Using this QSC Q - SYS tabletop touch screen controller is easy. Just connect it to a compatible power source (since it doesn't have a power supply included). When using, keep it on a flat and stable surface to avoid accidental knocks. For maintenance, use a soft, dry cloth to clean the screen regularly. Don't use harsh chemicals or abrasive materials as they can damage the screen. If you have any issues, refer to the QSC official website for support. Also, make sure the environment where you place it is not too humid or dusty to ensure its long - term performance.
