Hui Zhou Gaoshengda fechnology Co.,LTD years rCC To the FCC or FCC CB handling this application Hereby we, Company naine (grantee): Hui Zhou Gaoshengda Technology Co.,LTD Address: NO.2 Huaxing RD, Zhongkai Development Area City / ZIP / State / Country: Huizhou, Guangdong, China Viodular Approval Request Request modular approval for the certification of our equipment within this application, identified by:

FCC ID: 2AC23-W2GT The table below contains the justification for modular approval of this equipment:

Requirement 1. The modular transmitter must have 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 over-modulation. Explanation from grantee (do not write yes / no, but explain why it complies / how it is achieved) Yes

(The modular equip with own RF shielding case) Yes

(The modular data inputs are buffered through log or micro-

controller connections) 3. The moduler transmitter must have its own power supply regulation. 4. The modular transmitter must comply with the antenna requirements of Section 15.203 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) 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 6. The modular transmitter must be labeled with its own FCC ID number, and, ifthe 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

(Please refer to FCC ID label) Hui Zhou Gaoshengda Technology Co.,LTD such a label, an exemple of which must be included in the application for eauipment authorization, or, must provide adequate instructions along with the |

-moduie 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. | insialiation manual) A copy of these instructions must be included in the application for equipment authorization. For example, there are very sirict 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 (Please see the MPE report, the specific Sections of Part 15, including 15.319(i), 15.407(f), 15.253(f) and modular meets MPE calculation 15.255(g), require that Unlicensed PCS, UNII and millimeter wave devices of 47 CFR 1.107 (b)(1).) 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). 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.
