Wipe the LCD panels gently with a soft cloth if they get dirty. Avoid exposing it to extreme temperatures or humidity. If you notice any issues with the function, even though it's a pre - owned unit, check the connections first. And remember, since it may have signs of heavy use, handle it with a bit of extra care during transport and installation.
