Regulation Notice

Regulatory notice to host manufacturer see KDB Publication 996369 D04

for guidance.

This module has been granted modular approval as below listed FCC rule parts.

FCC Rule parts 15C(15.247 / 15.407)

RF exposure considerations
The end manual should include regulatory information/warnings about:

The module must be installed and operated with a minimum distance of 20 cm between the antenna radiating structures and nearby persons.
The module is classified as a mobile device for RF exposure purposes.
The antenna(s) used for this module must not be simultaneous with any other antenna or transmitter, except in accordance with FCC multiple transmitter product procedures.
As long as the three conditions above are followed, further FCC equipment authorizations may not be required. Refer to FCC publication 996369 D04 for guidance.

Operational restriction according to KDB 987594 D01

The device cannot provide a direct connection to source the internet from a wired or direct connection to other devices over a 6 GHz air interface.
The device is prohibited for control of or communications with unmanned aircraft systems, including drones.
The device shall never operate above the maximum output power allowed by the rule: 24 dBm & -1dBm/MHz when under the control of a low-power indoor AP or subordinate and shall be lower or equal to the power advertised by the indoor low-power AP or subordinate.
The device shall always initiate transmission under the control of a low-power indoor AP or subordinate except for brief transmissions before joining a network.
These short messages will only occur if the client has detected an indoor AP or subordinate operating on a channel. These brief messages will have a time- out mechanism such that if it does not receive a response from an AP it will not continually repeat the request.

Any new antenna type, higher gain than the listed antenna should be met the requirements of FCC rules 15.203 and 2.1043 as permissive change procedure.

Label and compliance information

End Product Labeling
The module is labeled with its own FCC ID and IC Certification Number. If the FCC ID and IC Certification Number are 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. In that case, the final end product must be labeled in a visible area with the following:

Contains FCC ID: BEJLGSBWAX12
Contains IC: 2703H-LGSBWAX12

Information on test modes and additional testing requirements
OEM integrator is still responsible for testing their end-product for any additional compliance requirements required with this module installed (for example, digital device emissions, PC peripheral requirements, the additional transmitter in the host, etc.).

Additional testing, Part 15 Subpart B disclaimer
The final host product also requires Part 15 subpart B compliance testing with the modular transmitter installed to be properly authorized for operation as a Part 15 digital device.
