Conductive chassis rails connected to earth ground. This provides the path for connecting shields to earth ground. 4. Front panel screws properly tightened. For minimum RF emissions, it is essential that the conditions above be implemented; failure to do so could compromise the FCC compliance of the equipment containing the modules. Table 1-3.
