Better Sourcing Worldwide Ltd. Intertek Report No: 19031421HKG‐001 TEST REPORT 1.0 GENERAL DESCRIPTION 1.1 Product Description The Equipment Under Test (EUT) is portable controller for Remote controlled car set which operates at 27.145MHz. The EUT is powered by 2 x 1.5V AAA batteries. After switch on the EUT, the car will be moved forward or backward, turned left or right based on the joystick control in the controller. Antenna Type: Internal, Integral For electronic filing, 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 transmitter. 1.3 Test Methodology Radiated emission measurements were performed according to the procedures in ANSI C63.10 (2013). All radiated measurements were performed in an 3m Chamber. Preliminary scans were performed in the 3m 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. 1.4 Test Facility The 3m Chamber facility used to collect the radiated data is located at Workshop No. 3, G/F., World‐Wide Industrial Centre, 43‐47 Shan Mei Street, Fo Tan, Sha Tin, N.T., Hong Kong. This test facility and site measurement data have been placed on file with the FCC. Page 5 of 15

Better Sourcing Worldwide Ltd. Intertek Report No: 19031421HKG‐001 TEST REPORT 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 device was powered by new DC 3.0V (2 x 1.5V AAA batteries). 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 rear of unit shall be flushed with the rear of the table. 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 wooden 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. Once the unit is powered up, it transmits the RF signal continuously. 2.3 Special Accessories There are no special accessories necessary for compliance of this product. 2.4 Measurement Uncertainty When determining of the test conclusion, the Measurement Uncertainty of test has been considered. Uncertainty and Compliance ‐ Unless the standard specifically states that measured values are to be extended by the measurement uncertainty in determining compliance, all compliance determinations are based on the actual measured value. 2.5 Support Equipment List and Description N/A.

Better Sourcing Worldwide Ltd. Intertek Report No: 19031421HKG‐001 TEST REPORT 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 Page 7 of 15

Better Sourcing Worldwide Ltd. Intertek Report No: 19031421HKG‐001 TEST REPORT 8.0 MISCELLANEOUS INFORMATION The miscellaneous information includes details of the test procedure and measured bandwidth / calculation of factor such as pulse desensitization and averaging factor (calculation and timing diagram). 8.1 Measured Bandwidth The plot shows the fundamental emission is confined in the specified band. And it also shows that the emission is at least 33.7 dB below the carrier level at the band edge (26.96 and 27.28 MHz). It meets the requirement of Section 15.227(b). Pursuant to FCC Part 15 Section 15.215(c), the 20dB bandwidth of the emission was contained within the frequency band designed (mentioned as above) which the EUT operated. The effects, if any, from frequency sweeping, frequency hopping, other modulation techniques and frequency stability over expected variations in temperature and supply voltage were considered.

Better Sourcing Worldwide Ltd. Intertek Report No: 19031421HKG‐001 TEST REPORT 8.2 Discussion of Pulse Desensitization Pulse desensitivity is not applicable for this device. Since the transmitter transmits the RF signal continuously. 8.3 Calculation of Average Factor It is not necessary to apply average factor as the measured (peak) data has been complied with average limit of the radiated emission. 8.4 Emissions Test Procedures The following is a description of the test procedure used by Intertek Testing Services Hong Kong Ltd. in the measurements of transmitter operating under the Part 15, Subpart C rules. The transmitting equipment under test (EUT) is placed on a wooden turntable which is four feet in diameter and approximately 0.8m in height above the ground plane for emission measurement at or below 1GHz and 1.5m in height above the ground plane for emission measurement above 1GHz. 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 axis to obtain maximum emission levels. 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. 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.

Better Sourcing Worldwide Ltd. Intertek Report No: 19031421HKG‐001 TEST REPORT 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 were made as described in ANSI C63.10 (2013). The IF bandwidth used for measurement of radiated signal strength was 100 kHz or greater when frequency is below 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 8.1). Above 1000 MHz, a resolution bandwidth of 3 MHz is used. Transmitter measurements are normally conducted at a measurement distance of three meters. However, to assure low enough noise floor in the forbidden bands and above 1 GHz, signals are acquired at a distance of one meter or less. All measurements are extrapolated to three meters using inverse scaling, unless otherwise reported. Measurements taken at a closer distance are so marked. Page 13 of 15
