CORAL-TAIYI CO., LTD. Modular Approval Request FCC (KDB 996369 D01 & Part 15.212) FCC ID: 2A7B5-LGA Items to be covered by Single modular transmitters. Answer from applicant 1. The modular transmitter must have its own RF shielding. Yes, The EUT provides the 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 over- modulation. The EUT has its buffered modulation. Please see the Schematic Diagram. 3. The modular transmitter must have its own power supply regulation. The EUT has its own power supply regulation. Please see the Schematic Dia gram. 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, including the cable). The EUT meets the FCC antenna requirements; permanently attached antenna Please refer to photo of antenna are shown in the test report. 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 eventuall y installed. The EUT was testes 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). Please see exhibition label sample for the FCC ID of this module. And also in the exhibition Users manual, there are instructions gives to the OEM on how to label the end product 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. The EUT is compliant 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. The EUT is compliant with RF exposure requirement. RF exposure is addressed in the RF exposure exhibition. Note: A limited modular approval (LMA) may be granted for single or split modular transmitters that comply partially with the requirements above.
