March 26, 2015 To whom it may concern, Request for Permanent Confidentiality Under FCC Part 15 Certification FCC ID: TB7DXTOYS3209027A Request is hereby submitted by Shantou Chenghai Dongxin plastic Toys Co., Ltd to withhold permanently from public review certain portions of the app lication for equipment certification for the referenced FCC identifiers. This reques t 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 Dongxin plastic Toys Co., L td reser ves 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: T his information represents intellectual property of Shantou Chenghai Dongxin pla stic Toys Co., Ltd and it is subject to competition. We have invested considerable time and materials in research and development to produce the r eferenced product. Disclosure of the permanently confidential portions of this application to competitors would not only give them significant competitive advanta ges in developing similar products, but would also disclose successful implementation of unpublished, leading edge technology developed by us. I f you have questions or need further information, please contact the undersigned. Regards, [Signature] [Name] Xieli Cai [Title]Vic manager SHANTOU CHENGHAI DONGXIN PLASTIC TOYS CO., LTD

1 INTERTEK TESTING SERVICES Analysis Report The equipment under test (EUT) is a portable transmitter for a TOY RC 4X4 operating at 27.145 MHz. The EUT is powered by one 9.0V 6F22 size battery. For more detail information pls. refer to the user manual. Antenna Type: Integral antenna Antenna Gain: 0dBi The nominal conducted output power specified: -38.0dBm (+/- 3dB) The nominal radiated output power (e.r.p) specified: -40.15dBm (+/- 3dB) Modulation Type: Pulse modulation According to the KDB 447498: The worst-case peak radiated emission for the EUT is 56.6 dBμV/m at 3m in the frequency 27.145MHz The EIRP = [(FS*D) ^2 / 30] mW= -38.63dBm The ERP = EIRP – 2.15 = -40.78 dBm which is within the production variation. The maximun conducted output power specified is -35dBm =0.0003mW The source- based time-averaging conducted output power = 0.0003* Duty Cycle mW < 0.1mW (Duty Cycle<100%) The SAR Exclusion Threshold Level for 27.145MHz when the minimum test separation distance is < 50mm: = 474 * [1 + log(100/f(MHz)]/2 = 371.2 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. Transmitter Duty Cycle Calculation The duration of one cycle = 18.9565ms Effective period of the cycle = 521.7μs x 10 + 1.5652 ms x 4 = 11.4778ms DC = 11.4778ms / 18.9565ms = 0.6055 or 60.55% FCC ID: TB7DXTOYS3209027A
