Circus World Displays Limited Intertek Report No: 18071570HKG-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 120VAC. 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 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 The EUT exercise program (if any) used during radiated testing was designed to exercise the various system components in a manner similar to a typical use. 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. 2.5 Support Equipment List and Description 1. 1 X USB cable with length of 0.5 meter long with 2.38-ohm resistive load (2.1A load) 2. 1 X Audio cable with length of 1.2 meter long with termination (Provided by Union Trust) 3.

Circus World Displays Limited Intertek Report No: 18071570HKG-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 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 = 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 27

Circus World Displays Limited Intertek Report No: 18071570HKG-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 Radiated Emission on the Bandedge From the following plots, they show that the fundamental emissions are confined in the specified band (2400MHz to 2483.5MHz). In case of the fundamental emissions are within two standard bandwidths from the bandedge, the delta measurement technique is used for determining bandedge compliance. Standard bandwidth is the bandwidth specified by ANSI C63.10 (2013) for frequency being measured. Emissions radiated outside of the specified frequency bands, except harmonics, are attenuated by 50dB below the level of the fundamental or to the general radiated emissions limits in Section 15.209 / RSS-210 4.4, whichever is the lesser attenuation, which meet the requirement of part 15.249(d) / RSS-210 B.10.

Circus World Displays Limited Intertek Report No: 18071570HKG-001 TEST REPORT 8.2 Discussion of Pulse Desensitization Pulse desensitivity is not applicable for this device. The effective period (Teff) is approximately 625µs for a digital “1” bit which illustrated on technical specification, with a resolution bandwidth (3dB) of 3MHz, so the pulse desensitivity factor is 0dB. 8.3 Calculation of Average Factor N/A Page 20 of 27

Circus World Displays Limited Intertek Report No: 18071570HKG-001 TEST REPORT 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. For line conducted emissions, the range scanned is 150 kHz to 30 MHz. Page 21 of 27

Circus World Displays Limited Intertek Report No: 18071570HKG-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 22 of 27

Circus World Displays Limited Intertek Report No: 18071570HKG-001 TEST REPORT 8.4.2 Conducted Emission Test Procedures For tabletop equipment, the EUT along with its peripherals were placed on a 1.0m(W)×1.5m(L) and 0.8m in height wooden table. For floor-standing equipment, the EUT and all cables were insulated, if required, from the ground plane by up to 12 mm of insulating material. The EUT was adjusted to maintain a 0.4 meter space from a vertical reference plane. The EUT was connected to power mains through a line impedance stabilization network (LISN), which provided 50 ohm coupling impedance for measuring instrument and the chassis ground was bounded to the horizontal ground plane of shielded room. The excess power cable between the EUT and the LISN was bundled. All connecting cables of EUT and peripherals were moved to find the maximum emission. 8.4.3 Conducted Emission Test Setup AC Power LISN 1 EUT Peripherals LISN 2 EMI Receiver AC Power Page 24 of 27
