Shenzhen Huadoo Bright Group Limited Date: 7 January, 2015 To : Federal Communications Commission, Authorization & Evaluation Division, 7435 Oakland Mills Road, Columbia, MD 21046 To Whom It May Concern: The Shenzhen Huadoo Bright Group Limited, the undersigned, hereby authorizes Mr. Wu Xuewen from Shenzhen BALUN Technology Co.,Ltd., to act on the behalf of the Shenzhen Huadoo Bright Group Limited solely in matters relating to the application for an FCC equipment authorization for FCC ID # 2ACXS-V4 including the signing of documents in connection with this Application. Necessary acts carried out by Shenzhen BALUN Technology Co., Ltd. on our behalf of the Shenzhen Huadoo Bright Group Limited in connection with the Application shall have the same effect as acts of the Shenzhen Huadoo Bright Group Limited. The Shenzhen Huadoo Bright Group Limited also hereby certify that no party to this application is subject to a denial of benefits, including FCC benefits, pursuant to Section 5301 of the Anti-Drug Abuse Act of 1988, 21 U.S.C. 853(a). Thank you for your attention to this matter. Yours Sincerely, Terry Yuan [email protected] Shenzhen Huadoo Bright Group Limited

Shenzhen Huadoo Bright Group Limited Date: 14 Oct, 2014 To: Federal Communications Commission, Authorization & Evaluation Division, 7435 Oakland Mills Road, Columbia, MD 21046 Re: Shenzhen Huadoo Bright Group Limited FCC ID: 2ACXS-V4 FCC Certification Confidentiality Request Gentlemen: This letter is to comply with 47 CFR 0.457 and 0.459 pertaining to confidentiality material. Shenzhen Huadoo Bright Group Limited requests that the following documents regarding this submission for FCC ID: 2ACXS-V4 be kept confidential: Exhibit Type File Name Block Diagram Block Diagram.pdf Schematics Circuit Diagram.pdf Operational Description circuit description for fcc.pdf Part list BOM.pdf Tune-Up-Procedure Tune up procedure.pdf Those documents contain detailed system and equipment description and related information about the product which Shenzhen Huadoo Bright Group Limited considers to be confidential proprietary, a custom design and, otherwise, not releasable to the general public. Since this design is a basis form which future technological products will evolve, Shenzhen Huadoo Bright Group Limited considers this information would be of benefit to its competitors, and that the disclosure of the information in these documents would give competitors an unfair advantage in the market. Yours Sincerely, Terry Yuan [email protected] Shenzhen Huadoo Bright Group Limited

Date: January 7, 2015 Equipment Authorization Division Office of Engineering and Technology Federal Communications Commission 7435 Oakland Mills Road Columbia, MD 21046 Ref: FCC ID: 2ACXS-V4 label location justification Gentlemen: Shenzhen Huadoo Bright Group Limited requests acceptance of the labeling proposal described below for Smart Phone bearing FCC identifier 2ACXS-V3 The subject Smart Phone are compact handheld models as shown in figure 1, authorized under 47CFR Part 22H&24E for mobile services. Figure 1 Because the majority of the cell phone housing is composed of display, speaker, operating controls and a removable battery pack, there is extremely limited space available to attach the required label carrying the FCC identifier. Attaching the label to the battery pack is not acceptable because the battery pack is a removable item. For this reason, Shenzhen Huadoo Bright Group Limited proposes placing the label carrying the FCC identifier inside the battery compartment as shown in figure 2. Figure 2 The consumer packaging for these models includes the battery pack as a separate item, NOT installed on the radio. As such, the FCC identifier will be readily visible to the user before the battery pack is installed and whenever the battery pack is removed or replaced. In this location, the label will also be protected from physical abuse and remain readable for the anticipated life of the device. The consumer packaging for these models is a "gift box" which does not allow the transceiver to be seen at time of purchase. In order to meet the requirements of 47CFR Part 2.925 (d), Infinity System S.L. will add the FCC identifier "2ACXS-V4 " to the outside of the consumer "gift box" packaging. Thank you for your attention to this matter. Yours Sincerely, Wu Xuewen Certification manager Shenzhen BALUN Technology Co., Ltd.
