Letter of Agency "I, an officer of Thomas & Darden Inc. do hereby authorize Intertek Testing Services (Mr. Tim Lee / Herbert Wong / Kenneth Wong) to act on our behalf in front of the Federal Communications Commission with respect to all matters relating to certification of equipment under Part 15 and Part 18 of the FCC Rules until further notice." I further certify that no party (as defined in §1.2002(b) of CFR 47, 2004) to this application, including myself, is subject to a denial of federal benefits, that includes FCC benefits, pursuant to Section 5301 of the Anti- Drug Abuse Act of 1988, 21 U.S.C.,862. Dated this 13 day April of 2022 By Signature Nathan D George Printed name CEO Title

Dated this 13 day April of 2022 Attention: Application Examiner Re: Request for Confidentiality. Applicant: Thomas & Darden Inc. FCC ID: 2ANJG-KS400 To whom it may concern , Permanent Confidentiality Request is hereby submitted by Thomas & Darden Inc. to withhold permanently from public review certain portions of the application for equipment certification for the referenced FCC identifiers. This request for confidentiality is made pursuant to 47CFR 0.457(d) and 0.459 of the FCC Rules. In particular, the following sections of the application are to be kept permanently confidential : •Schematics •Detailed Block diagrams •Detailed Operational/Functional Description Short-term Confidentiality Request is hereby submitted by Thomas & Darden Inc. to withhold from public review for a period of 180 days from the date of the Grant of Equipment Authorization and prior to marketing, certain portions of the application for equipment certification for the referenced FCC identifiers. This request for confidentiality is made pursuant to 47 CFR 0.457(d) and 0.459 of the FCC Rules. In particular, the following sections of the application are to be kept confidential for a period of 180 days from the date of Authorization : •Test setup photos •External photos •Internal photos • User manual Rationale for request for confidentiality : Thomas & Darden Inc. has invested considerable time and materials in research and development to produce the referenced product. Disclosure of the permanently confidential portions of this application to competitors would not only give them significant competitive advantages in developing similar products, but would also disclose successful implementation of unpublished, leading edge technology developed by us. Disclosure of the short-term confidential portions of this application during the period of importation and/or distribution would reveal key aspects of proprietary technology to competitors and diminish the value of our investment in research and development. For FCC certification: The fee for confidentiality has been submitted along with the fee for certification. If you have questions or need further information, please contact the undersigned.

INTERTEK TESTING SERVICE FCC ID: 2ANJG-KS400 IC: 23114-KS400 MPE Analysis Report For Maximum Permissible Exposure (MPE) evaluation of the unit, the maximum power density at 20 cm from this transmitter shall be less than the General Population / Uncontrolled MPE limit in OET Bulletin 65 and meet the requirement listed in KDB447498. 1) For the Bluetooth portion of the unit, the measured powers among all the measured channels were within its production tolerance. The maximum source-based time-averaging duty factor is 100%. From these data and its operating configuration, the exposed power density at a distance (R) of 20 cm from the center of radiation of the antenna can be calculated according to OET Bulletin 65 as follow: The EIRP radiated power = 6 dBm + 2.55 dBi = 8.55 dBm (7.2 mW) The radiated (EIRP) source-based time-averaging output power = (7.2 * 1) mW = 7.2 mW The power density at 20 cm = 7.2 / 4πR 2 = 0.00143 mW cm -2 2) For the WiFi portion of the unit, the measured powers among all the measured channels were within its production tolerance. The maximum source-based time-averaging duty factor is 100%. From these data and its operating configuration, the exposed power density at a distance (R) of 20 cm from the center of radiation of the antenna can be calculated according to OET Bulletin 65 as follow: The EIRP radiated power = 18 dBm + 2.82 dBi = 20.82 dBm (120.8 mW) The radiated (EIRP) source-based time-averaging output power = (120.8 * 1) mW = 120.8 mW The power density at 20 cm = 120.8 / 4πR 2 = 0.024 mW cm -2 In the frequency range of 1,500 - 100,000MHz, the MPE limit is 1.0 mWcm-2 for general population and uncontrolled exposure. As the measured power density at 20cm from the transmitter is lower than the MPE limit, the compliance to the MPE limit can be ensured by indicating the minimum 20cm separation between the transmitter's radiating structures and body of the user or nearby persons. The following RF exposure statement is proposed to be included in the user manual: “ FCC RF Radiation Exposure Statement Caution: To maintain compliance with the FCC’s RF exposure guidelines, place the unit at least 20cm from nearby persons.” INTERTEK TESTING SERVICE FCC ID: 2ANJG-KS400 IC: 23114-KS400 In addition, for this product with multiple transmitter and antenna (Bluetooth and WiFi), the requirement of Simultaneous Transmission evaluation has also been considered and has complied with the following conditions of the worse case; MPE1/Limit1 + MPE2/Limit2 ≤ 1 Thus, 0.00143/1 + 0.024/1 = 0.02543 ≤ 1 Bluetooth WiFi It is concluded that no Simultaneous Transmission evaluation is required.
