shield must be soldered to the connectors for the products to function properly. Do not use any jumpers, unshielded wall plates or mid-
span cable connections. These extenders are not compatible with HDBaseT technologies. Prior to signal extension, ensure that the
extension line cable is lying straight and not coiled.
