INTERTEK TESTING SERVICES EXHIBIT 1 GENERAL DESCRIPTION FCC ID: PQN44319RX49 1

INTERTEK TESTING SERVICES 1.0 General Description 1.1 Product Description The equipment under test (EUT) is a receiver for a RC toy airplane operating at 49.860 MHz. The EUT is powered by internal 3.7V rechargeable Po-Li Battery. The EUT has an ON/OFF switch and a charge socket. It can be controlled to fly forward, turning left and right directions by the corresponding controller. The EUT can be charged when it connects with the corresponding controller. The brief circuit description is saved with filename: descri.pdf 1.2 Related Submittal(s) Grants This is a single application for certification of a receiver. The transmitter for this receiver is authorized by Certification procedure with FCC ID: PQN44319TX49. FCC ID: PQN44319RX49 2

INTERTEK TESTING SERVICES 1.3 Test Methodology The radiated emission measurements were performed according to the procedures in ANSI C63.4 (2003). All measurements were performed in Open Area Test Sites. Preliminary scans were performed in the Open Area Test Sites only to determine worst case modes. All Radiated tests were performed at an antenna to EUT distance of 3 meters, unless stated otherwise in the "Justification Section" of this Application. 1.4 Test Facility The open area test site and conducted measurement facility used to collect the emission data is located at Garment Centre, 576 Castle Peak Road, Kowloon, Hong Kong. This test facility and site measurement data have been fully placed on file with the FCC. FCC ID: PQN44319RX49 3

INTERTEK TESTING SERVICES EXHIBIT 2 SYSTEM TEST CONFIGURATION FCC ID: PQN44319RX49 4

INTERTEK TESTING SERVICES 2.0 System Test Configuration 2.1 Justification The system was configured for testing in a typical fashion (as a customer would normally use it), and in the confines as outlined in ANSI C63.4 (2003). The EUT was powered by a fully charged internal 3.7V rechargeable battery during test. For maximizing emissions, the EUT was rotated through 360°, the antenna height was varied from 1 meter to 4 meters above the ground plane, and the antenna polarization was changed. This step by step procedure for maximizing emissions led to the data reported in Exhibit 3.0. The unit was operated standalone and placed in the center of the turntable. The equipment under test (EUT) was configured for testing in a typical fashion (as a customer would normally use it). The EUT was placed on the turntable, which enabled the engineer to maximize emissions through its placement in the three orthogonal axes. 2.2 EUT Exercising Software There was no special software to exercise the device. 2.3 Special Accessories There are no special accessories necessary for compliance of this product. FCC ID: PQN44319RX49 5

INTERTEK TESTING SERVICES 2.4 Equipment Modification Any modifications installed previous to testing by Spin Master Toys Far East Ltd. will be incorporated in each production model sold/leased in the United States. No modifications were installed by Intertek Testing Services. 2.5 Measurement Uncertainty When determining the test conclusion, the measurement uncertainty of test has been considered. 2.6 Support Equipment List and Description This product was tested in a standalone configuration. All the items listed under section 2.0 of this report are Confirmed by: Chow Chi Ming, Billy Manager Intertek Testing Services Agent for Spin Master Toys Far East Ltd.

INTERTEK TESTING SERVICES EXHIBIT 3 EMISSION RESULTS FCC ID: PQN44319RX49 7

INTERTEK TESTING SERVICES 3.0 Emission Results Data is included worst case configuration (the configuration which resulted in the highest emission levels). A sample calculation, configuration photographs and data tables of the emissions are included. FCC ID: PQN44319RX49 8

INTERTEK TESTING SERVICES 3.1 Field Strength Calculation The field strength is calculated by adding the Antenna Factor and Cable Factor, and subtracting the Amplifier Gain (if any) from the measured reading. The basic equation with a sample calculation is as follows: FS = RA + AF + CF - AG where FS = Field Strength in dBμV/m RA = Receiver Amplitude (including preamplifier) in dBμV CF = Cable Attenuation Factor in dB AF = Antenna Factor in dB AG = Amplifier Gain in dB In the following table(s), the reading shown on the data table reflects the preamplifier gain. An example for the calculations in the following table is as follows: FS = RR + LF where FS = Field Strength in dBμV/m RR = RA - AG in dBμV LF = CF + AF in dB Assume a receiver reading of 52.0 dBμV is obtained. The antenna factor of 7.4 dB and cable factor of 1.6 dB are added. The amplifier gain of 29 dB is subtracted, giving a field strength of 32 dBμV/m. This value in dBμV/m was converted to its corresponding level in μV/m. RA = 52.0 dBμV/m AF = 7.4 dB RR = 23.0 dBμV CF = 1.6 dB LF = 9.0 dB AG = 29.0 dB FS = RR + LF FS = 23 + 9 = 32 dBμV/m Level in µV/m = Common Antilogarithm [(32 dBμV/m)/20] = 39.8 μV/m FCC ID: PQN44319RX49 9

INTERTEK TESTING SERVICES 8.0 Miscellaneous Information This miscellaneous information includes details of the stabilizing process (including a plot of the stabilized waveform) and the test procedure. FCC ID: PQN44319RX49 22

INTERTEK TESTING SERVICES 8.1 Stabilization Waveform Previous to the testing, the superregenerative receiver was stabilized as outlined in the test procedure. The plot saved on the filename : superreg.pdf shows the fundamental emission when a signal generator was used to stabilize the receiver. Please note that the antenna was placed as close as possible to the EUT for clear demonstration of the waveform and that accurate readings are not possible from this plot. FCC ID: PQN44319RX49 23

INTERTEK TESTING SERVICES 8.2 Emissions Test Procedures The following is a description of the test procedure used by Intertek Testing Services Hong Kong Ltd. in the measurements of superregenerative receivers operating under the Part 15, Subpart B rules. The test set-up and procedures described below are designed to meet the requirements of ANSI C63.4 - 2003. Superregenerative receivers are stabilized prior to measurement by generating a signal well above the receiver threshold whose frequency is tuned until the emissions stabilize into a line spectrum. The signal is usually generated as CW with a Marconi 2022D signal generator and a short whip antenna and is at a level of several hundred to several thousand mV/m. Plots of the stabilized signal will be shown. If a modulated signal is used, it will be noted. The equipment under test (EUT) is placed on a wooden turntable which is four feet in diameter and approximately one meter in height above the groundplane. During the radiated emissions test, the turntable is rotated and any cables leaving the EUT are manipulated to find the configuration resulting in maximum emissions. The antenna height and polarization are also varied during the testing to search for maximum signal levels. The height of the antenna is varied from one to four meters. Detector function for radiated emissions is in peak mode. Average readings, when required, are taken by measuring the duty cycle of the equipment under test and subtracting the corresponding amount in dB from the measured peak readings. The frequency range scanned is from 30 MHz to 1000 MHz. FCC ID: PQN44319RX49 24

INTERTEK TESTING SERVICES 8.2 Emissions Test Procedures (cont’d) The EUT is warmed up for 15 minutes prior to the test. AC power to the unit is varied from 85% to 115% nominal and variation in the fundamental emission field strength is recorded. If battery powered, a new, fully charged battery is used. Conducted measurements were made as described in ANSI C63.4 - 2003. The IF bandwidth used for measurement of radiated signal strength was 10 kHz for emission below 30 MHz and 120 kHz for emission from 30 MHz to 1000 MHz. Above 1000 MHz, a resolution bandwidth of 1 MHz is used. Measurements are normally conducted at a measurement distance of three meters. All measurements are extrapolated to three meters using inverse scaling, unless otherwise reported. Measurements taken at a closer distance are so marked. FCC ID: PQN44319RX49 25
