch for less than 1 second to switch to side view mode. When the turn signal is activated, the system automatically turns on the monitor and the corresponding side camera based on the left or right turn signal. The monitor and camera will turn off 1.5 seconds after the turn signal is deactivated. Press the control switch for less than 1 second again to return to front view mode.
