Report No: GZ11100388-3 1. General Description 1.1 Product Description The Equipment Under Test (EUT) is a transceiver for Black Electric Smoker with RF at 2.440GHz. It is powered by AC mains:120V/60Hz. During normal use, it send temperature information (probe) to remote control, when the “meat probe” button on remote control is pressed and receive control command (temp.and time) from remote control. Antenna Type: internal integrated antenna. The model: 20070312, 20072112, 20072212, 20072312, 20072412, 20072912, 20070512, 20072512, 20072612, 20072712, 20072812, 20073012 are the same in hardware and software aspect. The only differences are the appearance, and model no.for trading purpose. The power of 20070512, 20072512, 20072612, 20072712, 20072812, 20073012 is 1200W. The power of 20070312, 20072112, 20072212, 20072312, 20072412, 20072912 is 800W We tested the black Electric Smoker, model:20070312, to determine if it was in compliance with the relevant FCC standards. We found that the unit met the requirements of FCC part 15.249. The worst case’s test data was presented in this test report. 1.2 Related Submittal (s) / Grants The FCC ID of corresponding transceiver for this transceiver is YHXESQ-3040R3. 1.3 Test Methodology Radiated emission measurements were performed according to the procedures in ANSI C63.4 :2003. Radiated emission measurement was performed in semi-anechoic chamber 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. Conducted emission test was performed according to ANSI C63.4: 2003. The EUT was set to achieve the maximum emission level. The mains terminal disturbance voltage was measured with the EUT in a shielded room. The EUT was connected to AC power source through an Artificial Mains Network which provides a 50 linear impedance Artificial hand is used if appropriate (for handheld apparatus). The load/control terminal disturbance voltage was measured with passive voltage probe if appropriate. The vertical conducting plane or wall of a screened room shall be located 40 cm to the rear of the EUT. All other surfaces of tabletop EUTs shall be at least 80 cm from any other grounded conducting surface, including the case or cases of one or more LISNs The table-top EUT was placed on a 0.8m high non-metallic table above earthed ground plane(Ground Reference Plane).And for floor standing EUT, was placed on a 0.1m high non-metallic supported on GRP. The Artificial Mains Network is situated at a distance of 0.8m from the EUT. During the test, mains lead of EUT excess 0.8m was folded back and forth parallel to the lead so as to form a horizontal bundle with a length between 0.3m and 0.4m. The bandwidth of test receiver was set at 9 kHz. The frequency range from 150 kHz to 30MHz was checked. FCC ID: YHXESQ-3040C3 Page 3 of 18

Report No: GZ11100388-3 3.3 Radiated Emission 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. 3.3.1 Radiated Emission Limits According to FCC 15.249, operating within the bands 2400-2483.5 MHz, the field strength of emissions from intentional radiators operated within this frequency bands shall comply with the following: Fundamental Field Strength Field Strength Frequency of Fundamental of Harmonics (MHz) (millivolts/meter) (microvolts/meter) 2400 - 2483.5 50 500 3.3.2 Test Setup Reference 1.4 FCC ID: YHXESQ-3040C3 Page 9 of 18

Report No: GZ11100388-3 3.3.3 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 → FS = RA + Correct Factor + 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 Correct Factor = AF + CF – AG + PD 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 Correct Factor = 7.4 + 1.6 – 29.0 + 0 = -20 dB FS = 62 + (-20) + (-10) = 32 dBµV/m Level in µV/m = Common Antilogarithm [(32 dBµV/m)/20] = 39.8 µV/m FCC ID: YHXESQ-3040C3 Page 10 of 18

Report No: GZ11100388-3 3.4.4 Test Result 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 fulfil the requirement of 15.249(d). Peak Measurement Bandedge compliance is determined by applying marker-delta method, i.e ( Bandedge Plot). (i) Lower bandedge: Peak Resultant field strength = Fundamental emissions (peak value) – delta from the bandedge plot = 88.0dBµv/m – 48.6dB = 39.4dBµv/m Average Resultant field strength = Fundamental emissions (peak value) – delta from the bandedge plot = 69.3dBµv/m – 48.6dB = 20.7dBµv/m (ii) Upper bandedge: Peak Resultant field strength = Fundamental emissions (peak value) – delta from the bandedge plot = 88.0dBµv/m – 48.0dB = 40.0dBµv/m Average Resultant field strength = Fundamental emissions (peak value) – delta from the bandedge plot = 69.3dBµv/m – 48.0dB = 21.3dBµv/m The resultant field strength meets the general radiated emission limit in section 15.209, which does not exceed 74 dBµv/m (Peak Limit) and 54dBµv/m (Average Limit).

Report No: GZ11100388-3 3.4.5 Transmitter Duty Cycle Calculation FCC Rule 15.35(b, c) 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 (1 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 is shown below. The duty cycle is simply the on-time divided by the period: The duration of one cycle = 13.29ms Effective period of the cycle = 1.542ms DC =1.542/13.29=0.1160 or 11.60% Thererfor, the averaging factor is found by 20lg0.1160=-18.7dB FCC ID: YHXESQ-3040C3 Page 17 of 18
