Date: April 20, 2015 To whom it may concern, Request for Permanent Confidentiality Under FCC Part 15 Certification FCC ID: PKG12120RC27A Request is hereby submitted by May Cheong Toy products FTY. 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 May Cheong Toy products FTY. 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 May Cheong Toy products FTY. 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significant competitive advantages in developing similar products, but would also disclose successful implementation of unpublished, leading edge technology developed by us.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. Regards, Signature: Name: Anson Wang Title: Quality Manager

1 INTERTEK TESTING SERVICES Analysis Report The equipment under test (EUT) is a portable transmitter for a RADIO CONTROL VEHICLE R/C ROCK CRAWLER, ASSORTED operating at 27.145MHz. The EUT is powered by two 1.5V AAA size batteries. For more detail information pls. refer to the user manual. Antenna Type: Integral antenna Antenna Gain: 0dBi The nominal conducted output power specified: -25.0dBm (+/- 3dB) The nominal radiated output power (e.r.p) specified: -27.15dBm (+/- 3dB) Modulation Type: Pulse modulation According to the KDB 447498: The worst-case peak radiated emission for the EUT is 69.6dBμV/m at 3m in the frequency 27.145MHz The EIRP = [(FS*D) ^2 / 30] mW= -25.63dBm The ERP = EIRP – 2.15 = -27.78 dBm which is within the production variation. The maximun conducted output power specified is -22dBm = 0.006mW The source- based time-averaging conducted output power = 0.006* Duty Cycle mW < 0.1mW (Duty Cycle<100%) T he 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 = 88.841ms Effective period of the cycle = 0.2464ms x 4 + 0.3913ms x 1 + 0.1594ms x 11=3.1303ms DC = 3.1303ms / 88.841ms = 0.0352 or 3.52% FC C ID: PKG12120RC27A
