Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. 10 / 13 4.9 Information on test modes and additional testing requirements Additional testing requirements should be taking into account for different operating conditions for the transmitter function. If this module is operated as a stand-alone modular in a host: Radiated spurious emission per FCC Part 15.247, 15.249 and RSS247, RSS-210. The host should be operated in all its normal mode with the modular transmitter active. Please follow 4.11 in this document to obtain a best radio engineer design. If this module is operated as multiple simultaneously transmitting modules in a host: Foundation frequency power, Radiated spurious emission per FCC Part 15.249 and RSS-210. Conducted spurious emission and conducted power per FCC part 15.247 and RSS-247. Please contact the modular manufacturer through the contact information shown below 4.12 to get the test software. This module should be operated in transmitter mode with other transmitter for the simultaneous condition. Please follow 4.11 in this document to obtain a best radio engineer design. The procedure rules are provided in 4.3 in this document. As the module manufacturer is still taking responsibility for the compliance of this module, if you have any changes mentioned above, you must advise and get the help from us with the contact information as shown below 4.12. 4.10 Additional testing, Part 15 Subpart B disclaimer Statement: The module complies with and authorized for transmitter rule: FCC Part 15.247, FCC Part 15.249 and Canada RSS-247, RSS-210. However, the host may also contain other unintentional-radiator digital functions / circuits. This digital functions / circuits are required additional FCC / ISED rules: FCC part 15B and relevant ICES standard, which are not covered by the modular certification. The host manufacturer is responsible for compliance to this additional FCC / ISED rules. And the host manufacturer should state the FCC / ISED SDOC compliance information. 4.11 Note EMI Considerations EMI consideration for transmitting simultaneously: This module is stand-alone modular. If the end product has multiple certified modules integrated in a host and transmitting simultaneously: When after radiated emission testing, if there are no additional emissions generated due to simultaneous-transmission operations compared to single transmitter operations testing, it is not necessary to file the additional simultaneous transmission test data. FCC class II permissive changes is no necessary. However, RF exposure for transmitting simultaneously also needed, please refer to 4.6 in this document. To obtain better engineer design while installing this module: It is recommended to place the module as close as possible to the edge of the baseplate. If conditions permit, make the antenna feed point closest to the edge of the baseplate. Please ensure that the module is not covered by any metal shell. Do not lay copper, wire, or place components in the 11 / 13 antenna area of the module PCB. 4.12 How to make changes Only the module grantee is permitted to make permissive changes.
