Hui Zhou Gaoshengda Technology Co.,LTD FCC Modular Approval Request To the FCC or FCC TCB handling this application Hereby we, Company name (grantee): Hui Zhou Gaoshengda Technology Co..LTD Address: NO.75 Zhongkai Development Area City / ZIP / State / Country: _Huizhou, Guangdong, China Request modular approval for the certification of our equipment within this application, identified by: FCC ID: 2AC23—WC6PA2201 The table below contains the justification for modular approval of this equipment: Requirement Explanation from grantee (do not write yes / no, but explain why it complies / how it is achieved) 1. The modular transmitter must have its own RF shielding. Yes (The modular equip with own RF shielding case) 2. The modular transmitter must have buffered modulation/ data inputs (if such Yes inputs are provided) to ensure that the module will comply with Part 15 (The modular data inputs are requirements under conditions of excessive data rates or over—modulation. buffered through log or micro—controller connections) 3. The modular transmitter must have its own power supply regulation. Yes (RF voltage regulation is handled on the module) 4. The modular transmitter must comply with the antenna requirements of Yes Section 15.203 and 15.204(c). The antenna must either be permanently (The modular with permanently attached or employ a "unique" antenna coupler (at all connections between the antenna, the antenna is PIFA module and the antenna, including the cable) Antenna) 5. The modular transmitter must be tested in a stand—alone configuration, i.e., Yes the module must not be inside another device during testing. This is intended to (The module was tested demonstrate that the module is capable of complying with Part 15 emission stand—alone) limits regardless of the device into which it is eventually installed 6. The modular transmitter must be labeled with its own FCC ID number, and, if Yes the FCC ID is not visible when the module is installed inside another device, (Please refer to FCC 1D label) 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 follewing: "Contains Transmitter Module FCC TD: XYZMODEL1" or "Contains FCC ID: XYZMODEL1.”4Any similar wording that expresses the same meaning may be used. The Grantee may either provide

Hui Zhou Gaoshengda Technology Co.,LTD 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 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 Yes requirements applicable to the transmitter and the manufacturer must provide (Please refer to the modular adequate instructions along with the module to explain any such requirements. installation manual) 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. 8. The modular transmitter must comply with any applicable RF exposure Yes requirements. For example, FCC Rules in Sections 2.1091, 2.1093 and specific (Please see the MPE report, the Sections of Part 15, including 15.319(i), 15.407(f), 15.253(f) and 15.255(g), modular meets MPE calculation require that Unlicensed PCS, UNII and millimeter wave devices perform routine of 47 CFR 1.107 (b)(1).) 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). 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.
