This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.. Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: -- Reorient or relocate the receiving antenna. -- Increase the separation between the equipment and receiver. -- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. -- Consult the dealer or an experienced radio/TV technician for help. To maintain compliance with FCC’s RF Exposure guidelines, This equipment should be installed and operated with minimum distance between 20cm the radiator and your body: Use only the supplied antenna.

Hangzhou Vision Link Intelligence Technology Co., Ltd Federal Communications Commission Equipment Authorization Division 7435 Oakland Mills Road Columbia, MD 21046 USA Date: January 19, 2026 Subject; Modular Transmitter Application Company name: Hangzhou Vision Link Intelligence Technology Co., Ltd FCC ID: 2BS8J-SY155S Dear Sir/Madam, This letter includes the FCC application requirements for Modular Transmitter Approval Request for;- FCC KDB 996369 D01 ‘Module Certification Guide v02; and FCC KDB 996369 D03 OEM Manual v01 In accordance with 47CFR 15.212 Modular Transmitters and KDB 996369 D01 ‘Module Equip Auth Guide v02’. FCC ID： 2BS8J-SY135S has been examined against the following requirements. Requirement per 15.212 and KDB 996369 D01 Explanation from Grantee (do not write yes/no, but explain why product complies/how it is achieved) The radio elements must have the radio frequency circuitry shielded. Physical components and tuning capacitor(s) may be located external to the shield, but must be on the module assembly. The magnetic shielding sheet at the bottom of the coil antenna provides shielding to prevent outward diffusion and interference with other circuits. The module must have buffered modulation/data inputs to ensure that the device will comply with Part 15 requirements with any type of input signal. All modulation and data inputs are buffered by circuitry on the transmitter chip. The module must contain power supply regulation on the module. Power supply regulation is provided by circuitry on the transmitter chip. The module must contain a permanently attached antenna, or contain a unique antenna connector, and be marketed and operated only with specific antenna(s), per §§ 15.203, 15.204(b), 15.204(c), 15.212(a), 2.929(b). The antenna is connected to the module with the means of unique coupling. The module must demonstrate compliance in a stand-alone configuration. This module is powered by 3.3V DC. The module must be labeled with its permanently affixed FCC ID label, or use an electronic display (see KDB Publication 784748). The prototype itself is too small, so the label is shown in the instruction manual. The module must comply with all specific rules applicable to the transmitter, including all the conditions provided in the integration instructions by the grantee. The module complies fully with the operating requirements of Part 15 section C as demonstrated in the test report exhibit. The module must comply with RF exposure requirements Yes, please refer to the MPE report. This module complies with FCC CFR 47 PART 1, 1.1310 RF exposure requirements Integration Instructions for host product manufacturers The following items are submitted in support of application for Modular Transmitter FCC ID as noted above as required by the FCC KDB 996369 D03 OEM Manual v01. These items are provided as integration instructions for host product manufacturers (e.g., OEM instruction manual) to use when integrating a module in a host product. Any requirements that are not applicable to the Module are as indicated below. Summary of requirements and Checklist.
