The EUT can be powered by DC 14.4V, 2500mAh rechargeable battery and/or DC 20V with recharging base and/or DC 20V with Adapter. The EUT can’t transmit while charged by adapter directly. For more detail information pls. refer to the user manual. Antenna Type: PCB antenna Modulation Type: GFSK Antenna Gain: 2dBi For electronic filing, the brief circuit description is saved with filename: descri.pdf. 2.2 Related Submittal(s) Grants This is an application for certification of a transmitter for the Robotic Vacuum which has 2.4G RF transmitter function, and related report for FCC SDOC is subjected to report number: 190523033SZN-001. The part of a system that operated with this devise is under the FCC ID:2ATRE-QQ6-Base. The Robotic Vacuum contains a WIFI module which has been granted under the FCC ID:2AHMRESP12S. 2.3 Test Methodology Both AC mains line-conducted and radiated emission measurements were performed according to the procedures in ANSI C63.10 (2013). Radiated emission measurement was performed in Semi-anechoic chamber and conducted emission measurement was performed in shield room. For radiated emission measurement, preliminary scans were performed in the semi-anechoic chamber only to determine the 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. All other measurements were made in accordance with the procedures in part 2 of CFR 47. 2.4 Test Facility The Semi-Anechoic chamber and shield room used to collect the radiated data and conducted data are Intertek Testing Services Shenzhen Ltd. Longhua Branch and located at 101, 201, Building B, No. 308 Wuhe Avenue, Zhangkengjing Community, GuanHu Subdistrict, LongHua District, ShenZhen, P.R. China. This test facility and site measurement data have been fully placed on file with the FCC (Registration Number: CN1188). Version: 01-November-2017 Page: 5 of 28 FCC ID 249_C

Test Report Intertek Report No.: 190523032SZN-001 3.0 System Test Configuration 3.1 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 DC 14.4V, 2500mAh rechargeable battery or DC 20V with recharging base during the test. Both standalone and charged with recharging base have been considered. The EUT contains a WIFI module which was installed and operating during the test, only the worst data was reported in this report. 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 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 Section 4. 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 placed on a turntable, which enabled the engineer to maximize emissions through its placement in the three orthogonal axes. 3.2 EUT Exercising Software There was no special software to exercise the device. 3.3 Special Accessories No special accessories used. 3.4 Equipment Modification Any modifications installed previous to testing by MARIGOLD ENTERPRISES 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. Version: 01-November-2017 Page: 6 of 28 FCC ID 249_C

Test Report Intertek Report No.: 190523032SZN-001 4.0 Emission Results Data is included worst-case configuration (the configuration which resulted in the highest emission levels). 4.1 Radiated Test Results A sample calculation, configuration photographs and data tables of the emissions are included. 4.1.1 Field Strength Calculation The field strength is calculated by adding the reading on the Spectrum Analyzer to the factors associated with preamplifiers (if any), antennas, cables, pulse desensitization and average factors (when specified limit is in average and measurements are made with peak detectors). A sample calculation is included below. FS = RA + AF + CF - AG + PD + 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 PD = Pulse Desensitization in dB AV = Average Factor in -dB In the radiated emission table which follows, the reading shown on the data table may reflect the preamplifier gain. An example of the calculations, where the reading does not reflect the preamplifier gain, follows: FS = RA + AF + CF - AG + PD + AV Assume a receiver reading of 62.0 dBµV is obtained. The antenna factor of 7.4 dB and cable factor of 1.6 dB is added. The amplifier gain of 29 dB is subtracted. The pulse desensitization factor of the spectrum analyzer was 0 dB, and the resultant average factor was -10 dB. The net field strength for comparison to the appropriate emission limit is 32 dBµV/m. This value in dBµV/m was converted to its corresponding level in µV/m. RA = 62.0 dBµV AF = 7.4 dB CF = 1.6 dB AG = 29.0 dB PD = 0 dB AV = -10 dB FS = 62 + 7.4 + 1.6 - 29 + 0 = 42 dBµV/m Level in µV/m = Common Antilogarithm [(42 dBµV/m)/20] = 125.9 µV/m Version: 01-November-2017 Page: 8 of 28 FCC ID 249_C

Test Report Intertek Report No.: 190523032SZN-001 9.0 Miscellaneous Information This miscellaneous information includes details of the measured bandedge, 20dB Bandwidth, the test procedure and calculation of factor such as pulse desensitization. 9.1 Bandedge Plot The test plots are attached as below. From the plot, the field strength of any emissions outside of the specified frequency band are attenuated to the general radiated emission limits in section 15.209. It fulfils the requirement of 15.249(d). Peak Measurement Bandedge compliance is determined by applying marker-delta method, i.e (Bandedge Plot). (i) Lower channel 2402.000 MHz: Peak Resultant field strength = Fundamental emissions (peak value) – delta from the bandedge plot = 92.4 dBµv/m-27.3 dB = 65.1 dBµv/m Average Resultant field strength = Fundamental emissions (average value) – delta from the bandedge plot = 41.6 dBµv/m-27.3 dB = 14.3 dBµv/m (ii) Upper channel 2480.000 MHz: Peak Resultant field strength = Fundamental emissions (peak value) – delta from the bandedge plot = 91.9 dBµv/m-35.0 dB = 56.9 dBµv/m Average Resultant field strength = Fundamental emissions (average value) – delta from the bandedge plot = 41.1 dBµv/m-35.0 dB = 6.1 dBµv/m The resultant field strength meets the general radiated emission limit in section 15.209, which does not exceed 74dBµv/m (Peak Limit) and 54dBµv/m (Average Limit).

Test Report Intertek Report No.: 190523032SZN-001 9.2 20dB Bandwidth 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 reported as below. Version: 01-November-2017 Page: 22 of 28 FCC ID 249_C

Test Report Intertek Report No.: 190523032SZN-001 9.3 Discussion of Pulse Desensitization Pulse desensitivity is not applicable for this device. The effective period (Teff) is approximately 0.1159ms for a digital "1" bit, as shown in the plots of Section 9.4. With a resolution bandwidth (3 dB) of 100 kHz, the pulse desensitivity factor was 0 dB 9.4 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. The duty cycle is simply the on-time divided by the period: The duration of one cycle = 40.0725ms Effective period of the cycle = 0.1159ms = DC =0.1159ms / 40.0725ms =0.0029 or 0.29% Therefore, the averaging factor is found by 20 log10 ( 0.0029 ) = -50.8dB The test plots are attached as below.

Test Report Intertek Report No.: 190523032SZN-001 9.5 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 table which is four feet in diameter and approximately 12mm up to 1GHz and 1.5 meter above 1GHz 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 Section 9.4. 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. Detector function for conducted emissions is in QP & AV mode and IFBW setting is 9 kHz from the frequency band 150 kHz to 30MHz. Version: 01-November-2017 Page: 26 of 28 FCC ID 249_C

Test Report Intertek Report No.: 190523032SZN-001 9.5 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 Section 9.3). Above 1000 MHz, a resolution bandwidth of 1 MHz is used, RBW 3MHz used for fundamental emission. Transmitter measurements are normally conducted at a measurement distance of three meters. However, to assure low enough noise floor in the restricted 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, but those measurements taken at a closer distance are so marked. Version: 01-November-2017 Page: 27 of 28 FCC ID 249_C
