Certification designating a U.S. Agent for service of process: As required by section 2.911(d)(7), the applicant must designate a contact located in the United States for purposes of acting as the applicant’s agent for service of process, regardless of whether the applicant is a domestic or foreign entity. An applicant located in the United States may designate itself as the agent for service of process. In either scenario, the designation of the U.S. agent for service of process should be provided as an attachment to the equipment authorization application. The applicant must provide a written certification, which must: i. Be signed by both the applicant and designated agent for service of process, if the agent is different from the applicant. ii. Acknowledge the applicant’s consent and the designated agent’s obligation to accept service of process. iii. Provide a physical U.S. address and email for the designated agent. iv. Acknowledge the applicant’s acceptance to maintain an agent for no less than one year after the grantee has terminated all marketing and importation or the conclusion of any Commission-related proceeding involving the equipment. Unofficial information provided by FCC personnel on February 14, 2023, via the monthly call with the TCB Council: The Agent for Process of Service:  cannot be a TCB or affiliated with a TCB (e.g. could not be a person who works for a TCB or a company that owns or is owned by the TCB)  cannot be a [FCC recognised] Lab or affiliated with a test lab (e.g. could not be a person who works for a Lab or a company that owns or is owned by the Lab)  Agent can be Individual Entity or a Company Entity  Agent Entity must be located in US, US address/phone  Entity acting as Agent must have FRN (best practice, put FRN on Agent Letter)  Agent letter does not have to be FCC ID specific, can be general Agent for Grantee For devices being marketed or for which marketing has ceased for less than 1 year, if the Agent for Process of Service changes, then for every TC Number the TCB must request the FCC to put application into Audit Mode and Agent Letter needs to be updated (superseded). NOTE: The U.S. Agent for Service of Process should not be confused with the authorized agent used for signing the 731 form, other cover letters within the application, and/or the agent who may interface with the TCB.

GREEN SIDE / BAT 7 / 400, AV. ROUMANILLE / BP 309 / 06906 SOPHIA-ANTIPOLIS / FRANCE MODULAR APPROVAL LETTER Date: 07/30/2025 FCC ID: 2AAQS-ISP2454 Modular Approval Requirement Answers (i) The radio elements of the modular transmitter must have their own shielding. The physical crystal and tuning capacitors may be located external to the shielded radio elements. The module has a metal shield over the radio elements (ii) The modular transmitter must have buffered modulation/data inputs (if such inputs are provided) to ensure that the module will comply with part 15 requirements under conditions of excessive data rates or over-modulation. All data is buffered (iii) The modular transmitter must have its own power supply regulation. The module includes its own LDOs and regulators (iv) The modular transmitter must comply with the antenna and transmission system requirements of §§ 15.203, 15.204(b) and 15.204(c). The antenna must either be permanently attached or employ a “unique” antenna coupler (at all connections between the module and the antenna, including the cable). The “professional installation” provision of § 15.203 is not applicable to modules but can apply to limited modular approvals under paragraph (b) of this section. The antenna is permanently attached to the module inside the substrate (v) The modular transmitter must be tested in a stand-alone configuration, i.e., the module must not be inside another device during testing for compliance with part 15 requirements. Unless the transmitter module will be battery powered, it must comply with the AC line conducted requirements found in § 15.207. AC or DC power lines and data input/output lines connected to the module must not contain ferrites, unless they will be marketed with the module (see § 15.27(a)). The length of these lines shall be the length typical of actual use or, if that length is unknown, at least 10 centimeters to insure that there is no coupling between the case of the module and supporting equipment. Any accessories, peripherals, or support equipment connected to the module during testing shall be unmodified and commercially available (see § 15.31(i)). This is the case (vi) The modular transmitter must be equipped with either a permanently affixed label or must be capable of electronically displaying its FCC identification number. The module has the FCC identification number marked on the product (vii) The modular transmitter must comply with any specific rules or operating requirements that ordinarily apply to a complete transmitter and the manufacturer must provide adequate instructions along with the module to explain any such requirements. A copy of these instructions must be included in the application for equipment authorization. The user manual contains such explanations (viii) Radio frequency devices operating under the provisions of this part are subject to the radio frequency radiation exposure requirements specified in §§ 1.1307(b), 1.1310, 2.1091, and 2.1093 of this chapter, as appropriate. Applications for equipment authorization of modular transmitters under this section must contain a statement confirming compliance with these requirements. The modular transmitter must comply with any applicable RF exposure requirements in its final configuration. Technical information showing the basis for this statement must be submitted to the Commission upon request. The module complies with the RF exposure requirements Sincerely, Contact Name: Christopher Barratt Title: President Insight SIP

The materials contain trade secrets and proprietary information not customarily released to the public. The public disclosure of these matters might be harmful to the Applicant and provide unjustified benefits to its competitors. We are also hereby request Short-Term Confidentiality for 180 days after the grant as outlined in Public Notice DA 04-1705. This provision will give Insight SiP temporary confidentiality of commercially sensitive information prior to product release. The requested permanent and Short-Term Confidential exhibits are listed as follows: PERMANENT & SHORT-TERM CONFIDENTIAL LIST Exhibit Description PERMANENT 1 Block Diagram 2 Schematics 3 Part Lists 4 Operation Description 5 Internal Photos SHORT-TERM 6 External Photos 7 Test-Setup Photos 8 User Manual 9 - The Applicant understands that pursuant to Rule 0.457, disclosure of this application and all accompanying documentations, where applicable, will not be public before the date of the Grant for this application. Please note that we request that the internal photo are kept confidential permanently since the component placement is a trade secret that is owned by Insight Sip. This information is not available to the public since the module is over-molded with an epoxy mold compound that is difficult to remove. The components are not sold under NDA as this is not necessary to achieve the level of protection that we consider necessary.
