Report No: GZ11100388-2 1. General Description 1.1 Product Description The equipment under test (EUT) is a transceiver for remote control of Black Electric Smoker at 2.440GHz. The EUT is powered by 2*1.5V/AAA battery. It send the command of temperature & time settings & lighting to the Electric Smoker, and it sends a signal to Electric Smoker to request “meat probe” temperature and receives temperature information (probe) from Electric Smoker. Antenna Type: internal integrated antenna. The remote controllers of the model: 20070312, 20072112, 20072212, 20072312, 20072412, 20072912 20070512, 20072512, 20072612, 20072712, 20072812, 20073012 are the same as the test model 20070312 in hardware and software aspect. The only differences are the appearance, and model number for trading purpose. We tested the remote controllers, 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 when tested as received. 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-3040C3. 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. 1.4 Test Facility The Radiated Emission test is performed at: Compliance Certification Services (Shenzhen) Inc. located at No.10-1Mingkeda Logistics Park, No.18Huanguan South RD. Guanlan Town, Baoan District Shenzhen China. This test facility and site measurement data have been fully placed on file with the FCC, test firm registration number is 441872.

Report No: GZ11100388-2 2. 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 C63.4 (2003). The EUT was powered by 2*1.5V/AAA battery in the testing. Type of modulation: GFSK modulation, and only the worst data was reported in this report. The unit was operated standalone and placed in the center of the turntable. For maximizing emissions, the unit was placed in the center of the turntable, and the turntable was rotated through 360°, the antenna hei ght 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 Chapter 3. 2.2 EUT Exercising Software There was no special software to exercise the device. 2.3 Special Accessories No special accessories used. 2.4 Equipment Modification Any modifications installed previous to testing by Masterbuilt Manufacturing Inc will be incorporated in each production model sold/leased in the United States. No modifications were installed by Intertek Testing Services Shenzhen Ltd. Guangzhou Branch. 2.5 Support Equipment List and Description N/A FCC ID: YHXESQ-3040R3 Page 5 of 16

Report No: GZ11100388-2 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-3040R3 Page 7 of 16

m Report No: GZ1 1 100388—2 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 dBuV/m RA = Receiver Amplitude (including preamplifier) in dBuV 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 preampilifier gain, follows: FS = RA + AF + CF — AG + PD + AV Assume a receiver reading of 62.0 dBuV 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 dBuiV/m. This value in dBuV/m was converted to its corresponding level in uV/m. RA = 62.0 dBuV AF = 74 dB CF = 1.60B 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 dBuV/m Level in V/m = Common Antilogarithm [(32 dBuV/m)/20] = 39.8 uiV/im FCC ID: YHXESQ—3040R3 Page 8 of 16

Report No: GZ11100388-2 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 fulfils 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 = 83.1dBµv/m – 42.2dB = 40.9dBµv/m Average Resultant field strength = Fundamental emissions (peak value) – delta from the bandedge plot = 70.7dBµv/m – 42.2dB = 28.5dBµv/m (ii) Upper bandedge: Peak Resultant field strength = Fundamental emissions (peak value) – delta from the bandedge plot = 83.1dBµv/m – 48.4dB = 34.7dBµv/m Average Resultant field strength = Fundamental emissions (peak value) – delta from the bandedge plot = 70.7dBµv/m – 48.4dB = 22.3dBµv/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: GZ11100388-2 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 = 3.967ms Effective period of the cycle = 0.95ms DC =0.95/3.967=0.2395 or 23.95% Therefore, the averaging factor is found by 20lg0.2395=-12.4dB FCC ID: YHXESQ-3040R3 Page 15 of 16
