2AJE9MR-2400MBWireless transceiver unit

IM-A-1457 July 2023 User’s manual The module is only approved for use by the grantee in its own products and not intended for sale to third parties. T he user manual for integration instructions are internal confidential manufacturing documents. For the details about this module, please refer to the specification sheet of the module. This module should be installed in the host device according to the interface specification (installation procedure). Identifier marking for 2.4GHz band RF SiP MR-2400MB modules The module is a Surface Mount Device SiP (System in Package) soldered onto the end product and is not accessible to the end-user. It is not possible for the end-user to replace or remove the module. The outline size is 6.5 x 6.5 mm. The identification marking is made by sticker (see Figure- 1): - Readable module name - Company Logo The size of the marking area is only 4.0 x 6.0 mm, thus the size of the module/label makes it impossible to print the FCC and IC IDs on the identifier label in a print size of 4 points or larger. Instead the FCC, CE-Red, MIC and NCC IDs are printed on the cardboard box as well as the modules user manual of the end devices. Figure-1 MR-2400MB with identifier marking. This device complies with radio regulations of below countries and region. 1) Regulatory information for Japan Radio Law The MR-2400MB module comply with the Japanese Technical Regulation Conformity Certification of Specified Radio Equipment (ordinance of MPT No. 37, 1981), Article 2, Paragraph 1: Item 19 "2.4 GHz band wide band low power data communication system". End products based on MR-2400MB module and targeted for distribution in Japan must be affixed with a label with the “Giteki” marking or certification number. The marking or certification number must be visible for inspection. Also, the following statements must be described on the user manual of the host device of this module; 本製品は，電波法に基づく小電力データ通信システムの無線局の無線設備（技術基準 適合認定：証明規則第2条第1項第19号）として，認証を受けています。 従って，本製品を使用するときに無線局の免許は必要ありません。 ただし，以下の事項を行うと法律で罰せられることがあります。 ・本製品を分解／改造すること ・本製品に貼ってある証明ラベルをはがすこと 機器名称：MR-2400MB 工事設計認証番号：007-AM0009 Statement translation: The product has been certified as a low-power data communications system in the 2.4 GHz band (Technical Regulations Conformity Certification System: Ordinance of MPT No. 37, 1981, Article 2, paragraph 1, item (19)) according to the Radio Law of Japan. Accordingly, no radio equipment license is required to use this product. However, the following actions may be punishable under law: • Disassembling or modifying the product. • Removing the certification label on the product. Name of radio equipment: MR-2400MB Number of type certification: 007-AM0009 * If it is difficult to describe this statement on the host product due to the size, please describe it in the User's manual. The auxiliary label will have at least the information shown in the figure below: Figure-2 MR-2400MB auxiliary label for Japan Radio Low AM0009 2) Regulatory information for FCC(U.S.A.) The MR-2400MB module is FCC authorized for the specific rule parts (i.e., FCC transmitter rules) listed on the grant, and the host product manufacturer is responsible for compliance to any other FCC rules that apply to the host not covered by the modular transmitter grant of certification. The final host product still requires Part 15 Subpart C compliance testing with the modular transmitter installed. Fine tuning of return loss etc. can be performed using a matching network. However, it is required to check "Class1 change" and "Class2 change" which the authorities define then. The following information must be indicated on the host device of this module; Contains Transmitter Module FCC ID: 2AJE9MR-2400MB or Contains FCC ID: 2AJE9MR-2400MB This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. * If it is difficult to describe this statement on the host product due to the size, please describe in the User's manual. The following statements must be described on the user manual of the host device of this module; FCC CAUTION Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. This transmitter must not be co-located or operated in conjunction with any other antenna or transmitter. This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment and meets the FCC radio frequency (RF) Exposure Guidelines. This equipment is not certified as type of the portable device with FCC Rules. Then, please use within specification of this product and have a separation distance of minimum 20 mm between the user and/or bystander and the antenna and /or radiating element. Digital devices used EXCLUSIVELY as industrial, commercial or medical test equipment. "Test equipment" includes devices used for maintenance, research, evaluation, simulation and other analytical or scientific applications in areas such as industrial plants, public utilities, hospitals, universities, laboratories, automotive service centers and electronic repair shops. If the final host is installed at the areas that are not subject to 15.103(c) exempted devices from Part 15 subpart B, it requires Part 15 Subpart B compliance testing. FCC standards: FCC CFR Title 47 Part 15 Subpart C Section 15.247 The devices must be installed and used in strict accordance with the manufacturer's instructions as described in the user documentation that comes with the product."
