8. The requirement for KDB 996369 D03:

8.1 List of applicable FCC rules

FCC Part 15. 247 and FCC Part 15.407.

8.2 Summarize the specific operational use conditions
None

8.3 Limited module procedures

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

8.4 Trace antenna designs

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

8.5 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.

8.6 Antennas

For Bluetooth: PIFA antenna, 0.13dBi
For 2.4G wifi: Ant0: 1.91dBi, Ant1: 1.31dBi
5G wifi: Ant0: 3.52dBi, Ant1:3.44dBi

8.7 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: 2AJVQ-7668AUC and IC: 22470- 7668AUC”.

8.8 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.

8.9 Additional testing, Part 15 Subpart B disclaimer

The module only complies with the FCC Part 15.247 and FCC 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.
