FCC regulatory compliance statement
This device complies with Part 15 of the FCC Rules. 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. Warning: changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. This Module complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of 20cm between the radiator and your body. This transmitter must not be co- located or operating in conjunction with any other antenna or transmitter.
Labelling Instruction for Host Product Integrator Please notice that if the FCC identification number is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. This exterior label can use wording such as the following: “Contains FCC ID: 2AOKI- WFM920TUSX1” any similar wording that expresses the same meaning may be used. Installation Notice to Host Product Manufacturer The OEM integrator is responsible for ensuring that the end-user has no manual instruction to remove or install module. The module is limited to installation in mobile application, a separate approval is required for all other operating configurations, including portable configurations with respect to §2.1093 and difference antenna configurations.
Antenna Change Notice to Host manufacturer If you desire to increase antenna gain and either change antenna type or use same antenna type certified, a Class II permissive change application is required to be filed by us, or you (host manufacturer) can take responsibility through the change in FCC ID (new application) procedure followed by a Class II permissive change application.
FCC other Parts, Part 15B Compliance Requirements for Host product manufacturer This modular transmitter is only FCC authorized for the specific rule parts listed on our grant, host product manufacturer is responsible for compliance to any other FCC rules that apply to the host not covered by the modular transmitter grant of certification.

Host manufacturer in any case shall ensure host product which is installed and operating with the module is in compliant with Part 15B requirements.

Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: –Reorient or relocate the receiving antenna. –Increase the separation between the equipment and receiver. –Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
–Consult the dealer or an experienced radio/TV technician for help.

The requirement for KDB 996369 D03:
1.1 List of applicable FCC rules FCC Part 15.247, FCC Part 15.407.

1.2 Summarize the specific operational use conditions EUT use PIFA antenna.

1.3 Limited module procedures The module is a single module, so this requirement is not applicable to the product.

1.4. Trace antenna desig Not support

1.5 RF exposure considerations The host device can be used as mobile device.

1.6 Antennas 2.4G
PIFA antenna :3.66dBi maxExternal type 5G
PIFA antenna :3.55dBi maxExternal type

1.7 Label and compliance information If this certified module is installed inside the host device, then the outside of the host must be labeled with “Contains FCC ID: 2AOKI-WFM920TUSX1

1.8 Information on test modes and additional testing requirements
The host manufacturer can use the software of MT7961 QA to make the WIFI transmit continuously.

1.9. Additional testing, Part 15 Subpart B disclaimer The module only complies with the FCC Part 15.247 and 15.407. If the module is installed in the host device, the host manufacturer is responsible for the compliance to any other FCC rules that apply to the host not covered by the modular transmitter grant of certification. For example, if the host manufacturer markets their product as being Part 15 Subpart B compliant (when it also contains unintentional- radiator digital circuity), then the host manufacturer shall provide a notice stating that the final host product still requires Part 15 Subpart B compliance testing with the modular transmitter installed.
