Using this AJA Ki Pro Rack 1RU video recorder and player is easy. First, connect it to a power source using the included power supply. When recording or playing videos, keep in mind that some pixels on the screen are dimmer than others, but this won't affect the overall performance too much. For maintenance, make sure to keep it in a clean and dry place. Don't expose it to extreme temperatures or humidity. And always handle it gently to avoid any damage.
