Using this Sony MVS - 6000 SD video switcher is straightforward. First, connect it to the correct power supply that comes with the package. Make sure all cables are properly plugged in. When operating, keep an eye on the fan hours. If they go over 30,000, you might encounter a system error register issue. For maintenance, clean the switcher regularly to prevent dust build - up which can affect the fan's performance. Also, store it in a dry and cool place when not in use.
