Using the Datavideo SE - 800 digital video mixer is easy. First, connect your DV devices to the four inputs. Since it doesn't come with a power supply, you'll need to use your own suitable power adapter. When using it, make sure the power source is stable to avoid any video glitches. As for maintenance, keep it in a dry and clean place. Wipe it with a soft cloth regularly to remove dust. If you encounter any problems, check the connections first before seeking further technical support.
