OEM Integrators Installation Manual 2.1 Important Notice to OEM integrators ⚫ This module is limited to OEM installation ONLY. ⚫ This module is limited to installation in mobile or fixed applications, according to Part 2.1091(b). ⚫ The separate approval is required for all other operating configurations, including portable configurations with respect to Part 2.1093 and different antenna configurations ⚫ For FCC Part 15.31 (h) and (k): The host manufacturer is responsible for additional testing to verify compliance as a composite system. When testing the host device for compliance with Part 15 Subpart B, the host manufacturer is required to show compliance with Part 15 Subpart B while the transmitter module(s) are installed and operating. The modules should be transmitting and the evaluation should confirm that the module's intentional emissions are compliant (i.e. fundamental and out of band emissions). The host manufacturer must verify that there are no additional unintentional emissions other than what is permitted in Part 15 Subpart B or emissions are complaint with the transmitter(s) rule(s). Antenna Installation 1) The antenna must be installed such that 20 cm is maintained between the antenna and users. 2) The transmitter module may not be co-located with any other transmitter or antenna. 3) To comply with FCC/IC regulations limiting both maximum RF output power and human exposure to RF radiation, the maximum antenna gain including cable loss in a mobile exposure condition must not exceed the values in section 2.2. In the event that these conditions cannot be met (for example certain laptop configurations or co- location with another transmitter), then the FCC/IC authorization is no longer considered valid and the FCC ID/IC ID cannot be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC/IC authorization.

RF_734_05 FCC Modular Approval Request Page 1 of 2 28-12-2022 Modular Approval Request FCC (KDB 996369 D01 & Part 15.212) FCC ID: COF-BM25-EXT Items to be covered by Single modular transmitters. Answer from applicant 1. 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. Y The EUT provides the RF shielding. See EUT photo. 2. 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. Y The EUT has its buffered modulation. Main chip, CYW43455, the WLAN host interface supports SDIO v3.0 modes, providing a raw data transfer rate up to 300 Mbps when operating in 4-bit mode. An independent, high-speed UART is provided for the Bluetooth host interface. 3. The module must contain power supply regulation on the module Y The EUT has its own power supply regulation. One Buck regulator, multiple LDO regulators, and a power management unit (PMU) are integrated into the main chip CYW43455. All regulators are programmable via the PMU. These blocks simplify power supply design for Bluetooth and WLAN functions in embedded designs. 4. 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). Y The EUT meets the FCC antenna requirements; unique antenna connector and photo of antenna are shown in the test report. 5. The module must demonstrate compliance in a stand-alone configuration. Y The EUT was tested with a test board, please see test report and setup photo. 6. The module must be labeled with its permanently affixed FCC ID label, or use an electronic display (see KDB Publication 784748). Y Please see the exhibition of label file for the FCC ID of this module. And also in the exhibition of user manual, there are instructions given to the OEM on how to label the end product. 7. The module must comply with all specific rules applicable to the transmitter, including all the conditions provided in the integration instructions by the grantee. Y The EUT is compliant with all applicable FCC rules. Details instructions for maintaining compliance are RF_734_05 FCC Modular Approval Request Page 2 of 2 28-12-2022 given in the user manual. 8. The module must comply with RF exposure requirements. Y The EUT complies with Rf exposure requirement. Items to be covered by Split modular transmitters. Answer from applicant 1. The modular transmitter must comply with all requirements of a single modular transmitter except for items (1) & (5) of the above single modular approval requirements. 2. Only the radio front end must be shielded. The physical crystal and tuning capacitors may be located external to the shielded radio elements. The interface between the split sections of the modular system must be digital with a minimum signalling amplitude of 150 mV peak-to-peak. 3. Control information and other data may be exchanged between the transmitter control elements and radio front end. 4. The sections of a split modular transmitter must be tested installed in a host device(s) similar to that which is representative of the platform(s) intended for use. 5. Manufacturers must ensure that only transmitter control elements and radio front end components that have been approved together are capable of operating together. The transmitter module must not operate unless it has verified that the installed transmitter control elements and radio front end have been authorized together. Manufacturers may use means including, but not limited to, coding in hardware and electronic signatures in software to meet these requirements, and must describe the methods in their application for equipment authorization. Note: A limited modular approval (LMA) may be granted for single or split modular transmitters that comply partially with the requirements above.
