(3) Country code selection ability -

Yes , No If no, pls explain how it was implemented :

(4) Meet 15.202 requirement -

Yes , No , pls check below :

A master device is defined as a device operating in a mode in which it has the capability to transmit without receiving an enabling signal. In this mode it is able to select a channel and initiate a network by sending enabling signals to other devices A client device is defined as a device operating in a mode in which the transmissions of the device are under control of the master. A device in client mode is not able to initiate a network.

(5) For client devices that have software configuration control to operate in different modes (active scanning in some and passive scanning in others) in different bands (devices with multiple equipment classes or those that operate on non-

DFS frequencies) or modular devices which configure the modes of operations through software, the application must provide software and operations description on how the software and / or hardware is implemented to ensure that proper operations modes can not be modified by end user or an installer. Apply , No Apply , (If apply , pls help to provide explanation on it was implement , and how software was controlled) Signature :

Rajant Corporation Declaration of the Modular Approval Applicant / Grantee Rajant Corporation FCC ID: VJA-RJ2002

|Model: sd RJ-2002 The single module transmitter has been evaluated then tested meeting the requirements under Part 15C Section 2.12 as below:

YES EUT Condition Modular approval requirement

(a) 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, EUT is meeting this requirement 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, The module buffers modulation and inputs using Network processor system-on-chip. Kindly refer to the schematic diagram. Yes, the module uses DC-DC converter and Low Drop-out regulator for power supply regulation. Kindly refer to the schematic diagram. The modular transmitter must have its own power||supply regulation.

(c)

(d) The modular transmitter must comply with the antenna and_ transmission system requirements of Sections 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 Section 15.203 is not applicable to modules but can apply to limited modular approvals under paragraph (b) of this section. Yes, EUT is meeting this requirement

(e) The modular transmitter must be tested in a stand-alone configuration, i.e., the module must not be inside another device Yes, EUT is meeting this requirement Rajant Corporation 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 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)) must not be inside another device during testing.

(f) The modular transmitter must be equipped with either a permanently affixed label or must be capable of electronically displaying its FCC identification number. Yes, EUT is meeting this requirement 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 requirements, which are based on the intended use/configurations. Yes, EUT is meeting this requirement

(h) The modular transmitter must comply with any applicable RF exposure requirements in its final configuration. Yes, EUT is meeting this requirement Rajant Corporation Dated 6/14/2022 David Schena Signature Printed Name Title: VP Finance On behalf of: Rajant Corporation Telephone: 484-595-0233 Extension:220
