PAGE 1 OF 4 Version 1.0 Hui Zhou Gaoshengda Technology Co., LTD W37M2510 FCC Statement This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

-Reorient or relocate the receiving antenna.

-Increase the separation between the equipment and receiver.

-Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

-Consult the dealer or an experienced radio/TV technician for help. This equipment complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:

(1) This device may not cause harmful interference, and

(2) This device must accept any interference received, including interference that may cause undesired operation. Any changes or modifications not expressly approved by the party responsible for compliance could void the users authority to operate the equipment. Please notice that if the FCC identification number 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 FCC ID:2AC23-W37Or Contains Transmitter Module FCC ID:2AC23-W37any similar wording that expresses the same meaning may be used. This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of 20cm between the radiator & your body. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.

- Information on test modes and additional testing requirements Any final host product with the modular transmitter installed should be under test according to guidance given in KDB 996369 D04. To enter test mode for module, MT7603 QA V0.0.185 software and command is necessary. When something wrong happens in configuring test modes for host product with module, host product manufacturer should coordinate with module manufacturer for technical support. It is recommended that some investigative measurements should be taken to confirm that host product with module installed does not exceed the spurious emissions limits or band edge limits.

To Whom It May Concern:

Hui Zhou Gaoshengda Technology Co.,LTD Here by apply for Class II Permission Change to the approved product under FCC ID: 2AC23-W37, to mobile category when applied in the WIFI Module due to the design of the platform resulting in greater than 20 cm distance to human body. Radiated emission testing was additionally performed due to the following:

The product with FCC ID: 2AC23-W37 module was assessed compliant to radiated emission limits per 15.247 in its initial FCC approval. The antenna is designed for a higher peak gain and a lower peak gain in the intentional transmit frequency bands and therefore radiated performance in the intentional frequency bands and the spurious emissions out of bands are needed to be tested. Please kindly review the application documents submitted and grant approval for this Permissive Change application. Sincerely yours, ________________________

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-W37 The table below contains the justification for modular approval of this equipment:

O Requirement Explanation from grantee (d 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 Integral 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

(Please refer to FCC ID label) 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:

XYZMODEL1 or Contains FCC ID: XYZMODEL1. Any 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 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 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

(Please see the MPE report, the modular meets MPE calculation 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.
