Requirement of FCC KDB99369 – Modular Approval Requirement Comply（Y/N） 1. The modular transmitter must have its own RF shielding. Y - The EUT provides the RF shielding. See EUT photo. 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. Y - The EUT has its buffered modulation. Please see the Schematic Diagram. 3. The modular transmitter must have its own power supply regulation. Y - The EUT has its own power supply regulation, please see the Schematic Diagram. 4. 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. Y - The EUT meets the FCC antenna requirements; unique antenna connector and 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. Y - The EUT was tested with a test cable, see test report and setup photo 6. The modular transmitter must be labelled with its own FCC ID number, and, if the FCC ID is not visible when the module is installed inside another device, then the 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: 2ADLE-900X” or “Contains FCC ID: 2ADLE-900X” 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 Y - Please see exhibition label sample for the FCC ID of this module. And also in the exhibition User’s manual, there are instructions to the OEM on how to label the end product. Gree Electric Appliances, Inc. of Zhuhai requirement. In the latter case, a copy of these instructions must be included in the application for equipment authorization. 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. Y - The EUT is compliant with all applicable FCC rules. Details instructions for maintaining compliance are in the User Manual. 8. The modular transmitter must comply with any applicable RF exposure requirements. For example, FCC Rules in Sections 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 in accordance with Section 15.247(b)(4). Y - The EUT complies with RF exposure requirement. Sincerely, Name (Printed): Linda Li Title: - Signature: On behalf of Company: Gree Electric Appliances, Inc. of Zhuhai

Software Security Description Applicant describe the overall security measures implemented in the device that ensure that the device cannot be modified by any RF-related software changes by third parties to operate outside the authorized RF parameters without further approval from the FCC/ISED The description of the RF-related software must address the following questions in the operational description for the device and clearly demonstrate how the device meets the RF-security requirements. SOFTWARE SECURITY DESCRIPTION Description 1. Describe how any software/firmware updates for elements than can affect the device’s RF parameters will be obtained, downloaded, validated and installed. For software that is accessed through manufacturer’s website or device’s management system, describe the different levels of security as appropriate. Any new software/firmware only can be install by professionals. 2. Describe the RF parameters that are modified by any software/firmware without any hardware changes. Are these parameters in some way limited such that any other software/firmware changes will not allow the device to exceed the authorized RF characteristics? There are no any interfaces inside the software/firmware to modify the radio frequency parameters. 3. Describe in detail the authentication protocols that are in place to ensure that the source of the RF-related software/firmware is valid. Describe in detail how the RF- related software is protected against modification. There is a qualified database for software revision control inside and no interface outside to modify RF character. 4. Describe in detail any encryption methods used to support the use of legitimate RF- related software/firmware. Any software/firmware modification will have the verification procedure and verification results and release letter and impact analysis report based on QMS process. Any modification will be highlighted on the release letter, and the impact analysis will also have a review. Verification procedure and verification results will be performed based on the release letter and impact analysis report. Encryption methods: WPA/WPA2/WPA3,AES_ECB 5. For a device that can be configured as a master and client (with active or passive scanning), explain how the device ensures compliance for each mode? In particular if the device acts as master in some band of operation and client in another; how is compliance ensured in each band of operation? The device that can not be configured as a master in 5GHz band Third-Party Access Control 1. Explain if any third parties have the capability to operate a U.S.-sold device on any other regulatory domain, frequencies, or in any manner that may allow the device to operate in violation of the device’s authorization if activated in the U.S. No, the device not permits operates in violation of the device’s authorization. 2. Describe, if the device permits third-party software or firmware installation, what mechanisms are provided by the manufacturer to permit integration of such functions while ensuring that the RF parameters of the device cannot be operated outside its authorization for operation in the U.S. In the description include what controls and/or agreements are in place with providers of third-party functionality to ensure the devices’ underlying RF parameters are unchanged and how the manufacturer verifies the functionality. No, the device not permits third-party software or firmware installation. 3. For Certified Transmitter modular devices, describe how the module grantee ensures that host manufacturers fully comply with these software security requirements for U- NII devices. If the module is controlled through driver software loaded in the host, describe how the drivers are controlled and managed such that the modular transmitter RF parameters are not modified outside the grant of authorization. The RF parameters are controlled by the driver software loaded into the host,and the channel configuration information is solidified in the program and cannot be modified by the user.

If different levels of access are permitted for professional installers, system integrators or end-users, describe the differences. a What parameters are viewable and configurable by different parties? No any parameters are viewable and configurable by different parties b What parameters are accessible or modifiable by the professional installer or system integrators? 1) Are the parameters in some way limited, so that the installers will not enter parameters that exceed those authorized? The device not permits operates in violation of the device’s authorization. 2) What controls exist that the user cannot operate the device outside its authorization in the U.S.? Any modification will be highlighted on the release letter, and the impact analysis will also have a review. Verification procedure and verification results will be performed based on the release letter and impact analysis report. c What parameters are accessible or modifiable by the end-user? 1) Are the parameters in some way limited, so that the user or installers will not enter parameters that exceed those authorized? There are no any interfaces is the UI accessible. 2) What controls exist so that the user cannot operate the device outside its authorization in the U.S.?
