To use the 360 Systems MAXX-1200HD High-Definition Broadcast Server, first, make sure it's connected to the correct power supply. Connect your input device to the SDI input and your output devices to the SDI outputs. You're then ready to start broadcasting high-definition content. When handling the server, avoid dropping or shaking it as it may damage the internal components. Keep it in a cool, dry place to prevent overheating. Regularly check the power supply for any signs of wear or damage. If you notice any issues with the server's performance, contact the manufacturer's support team.
