FCC ID: 2ACSVHF-LPD100 Section 15.212 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 transmitter must have their own shielding. The physical crystal and tuning capacitors may be located external to the shielded radio elements. Refer to external photos. This module does have shield cover. Y 2 The modular transmitter must have buffered modulation/data inputs (if such inputs are provided) to ensure that the module will comply with part 15 requirements under conditions of excessive data rates or over‐modulation. All inputs to the modules are buffered through logic or microprocessor inputs. Refer to Schematics. Y 3 The modular transmitter must have its own power supply regulation. The Module uses the chip SV6266F with built-in power management components, the module rated power is DC 2.1-3.46V power, Refer to schematics. Y 4 The modular transmitter must comply with the antenna and transmission system requirements of §§15.203, 15.204(b) and 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 §15.203 is not applicable to modules but can apply to limited modular approvals under paragraph (b) of this section. The modular transmitter has a PCB antenna arrangement for Wi-Fi. Refer to external photo. Y Company: High-Flying Electronics Technology Co., Ltd.

Unless the transmitter module will be battery powered, it must comply with the AC line conducted requirements found in §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 §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 §15.31(i)). The modular transmitter is tested in a stand-alone configuration, i.e., the module is not be inside another device when testing. Please refer to setup photo. Y 6 The modular transmitter must be equipped with either a permanently affixed label or must be capable of electronically displaying its FCC identification number The device Uses a permanently affixed label, refer Label .when the module is installed inside a nother device, then the outside of the device into which the module is installed,this exterior label must use wording such as the following: “Contains Transmitter Module FCC ID: 2ACSVHF-LPD100 ” or “Contains FCC ID: 2ACSVHF-LPD100”. Y 7 The modular transmitter must comply with 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. Refer to manual Y 8 The modular transmitter must comply with any applicable RF exposure requirements in its final configuration. The EUT comply with RF exposure requirements § 2.1091.If the device built into a host as a portable usage, the RF exposure evaluation may be required as specified by§ 2.1093.
