| Limited Single Modular Approval. The antennas used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter except in accordance with FCC multi-transmitter product procedures. This module does not contain a shield and therefore is limited. The module is only designed to be implemented in Grantee's host devices. The module is limited, requiring the host integrator to file a Class II permissive change for each specific host per the test plan defined in the module integration instructions because it has no RF shielding. Even though the grantee is the host integrator, only the grantee can file C2PC. |
