Appendix A Document Revision Log

1. KDB 996369 D03 statements
2. List of applicable FCC rules:
   The module complies with FCC Part 15.247, FCC Part 15.407.
   FCC ID: 2AD56HLK-RM65 on User manual and on the external of the packaging.
3. Summarize the specific operational use conditions
   When installed in smart terminal products, the host manufacturer must negotiate with the module manufacturer on the final installation method in the system. The host manufacturer installing this module into their product must ensure that the final compost product complies with the FCC requirements by a technical assessment or evaluation to the FCC rules, including the transmitter operation. The host manufacturer has to be aware not to provide information to the end user regarding how to install or remove this RF module in the user’s manual of the end product that integrates this module. The end user manual shall include all required regulatory information warnings as show in this manual.
   The module should be installed and operated with a minimum distance 20cm between the radiator & your body. and if RF exposure statement or module layout is changed, then the host product manufacturer is required to take responsibility of the module through a change in FCC ID or new application. The FCC ID of the module cannot be used on the final product. In these circumstances, the host manufacturer will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization. When the host is a portable device, it is necessary to take a SAR test with your set mounted with this module. Class ll permissive change application is necessary using the SAR report. And an application for a Class ll permissive change from Mobile equipment to Portable equipment is also required.
   Note) Portable equipment: Equipment for which the spaces between the human body and antenna are used within 20cm. Mobile equipment: Equipment used at a position in where the spaces between the human body and the antenna exceeded 20cm.
   1. According to the following requirements of the power supply DCV, power up, about seconds to complete the initial.
   2. iPhone / Android mobile phone WiFi function to open, search to the corresponding Wireless network adapter name (name can be changed according to customer production requirements), click the name of the WiFi and select the connection.
4. open application software (need to install the company’s specific application software development application software interface can be customized according to the customer’s product requirements).
5. Limited module procedures
   The module is not a limited module.
6. Trace antenna designs
   Not applicable
7. RF exposure considerations
   The module complies with FCC radiation exposure limits set forth for an uncontrolled environment. The module should be installed and operated with a minimum distance of 20 cm between the radiator & your body.
8. Antennas
   This module has been approved to operate with the antenna types listed below, with the maximum permissible gain indicated. The module antenna requires professional installation, and the antenna type cannot be changed. The gain cannot exceed 4.69dBi.
9. Label and compliance information
   The host system using this module should have a label in a visible area indicating the following texts: “Contains FCC ID: 2AD56HLK-RM65
10. Information on test modes and additional testing requirements
    When testing host product, the host manufacturer should follow FCC KDB Publication 996369
    D04 Module Integration Guide for testing the host products. The host manufacturer may operate their product during the measurements. In setting up the configurations, if the pairing and call box options for testing does not work, then the host product manufacturer should coordinate with the module manufacturer for access to test mode software.
    The module has been certified for Potable applications. This transmitter must not be colocated or operate in conjunction with any other antenna or transmitter
11. Additional testing, Part 15 Subpart B disclaimer
    The module without unintentional-radiator digital circuity, so the module does not require an evaluation by FCC Part 15 Subpart B. The host should be evaluated by the FCC Subpart B.
12. Note EMI Considerations host manufacturer is recommended to use D04 Module Integration Guide, recommending as “best practice” RF design, engineering testing and evaluation in case non-linear interactions generate additional non-compliant limits due to module placement to host components or properties
13. How to make changes
    This module is a stand-alone module. If the end product involves Multiple simultaneously transmitting condition or different operational conditions for a stand-alone modular transmitter in a host, host manufacturer have to consult with module manufacturer for the installation method in end system. According to the KDB 996369 D02 Q&A Q12, that a host manufacturer only needs to do an evaluation (i.e., no C2PC required when no emission exceeds the limit of any individual device (including unintentional radiators) as a composite. The host manufacturer must fix any failure.

For USA: The frequency stability of all transmission frequencies of U-NII-1, U-NII 2A, U-NII 2C and U-NII-3 meets the requirements of 47 CFR FCC Part 15.407 (g), and the manufacturer declares that their transmission is maintained at Band U-NII-1, U-NII 2A, U-NII 2C and U-NII-3.
