Monolith Electric (Changzhou) Co., Ltd. 2020/1/14 To: SGS North America Inc. 620 Old Peachtree Road SUITE 100 Suwanee, Georgia United States Dear Sir/Madam, Re: Request for FCC module certification FCC ID: 2AVLFBT645 We hereby request a Modular certification for the FCC ID referenced above. The device meets the requirements below. • The module has metal case covering top and sides as its own RF shielding. The shielding at bottom is implemented by the GND copper plane in PCB substrate. Please see External Photo.pdf • The module has buffered modulation/data inputs to ensure that the device will comply with Part 15 requirements with any type of input signal; 32-bits microcontroller with 256kB flash memory and 16kB RAM as an embedded processor to buffer the data, it's controlled by the chip CP005-QFN32. • The module has power supply regulation on the module; The power supply of blue tooth module can be in the range 2.2V to 3.6V, it's controlled by the chip CP005-QFN32 • The module has demonstrated compliance in a stand-alone configuration; • The module has a permanently attached antenna, or contain a unique antenna connector, and be marketed and operated only with specific antenna(s), per Sections 15.203, 15.204(b), 15.204(c), 15.212(a), 2.929(b); • The module will be labeled with its permanently affixed FCC ID label. The label position of module is clearly indicated. Please see the Label & Location.pdf • The module does comply with all specific rules applicable to the transmitter including all the conditions provided in the integration instructions by the grantee; The module is compliant with all applicable FCC rules. Detail instructions are given in the User Manual • The module does comply with RF exposure requirements. The modular comply with applicable RF exposure requirements. Please see MPE Report. pdf Sincerely, Name: Xia Qing Title: Quality Engineer Company: Monolith Electric (Changzhou) Co., Ltd. Telephone: 0519 83189730 Monolith Electric (Changzhou) Co., Ltd. FCC Modular definitions, From FCC KDB 996369 D01 Module Equip Auth Guide v02 A. Single-modular transmitter is a self-contained, physically delineated, component for which compliance can be demonstrated independent of the host operating conditions, and which complies with all eight requirements of Section 15.212(a)(1) as summarized below. See Section 15.212 for more detailed information, and Section 2.901 (and sub- sections that follow) for general certification requirements. B. Limited single-modular transmitter is a transmitter that does not meet all eight requirements listed in Section 15.212(a) (1), and compliance can be demonstrated only for specific host and applicable operating conditions in which the transmitter will be used. For example, manufacturers have flexibility with respect to requirements such as module shielding, buffered modulation/data inputs and power supply regulation. If one or more of these functions (shielding, buffered modulation/data inputs and power supply regulation) are provided by a specific host or hosts, then the module can be granted as a limited module that is limited to that specific host or hosts. The responsible party must demonstrate how it will retain control over the final installation of the device, such that compliance of the product is ensured by limiting the installation to a specific host or hosts, for example.
