Using this Ross Vision QMD 1 M/E Video Switcher is easy. First, connect it to the correct power supply that comes with it. Then, if you have a screen rack mount, install the screen. Remember, you'll need to provide your own DVI and USB cables. When operating, keep in mind that the screen is missing the 'Next' key cap, so you might need to find an alternative way to perform that function. As for the power supply, since it's a third - party one without a locking sleeve, make sure it's securely plugged in to avoid any power disruptions. For maintenance, keep the switcher in a clean and dry place. Regularly check the connections to ensure they're tight. If you notice any issues, don't hesitate to seek professional help.
