The physical crystal and within the module. tuning capacitors may be located external to the shielded radio elements. 2 The modular transmitter must have The modular transmitter has buffered Y buffered modulation/data inputs (if modulation/data inputs to ensure that such inputs are provided) to ensure that the module will comply with part 15 the module will comply with Part 15 requirements under conditions of requirements under conditions of excessive data rates or over- excessive data rates or over- modulation. modulation. 3 The modular transmitter must have its The module contains its own voltage Y own power supply regulation. regulation. 4 The modular transmitter must comply The module is surface mounted to the Y with the antenna and transmission carrier PCB containing etch type system requirements of Sections antennas. Unique RF connectors are 15.203, 15.204(b) and 15.204(c). The populated for host products using flex antenna must either be permanently type antenna. 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 be tested The modular transmitter has been tested Y in a stand-alone configuration, i.e., the in a stand-alone configuration, i.e., the module must not be inside another module was located outside the device during testing for compliance intended host device during testing for with Part 15 requirements. Unless the compliance with part 15 requirements. transmitter module will be battery powered, it must comply with the AC line conducted requirements found in The transmitter module (when powered Section 15.207. AC or DC power lines by a commercially available wall and data input/output lines connected to supply) complies with the AC line the module must not contain ferrites, conducted requirements found in Sec. unless they will be marketed with the 15.207. 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 the case of the module and supporting equipment. Any accessories, peripherals, or support equipment connected to the module during testing shall be unmodified and commercially available (see Section 15.31(i)). 6 The modular transmitter must be The shield of the module is laser etched Y equipped with either a permanently displaying its FCC and Industry Canada affixed label or must be capable of identification numbers. electronically displaying its FCC identification number. The outside of the device into which the (A) If using a permanently affixed label, the module is installed will also display a modular transmitter must be labeled with its label referring to the enclosed module own FCC identification number, and, if the FCC identification number is not visible when with the wording “Contains Transmitter the module is installed inside another device, Module FCC ID: A94424821'' or then the outside of the device into which the similar. 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. (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 comply The outside of the device into which the Y with any specific rules or operating module is installed will also display a requirements that label referring to the enclosed module ordinarily apply to a complete with the wording “Contains Transmitter transmitter and the manufacturer must Module FCC ID: A94424821'' or provide adequate instructions along similar. 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 comply The modular transmitter complies with Y with any applicable RF exposure any applicable RF exposure requirements in its final configuration. requirements in its final configuration A limited 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.
