Taisync Ltd. 070920-02b Request for Modular/Limited Modular Approval Date: December 15, 2025 Subject: Manufacturer’s Declaration for ☒ - Modular Approval ☐ - Split Modular Approval ☐ - Limited Modular Approval ☐ - Limited Split Modular Approval Confidentiality Request for: ______2AQVB-DN2458G______ 8 Basic Requirements – FCC Part 15.212(a)(1) For Items Marked “NO(*)”, the Limited Module Description Must be Filled Out on the Following Pages Modular Approval Requirement Requirement Met 1. The modular transmitter must have its own RF shielding. This is intended to ensure that the module does not have to rely upon the shielding provided by the device into which it is installed in order for all modular transmitter emissions to comply with FCC limits. It is also intended to prevent coupling between the RF circuitry of the module and any wires or circuits in the device into which the module is installed. Such coupling may result in non-compliant operation. The physical crystal and tuning capacitors may be located external to the shielded radio elements. 15.212(a)(1)(i) ☒ - YES ☐ - NO(*) Details: <The radio elements of the modular transmitter have their own shielding.> 2. The modular transmitter must have buffered modulation/data inputs (if such inputs are provided) to ensure that the module will comply with FCC requirements under conditions of excessive data rates or over-modulation. 15.212(a)(1)(ii) ☒ - YES ☐ - NO(*) Details: <The modular has buffered data inputs, it is integrated in chip. Please refer to schematics.> 3. The modular transmitter must have its own power supply regulation on the module. This is intended to ensure that the module will comply with FCC requirements regardless of the design of the power supplying circuitry in the device into which the module is installed. 15.212(a)(1)(iii) ☒ - YES ☐ - NO(*) Details: <The RF module has its own independent power supply, you can refer to the module schematic.> 4. The modular transmitter must comply with the antenna and transmission system requirements of §§ 15.203, 15.204(b), 15.204(c), 15.212(a), and 2.929(b). 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 15.212(b). 15.212(a)(1)(iv) ☒ - YES ☐ - NO(*) Details: <Can refer the internal photo.> 5. The modular transmitter must be tested in a stand-alone configuration, i.e., the module must not be inside another device during testing. This is intended to demonstrate that the module is capable of complying with Part 15 emission limits regardless of the device into which it is eventually installed. Unless the transmitter module will be battery powered, it must comply with the AC line conducted requirements found in Section 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 Section 15.27(a)). The length of these lines shall be 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 or commercially available (see Section 15.31(i)). 15.212(a)(1)(v) ☒ - YES ☐ - NO(*) Details: <Modules can be independently configured and tested via the TTL interface. You can refer to the test setup photos.> Taisync Ltd. 070920-02b Modular Approval Requirement Requirement Met 6. The modular transmitter must be labeled with its own FCC ID number, or use an electron display (see KDB Publication 784748). If using a permanently affixed label with its own FCC ID number, if the FCC ID is 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. This exterior label can use wording such as the following: “Contains Transmitter Module FCC ID: XYZMODEL1” or “Contains FCC ID: XYZMODEL1.” Any similar wording that expresses the same meaning may be used. The Grantee may either provide such a label, an example of which must be included in the application for equipment authorization, or, must provide adequate instructions along with the module which explain this requirement. In the latter case, a copy of these instructions must be included in the application for equipment authorization. If the modular transmitter uses an electronic display of the FCC identification number, the information must be readily accessible and visible on the modular transmitter or on the device in which it is installed. If the module is installed inside another device, then the outside of the device into which the module is installed must display a label referring to the enclosed module. This exterior label can use wording such as the following: “Contains FCC certified transmitter module(s).” Any similar wording that expresses the same meaning may be used. The user manual must include instructions on how to access the electronic display. A copy of these instructions must be included in the application for equipment authorization. 15.212(a)(1)(vi) ☒ - YES ☐ - NO(*) Details: <Can refer the label.> 7. The modular transmitter must comply with all specific rule or operating requirements applicable to the transmitter, including all the conditions provided in the integration instructions by the grantee. A copy of these instructions must be included in the application for equipment authorization. For example, there are very strict operational and timing requirements that must be met before a transmitter is authorized for operation under Section 15.231. For instance, data transmission is prohibited, except for operation under Section 15.231(e), in…

Non-SDR (Software Defined Radio) Cover Letter Refer to KDB 442812 D01 SDR apps Guide v02r03. The following six questions can be used for determining if a radio can elect to be, or must be an SDR. 1. Can the RF parameters of the device be altered through software? Yes - go to 2. No, not an SDR No 2. Can third parties not permitted by the Commission through specific filings modify, configure, or load different software, or make configuration settings to operate the device or host hardware radio frequency parameters (frequency range, modulation type, maximum output power or other radio parameters) in any other way than granted (or expected to be granted)? Yes, must be an SDR. No - go to 3. No 3. Is the device capable of operating in any other in any other way than granted, or will be, granted? Yes, - go to 4. No - go to 5. No 4. Is this a Part 15 client Device as defined in Section 15.202 (as opposed to a master device)? Yes, qualifies as a part 15 client devices - go to 5. No, must be an SDR. 5. Does the manufacturer elect SDR? Yes, elects to be an SDR. No, Not an SDR No Conclusion: According to the above questions reply, we can confirm this device (FCC ID: 2AQVB- DN2458G) must be a Non-SDR device. __________________ Name: Yan Li Title: CEO Date: November 4, 2025
