Report No: 140414100GZU-001 Issued: 16 June 2014 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 sends 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-3040C6. 1.3 Test Methodology Radiated emission measurements were performed according to the procedures in ANSI C63.10:2009 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 All of the tests are performed at: Intertek Testing Services Shenzhen Ltd. Guangzhou Branch. Block E, No.7-2 Guang Dong Software Science Park, Caipin Road, Guangzhou Science City, GETDD Guangzhou, China 510663. This test facility and site measurement data have been fully placed on file with the FCC, test firm registration number is 549654. FCC ID: YHXESQ-3040R6 Page 3 of 19

Report No: 140414100GZU-001 Issued: 16 June 2014 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 C63.10:2009 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 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 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-3040R6 Page 5 of 19

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-3040R6 Page 7 of 19

Report No: 140414100GZU-001 Issued: 16 June 2014 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 → FS = RA + Correct Factor Where FS = Peak 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 Correct Factor = AF + CF – AG + PD Unless otherwise specified, e.g. § 15.255(b), when the radiated emission limits are expressed in terms of the average value of the emission, and pulsed operation is employed, the average value of field strength shall be determined by: Average value = Peak value + Average factor FCC ID: YHXESQ-3040R6 Page 8 of 19

Report No: 140414100GZU-001 Issued: 16 June 2014 3.4 Bandedges Measurement 3.4.1 Limited of the bandedges measurement Sec15.249: (d) Emissions radiated outside of the specified frequency bands, except for harmonics, shall be attenuated by at least 50 dB below the level of the fundamental or to the general radiated emission limits in Section 15.209, whichever is the lesser attenuation. (e) As shown in Section 15.35(b), for frequencies above 1000 MHz, the above field strength limits in paragraphs (a) and (b) of this section are based on average limits. However, the peak field strength of any emission shall not exceed the maximum permitted average limits specified above by more than 20 dB under any condition of modulation. For point-to-point operation under paragraph (b) of this section, the peak field strength shall not exceed 2500 millivolts/meter at 3 meters along the antenna azimuth. Sec15.215: (c) Intentional radiators operating under the alternative provisions to the general emission limites, as contained in §§15.217 through 15.257 and in Subpart E of this part, must be designed to ensure that the 20dB bandwidth may otherwise be specified in the specific rule section under which the equipment operates, is contained within the frequency band designated in the rule section under which the equipment is operated. 3.4.2 Test Setup Refer to 1.4 FCC ID: YHXESQ-3040R6 Page 12 of 19

Report No: 140414100GZU-001 Issued: 16 June 2014 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 = 93.8dBµv/m – 36.7dB = 57.1dBµv/m Average Resultant field strength = Fundamental emissions (AV value) – delta from the bandedge plot = 79.8dBµv/m – 36.7dB = 43.1dBµv/m (ii) Upper bandedge: Peak Resultant field strength = Fundamental emissions (peak value) – delta from the bandedge plot = 93.8dBµv/m – 40.0dB = 53.8dBµv/m Average Resultant field strength = Fundamental emissions (AV value) – delta from the bandedge plot = 79.8dBµv/m – 40.0dB = 39.8dBµv/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: 140414100GZU-001 Issued: 16 June 2014 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. FCC ID: YHXESQ-3040R6 Page 17 of 19

Report No: 140414100GZU-001 Issued: 16 June 2014 The duty cycle is simply the on-time divided by the period: The duration of one cycle = 6.522ms Effective period of the cycle = 1.304ms DC =1.304/6.522=0.1999 or 19.99% Therefore, the averaging factor is found by 20lg0.1999=-14dB FCC ID: YHXESQ-3040R6 Page 18 of 19
