To use this switcher, first connect it to a suitable power source (not included). Then, connect your video inputs and outputs according to your setup. When you're done, turn it off properly. Remember, since there's no power supply, you need to get a compatible one. For maintenance, keep it in a clean and dry place. Periodically check the connections to make sure they're secure. If you encounter any issues, consult the official documentation or customer support.
