Date: November 11, 2015 To whom it may concern, Request for Permanent Confidentiality Under FCC Part 15 Certification FCC ID: PKU-SX123-00 Request is hereby submitted by SHANTOU CHENGHAI SHUANGXING TOYS CO. LTD, 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 and SHANTOU CHENGHAI SHUANGXING TOYS CO. LTD, reserves the right to discern which parties can obtain access to these information: Schematics Detailed Block diagrams Detailed Operational/Functional Description The rationale for request for confidentiality is as followings: This information represents intellectual property of SHANTOU CHENGHAI SHUANGXING TOYS CO. LTD, and it is subject to competition. We have invested considerable time and materials in research and development to produce the referenced product. 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significant competitive advantages in developing similar products, but would also disclose successful implementation of unpublished, leading edge technology developed by us. If you have questions or need further information, please contact the undersigned.

1 INTERTEK TESTING SERVICES RF Exposure The Equipment under Test (EUT) is a Car unit for Remote Control Car Series model: 1136A operating at 2.4GHz band. It is powered by DC 9.0V (6 x 1.5V AA batteries).For more detail information pls. refer to the user manual. Antenna Type: Monopole antenna. Antenna Gain: 0dBi. The normal radiated output power (e.i.r.p) is: -12.4dBm (tolerance: +/- 3dB). The normal conducted output power is: -12.4dBm (tolerance: +/- 3dB). Modulation Type: GFSK. According to the KDB 447498: T he Maximum peak radiated emission for the EUT is 85.5dBμV/m at 3m in th e frequency 2480MHz The EIRP = [(FS*D) ^2 / 30] mW = -9.7dBm which is within the production variation. The Minimum peak radiated emission for the EUT is 80.1dBμV/m at 3m in th e frequency 2402MHz The EIRP = [(FS*D) ^2 / 30] mW = -15.1dBm which is within the production variation. The maximum conducted output power specified is -9.4d Bm = 0.1mW The source- based time-averaging conducted output power = 0.1* Duty cycle mW <0.1 mW(Duty cycle <100%) T he SAR Exclusion Threshold Level: = 3.0 * (min. test separation distance, mm) / sqrt(freq. in GHz) = 3.0 * 5 / sqrt (2.480) mW = 9.5mW 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. The duty cycle is simply the on-time divided by the period: The duration of one cycle = 8.8261ms Effective period of the cycle = 2.5652ms x 1=2.5652ms Duty Cycle = 2.5652ms / 8.8261ms =29.06% FCC ID: PKU-SX123-00
