Re: Request for confidentiality Applicant: Hand and Nail Harmony. Inc FCC ID: [] To whom it may concern, Permanent Confidentiality Request is hereby submitted by Hand and Nail Harmony. Inc to withhold permanently from public review certain portions of the application for equipment certification for the referenced FCC identifiers. This request for confidentiality is made pursuant to 47 CFR 0.457(d) and 0.459 of the FCC Rules. In particular, the following sections of the application are to be kept permanently confidential: x Schematics x Detailed Block diagrams x Detailed Operational/Functional Description Short-term Confidentiality Request is hereby submitted by Hand and Nail Harmony. Inc to withhold from public review for a period of 45 days from the date of the Grant of Equipment Authorization and prior to marketing, certain portions of the application for equipment certification for the referenced FCC identifiers. This request for confidentiality is made pursuant to 47 CFR 0.457(d) and 0.459 of the FCC Rules. In particular, the following sections of the application are to be kept confidential for a period of 45 days from the date of Authorization: x External photos x Internal photos x User manual 2AG7O-GELISHMTSPK Senior Manager Rationale for request for confidentiality: Hand and Nail Harmony. Inc has invested considerable time and materials in research and development to produce the referenced product. Permanent confidentiality: Disclosure of the permanently confidential portions of this application to competitors would not only give them significant competitive advantages in developing similar products, but would also disclose successful implementation of unpublished, leading edge technology developed by us. Short term confidentiality: Disclosure of the short-term confidential portions of this application during the period of importation and/or distribution would reveal key aspects of proprietary technology to competitors and diminish the value of our investment in research and development. If you have questions or need further information, please contact the undersigned. Sincerely, Hand and Nail Harmony. Inc

INTERTEK TESTING SERVICES RF Exposure The equipment under test (EUT) is a Wireless Speaker with Bluetooth function. The EUT was powered by the fully-charged DC 3.7V, 400mAh new rechargeable battery which was charged by USB port (DC 5V). For more detail information pls. refer to the user manual. Modulation Type: GFSK, π/4DQPSK, 8DPSK. Blu etooth Version: 2.1 with EDR. Antenna Type: Integral antenna. Antenna Gain: 2.1dBi. The nominal conducted output power specified: -12.0dBm +/-3dB. T he nominal radiated output power (e.i.r.p) specified: -9.9dBm (+/- 3dB) Acco rding to the KDB 447498: The maximun peak radiated emission for the EUT is 85.2dBV/m at 3m in the frequency 2441MHz The EIRP = [(FS*D) ^2 / 30] mW = -10.0dBm which is within the production variation. The minimum peak radiated emission for the EUT is 84.2d BV/m at 3m in the frequency 2480MHz The EIRP = [(FS*D) ^2 / 30] mW = -11.0dBm which is within the production variation. The maximun conducted output power specified is -9.0dB m = 0.126mW Th e source- based time-averaging conducted output power = 0.126 * Duty Cycle mW (where Duty Cycle<100%) < 0.126 mW Th e SAR Exclusion Threshold Level: = 3. 0 * (min. test separation distance, mm) / sqrt(freq. in GHz) = 3.0 * 5 / sqrt (2.480) mW = 9.5 mW Since the source-based time-averaging conducted output power is well below the SAR low threshold level, so the EUT is considered to comply with SAR requirement without testing.
