Modular Approval Request Applicant: MULTI TECH SYSTEMS INC FCC ID: AU792U22C01871 4/6/22 To Whom It May Concern:
Pursuant to Section 15.212(a)(1) of the FCC rules, the Applicant, request for single modular approval, compliance with the requirements are addressed below. Single Modular Approval Requirements Justification
(i) 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. The module has no shielding case. Any host device using this limited modular approved radio shall be tested for compliance with transmitter spurious radiated emission limits
(ii) The modular transmitter must have buffered modulation/data All modulation and data input (s) are buffered 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.
(iii) The modular transmitter must have its own power supply The BLE chip has its own embedded power regulation. management circuit, support wide power supply voltage 1.71V to 3.8V
(iv) The modular transmitter must comply with the antenna and The module has an on-board PCB antenna 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.
(v) The modular transmitter must be tested in a stand-alone The modular transmitter was tested in a configuration, i.e., the module must not be inside another stand-alone configuration and it is complied device during testing for compliance with part 15 with the AC line conducted requirement 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)).
(vi) The modular transmitter must be equipped with either a The module will be equipped with a permanently affixed label or must be capable of electronically permanently affixed label. displaying its FCC identification number. The module is installed inside another device
(A) If using a permanently affixed label, the modular and outside of the device, into which the transmitter must be labeled with its own FCC identification module is installed, will be labelled with all number, and, if the FCC identification number is not visible necessary contains wording and FCC/IC when the module is installed inside another device, then the numbers 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 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. 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.
(vii) The modular transmitter must comply with any specific rules Yes, refer to the user manual
(viii) The modular transmitter must comply with any applicable RF Yes, refer to the RF exposure evaluation test exposure requirements in its final configuration. report Sincerely, Signature Name: Tracey Dickinson Title: VP of Program Management and Continuous Improvement Date: 4/6/22
