Important: To reduce the risk of voiding FCC and CE compliance and reducing the performance of the ET 350 monitor, when making your own cable, reduce the sensitivity of the ET 350 monitor to electrical and radio frequency noise by connecting the cable shield to the connector shield (360 degree shield) on both ends of the cable.
*N.C. = No Connection
