Applicant/Grantee： H ui Z h ou Gaosh engda Technology Co., LTD FCC ID: 2AC23-W 2N Section 15.212 Modular Transmitters ■ Request for Limited Modular □ Request for Modular Approval Approval Single Modular Approval Requirements Requirements EUT Conditions Comply (Y/N) 1 The radio elements of the The modular have RF own shielding Y modular transmitter must have their own shielding. The physical crystal and tuning capacitors may be located external to the shielded radio elements. 2 The modular have RF own The modular transmitter have Y shielding buffered modulation/data inputs 3 The modular transmitter must The modular transmitter must have Y have its own power supply its own power supply regulation. regulation. 4 The modular transmitter must The modular must to built-in PIFA Y comply with the antenna and Antenna applicant together and transmission system transmission system requirements requirements of of Sections 15.203, 15.204(b) Sections15.203, 15.204(b) and and 15.204(c). 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 Section 15.203 is not applicable to modules but can apply to limited modular approvals under paragraph (b) of this section. 5 The modular transmitter must The EUT module can’t be operated Y be tested in a stand-alone by its own due to its power-less configuration, i.e., the module characteristic and hence needs must not be inside another external power supply to make it device during testing for function. Under testing condition, no compliance with Part 15 matter in pure verification or requirements. Unless the manufacturing stage, the specified

transmitter module will be test fixture must be provided to help battery powered, it must testing the function and performance comply with the AC line of the EUT sample. 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 the length typical of actual use or, if that length is unknown, at least 10 centimeters to insure that there is no coupling between 6 The modular transmitter must The FCC identification number can Y be equipped with either a put on the modular with either a permanently affixed label or permanently affixed label must be capable of electronically displaying its FCC identification number. (A) If using a permanently affixed label, the modular transmitter must be labeled with its own FCC identification number, and, if the FCC identification number 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: 2AC23-W 2N ” or “Contains FCC ID: 2AC23-W 2N .” 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. (B) 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. 7 The modular transmitter must The instructions will be provided Y comply with any specific rules and apply to a complete transmitter or operating requirements that and comply with specific rule. 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. 8 The modular transmitter must The total power density of modular Y comply with any applicable RF transmitter final configuration exposure requirements in its comply with FCC RF Exposure

final configuration. requirment A modular approval may be granted for single or split modular transmitters that do not comply with all of the above requirements, e.g., shielding, minimum signaling amplitude, buffered modulation/data inputs, or power supply regulation, if the manufacturer can demonstrate by alternative means in the application for equipment authorization that the modular transmitter meets all the applicable Part 15 requirements under the operating conditions in which the transmitter will be used. Limited modular approval also may be granted in those instances where compliance with RF exposure rules is demonstrated only for particular product configurations. The applicant for certification must state how control of the end product into which the module will be installed will be maintained such that full compliance of the end product is always ensured.
