The radio suppression equipment reduces interference transmitted through the radio speakers by the engine ignition and electrical systems. When installing any radio suppression equipment components, make sure that a good contact is made at all connections. Remove any paint or dirt from between a component and its ground. Tighten all connectors and screws securely according to torque specifications.
