The module transmitter will be a limited module Modular Approval Request FCC (Per 15.212) FCC ID: 2AR82-SKIWB7638U2 Items to be coveredAnswer From Applicant 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. Yes 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. Yes 3. The modular transmitter must have its own power supply regulation.Yes 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. Yes 5. The modular transmitter must be tested in a stand-alone configuration,i.e., the module must not be inside another device during testing for compliance with part 15 requirements. 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)). No The modular transmitter is not stand- alone, BT antenna connector and related matching circuit are located in the host circuit board. 6. The modular transmitter must be equipped with either a permanently affixed label or 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: XYZMODEL1” or “Contains FCC ID: XYZMODEL1.” Any similar wording that expresses the same meaning Yes maybeused.TheGranteemayeitherprovidesuchalabel,anexample ofwhichmustbeincludedintheapplicationforequipmentauthorization, or,mustprovideadequateinstructionsalongwiththemodulewhich explainthisrequirement.Inthelattercase,acopyoftheseinstructions mustbeincludedintheapplicationforequipmentauthorization.
