I certify that submitted documents properly describe the device or system for which equipment certification is sought. I also certify that each unit manufactured, imported or marketed, as defined in the FCC or Industry Canada’s regulations will have affixed to it a label identical to that submitted for approval with this application. For instances where our authorized agent signs the application for certification on our behalf, I acknowledge that all responsibility for complying with the terms and conditions for Certification, as specified by TUV Rheinland Group, still resides with Keen High Technologies Ltd. Block A1 & A2, Ze Da Li Industrial Park, Tangwei Area, Fuyong, Bao’an, Shenzhen, Guangdong Province, China For TCB applications, We certify that we are not subject to denial of federal benefits, that includes FCC benefits, pursuant to Section 5301 of the Anti-Drug Abuse Act of 1988, 21 U.S.C. 862. Further, no party, as defined in 47 CFR 1.2002 (b), to the application is subject to denial of federal benefits, that includes FCC benefits. Thank you, Agency Agreement Expiration Date: _____May 15,2015_____ By: __________________________ _________Alina.Wu_________________ (Signature) (Print name) Title: ___ Engineer _______ _____ Telephone:_____ 0755-88309222-8566____ On behalf of: __ Keen High Technologies Ltd._______ (Company Name)

Confidentiality Letter Date: May 15,2014 Subject: Confidentiality Request for FCC ID: XUZNS-15AT08 and IC ID: 10558A-NS15AT08 Pursuant to FCC 47 CRF 0.457(d) and 0.459 and IC RSP-100, Section 10, the applicant requests that a part of the subject FCC/IC application be held confidential. Type of Confidentiality Requested Exhibit Short Term Permanent Block Diagrams Short Term Permanent Internal Photos Short Term Permanent Operation Description/Theory of Operation Short Term Permanent Part List/Tune-Up Procedure Short Term Permanent Schematics Short Term Permanent User’s Manual ____ Keen High Technologies Ltd._____ has spent substantial effort in developing this product and it is one of the first of its kind in industry. Having the subject information easily available to "competition" would negate the advantage they have achieved by developing this product. Not protecting the details of the design will result in financial hardship. Permanent Confidentiality: The applicant requests the exhibits listed above as permanently confidential be permanently withheld from public review due to materials that contain trade secrets and proprietary information not customarily released to the public. Short-Term Confidentiality: The applicant requests the exhibits selected above as short term confidential be withheld from public view for a period of ___(specify number of days not to exceed 180 ) ___ days from the date of the Grant of Equipment Authorization and prior to marketing.
