        This is an application for certification of a transmitter for the Toy RC Monster
        Spinning Car, and there has a receiver which associated with this EUT has
        been subjected to the FCC SDOC.

1.3     Test Methodology

        Radiated emission measurements were performed according to the
        procedures in ANSI C63.10 (2013). Radiated Emission measurement was
        performed in a Semi-anechoic chamber. Preliminary scans were performed
        in the Semi-anechoic chamber 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.

  Test Report
                                                       Intertek Report No.: SZHH01361694-001

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 C63.10 (2013).

        The EUT was powered by one new 9V 6F22 battery during test.

        For maximizing emissions below 30 MHz, the EUT was rotated through 360°,
        the centre of the loop antenna was placed 1 meter above the ground, and the
        antenna polarization was changed. For maximizing emission at and above 30
        MHz, 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
        report in Exhibit 3.0.

        The unit was operated standalone and placed in the centre 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 mounted to a plastic stand if
        necessary and placed on the polystyrene turntable, which enabled the Senior
        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. Once the unit is powered
        up, it can transmit the RF signal continuously.

2.3     Special Accessories

        There are no special accessories necessary for compliance of this product.

2.4     Equipment Modification

        Any modifications installed previous to testing by Jinxi County Jingang
        Industrial Co., Ltd will be incorporated in each production model sold/leased in
        the United States.

        No modifications were installed by Intertek Testing Services Shenzhen Ltd.
        Longhua Branch.

2.5     Measurement Uncertainty

        When determining of the test conclusion, the Measurement Uncertainty of test
        has been considered.

2.6     Support Equipment List and Description
        N/A.

  Test Report
                                                          Intertek Report No.: SZHH01361694-001

3.0     Emission Results

        Data is included of the 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.


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), Average Factor (optional) from the
        measured reading. The basic equation with a sample calculation is as follows:
        FS = RA + AF + CF - AG - AV
        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
                       AV = Average Factor 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 - AV 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 and
        average factor of 5 dB are subtracted, giving a field strength of 27 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 = 18.0 dBµV
        CF = 1.6 dB                           LF = 9.0 dB
        AG = 29.0 dB
        AV = 5.0 dB
        FS = RR + LF
        FS = 18 + 9 = 27 dBµV/m

        Level in µV/m = Common Antilogarithm [(27 dBµV/m)/20] = 22.4 µV/m

  Test Report
                                                       Intertek Report No.: SZHH01361694-001

8.1     Measured Bandwidth

        The plot saved in bw.pdf which shows the fundamental emission is confined in
        the specified band. And it also shows that the emission is at least 44.13dB
        below the carrier level at the band edge (49.81MHz and 49.91 MHz). It meets
        the requirement of Section 15.235(b).

        Pursuant to FCC part 15 Section 15.215(c), the 20dB bandwidth of the emission
        was contained within the frequency band designated (mentioned as above)
        which the EUT operated. The effects, if any, from frequency sweeping,
        frequency hopping, other modulation techniques and frequency stability over
        excepted variations in temperature and supply voltage were considered.

        The test plots are attached as below

8.2     Discussion of Pulse Desensitization

        The determination of pulse desensitivity was made in accordance with Hewlett
        Packard Application Note 150-2, Spectrum Analysis ... Pulsed RF.

        The effective period (Teff) was approximately 507.2µs and 1449.3µs for a digital
        "1" bit, as shown in the plots of Exhibit 8.3. With a resolution bandwidth (3 dB)
        of 100 kHz, the pulse desensitivity factor was 0 dB.


8.3     Calculation of Average Factor

        Averaging factor in dB = 20 log (duty cycle)

        The specification for output field strengths in accordance with the FCC rules
        specify measurements with an average detector. During testing, a spectrum
        analyzer incorporating a peak detector was used. Therefore, a reduction factor
        can be applied to the resultant peak signal level and compared to the limit for
        measurement instrumentation incorporating an average detector.

        The time period over which the duty cycle is measured is 100 milliseconds, or
        the repetition cycle, whichever is a shorter time frame. The worst case (highest
        percentage on) duty cycle is used for the calculation. The duty cycle is
        measured by placing the spectrum analyzer in zero scan (receiver mode) and
        linear mode at maximum bandwidth (3 MHz at 3 dB down) and viewing the
        resulting time domain signal output from the analyzer on a Tektronix
        oscilloscope. The oscilloscope is used because of its superior time base and
        triggering facilities.

        A plot of the worst-case duty cycle as detected in this manner are saved with
        filename: af.pdf

        The duty cycle is simply the on-time divided by the period:

         The duration of one cycle = 18.1884ms
         Effective period of the cycle = 1449.3us x 4 + 507.2μs x 10 =10869.20μs
         DC =10.8692ms / 18.1884ms =0.5976 or 59.76%

         Therefore, the averaging factor is found by 20 log10 (0.5976) =-4.5dB

        The test plots are attached as below

8.4     Emissions Test Procedures

        The following is a description of the test procedure used by Intertek Testing
        Services in the measurements of transmitters operating under Part 15, Subpart
        C rules.

        The test set-up and procedures described below are designed to meet the
        requirements of ANSI C63.10 - 2013.

        The transmitting equipment under test (EUT) is placed on a polystyrene
        turntable which is four feet in diameter and approximately 0.8 meter in height
        above the ground plane. 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 EUT is adjusted through all
        three orthogonal axes to obtain maximum emission levels. The antenna height
        and polarization are varied during the testing to search for maximum signal
        levels.

        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. A detailed description for the calculation of the average factor can
        be found in Exhibit 8.3.

        The frequency range scanned is from the lowest radio frequency signal
        generated in the device which is greater than 9 kHz to the tenth harmonic of the
        highest fundamental frequency or 40 GHz, whichever is lower.

  Test Report
                                                              Intertek Report No.: SZHH01361694-001

8.4     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 are made as described in ANSI C63.10 - 2013.

        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. Where pulsed transmissions of short enough pulse duration warrant, a
        greater bandwidth is selected according to the recommendations of Hewlett
        Packard Application Note 150-2. A discussion of whether pulse desensitivity is
        applicable to this unit is included in this report (See Exhibit 8.2).

        Transmitter measurements are normally conducted at a measurement distance
        of three meters. However, to assure low enough noise floor in the restricted
        bands, signals are acquired at a distance of one meter or less. All
        measurements are extrapolated to three meters using inverse scaling, but those
        measurements taken at a closer distance are so marked.
