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

Trace antenna designs
The module uses the permanent PCB antenna, so this requirement is not applicable to the product.

RF exposure considerations
The host device manufacturer should confirm that a separation distance of 20 cm or more should be maintained between the antenna of this host device and persons during the host device operation.

Antennas
For Bluetooth: PIFA antenna, 0.32dBi
For WiFi 2.4G Band : Ant0: 0.98 dBi, Ant1: 0.98 dBi
For WiFi 5G Band : Ant0: 1.83 dBi, Ant1: 1.53 dBi

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: 2AJVQ-7668AUFT and IC: 22470-7668AUFT”.

Information on test modes and additional testing requirements
The host manufacturer can use the software of Combo Tool to make the Bluetooth transmit continuously, and the software of QA Tool to make the wifi transmit continuously.

Additional testing, Part 15 Subpart B disclaimer
The module only complies with the FCC Part 15.247 and FCC Part 15.407. If the module is installed in the host device, the host manufacturer is responsible for 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.
