Applicant/Grantee Wahoo Fitness LLC FCC ID: PADWF125 Modular Transmitters Request for Modular Approval Request for Limited Modular Approval Requirements EUT Conditions Comply（Y/N） Single Modular Approval Requirements 1 The radio elements of the modular Refer to the external photo N transmitter must have their own shielding. The physical crystal and tuning capacitors may be located external to the shielded radio elements. 2 The modular transmitter must have buffered All input to the modules are Y modulation/data inputs (if such inputs are buffered through provided) to ensure that the module will microprocessor inputs. comply with modular approval requirements under conditions of excessive data rates or over- modulation. 3 The modular transmitter must have its own Internal power regulators Y power supply regulation. Refer to the Block-diagram 4 The modular transmitter must comply with Refer to the internal photo Y the antenna and transmission system requirements. 5 The modular transmitter must be tested in a The EUT was tested in a Y stand- alone configuration, i.e., the module standalone configuration via a must not be inside another device during SD extension cable testing. Unless the transmitter module will be Refer to the test setup photo battery powered, it must comply with the AC line 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 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 equipped Refer to the external photo Y with either a permanently affixed label or and the user manual must be capable of electronically displaying its FCC identification number. 7 The modular transmitter must comply with Refer to the user manual Y any specific rules or operating requirements that 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 comply with Refer to the RF exposure Y any applicable RF exposure requirements in statement for more details. 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 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.
