Modular Approval Request FCC (KDB 996369 D01 & Part 15.212) FCC ID: R4UARCRFM2400RX Items to be covered by modular transmitters. Y/NAnswer from applicant 1. The modular transmitter must have its own RF shielding. Yes The module contains its own RF shielding. 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 ove r-modulation. Yes The module’s transmitter chip utilizes buffered data inputs. 3. The modular transmitter must have its own power supply regulation. Yes The module contains its own power supply re gulatoron U1 (S-1333A33-M5T1U3). 4. The modular transmitter must comply with the antenna requirements of Section 15.203 and 15.204(b)(c). The antenna must either be permanently attached or employ a “unique” antenna coupler (at all connections between the module and the antenna, includin g the cable). Yes The module uses permanently attached antenna that meets the requirements. 5. The modular transmitter must be tested in a stand-alone configuration, i.e., the module must not be inside another device during testing. This is intended to demonstrate that the module is capable of complying with Part 15 emission limits regardless of the device into which it is eventually installed. Yes The module is tested in a stand-alone configuration. Please see section photographs of test configuration in the test report. 6. The modular transmitter must be equipped with either a permanently affixed label or must be capable of electronically displaying its FCC identification number in accordance with 15.212 (a)(1)(vi)(A) / (B). Yes Please see exhibition label sample for the FCC ID of this module. The user’s manual instructs the integrators on how to label the en dproduct. 7. The modular transmitter must comply with any specific rule or operating requirements applicable to the 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. For example, there are very strict operational and timing requirements that must be met before a transmitter is authorized for operation under Section 15.231. For instance, data transmission is prohibited, except for operation under Section 15.231(e), in which case there are separate field strength level and timing requirements. Compliance with these requirements must be assured. Yes The module complies with all applicable FCC rules. Details instructions for maintaining compliance are given in the User Manual. 8. The modular transmitter must comply with any applicable RF exposure requirements. For example, FCC Rules in Sections 1.1310, 2.1091, 2.1093, and specific Sections of Part 15, including 15.319(i), 15.407(f), 15.253(f) and 15.255(g), require that Unlicensed PCS, UNII and millimeter wave devices perform routine environmental evaluation for RF Exposure to demonstrate compliance. In addition, spread spectrum transmitters operating under Section 15.247 are required to address RF Exposure compliance. Modular transmitters approved under other Sections of Part 15, when necessary, may also need to address certain RF Exposure concerns, typically by providing specific installation and operating instructions for users, installers and other interested parties to ensure compliance. Yes The module complies with RF exposure requirements. Evaluation is addressed in the RF exposure information exhibition. Note: A limited modular approval (LMA) may be granted for single or split modular transmitters that comply partially with the requirements above. Name and surname of applicant (or authorized representative): Signature: Date:August 29, 2024 Name: Jim Chang Title: RF Manager

1 STATEMENT The label is affixed on an immovable part of the front side of the device. There is no space to bear Part 15.19 statement due to the size of the device is smaller than a palm, the statement is specified in user manual. 2 LABEL LOCATION
