Using this video switcher is easy. First, connect all your input devices to the 18 inputs and your output devices to the 10 outputs. You can use the Carbonite 1M panel to control the switching operations. Since it doesn't come with a power supply, you need to use a suitable external power supply. When using it, keep it in a dry and well - ventilated place to prevent overheating. For maintenance, regularly clean the dust on the surface and inside the switcher. Also, make sure to update the software to SW Ver: 13.0.2.17165 or later to ensure smooth operation.
