Emission Designator Per CFR 47 §2.201& §2.202, BW = 2M + 2D For FM Mode (Channel Spacing: 12.5 kHz) Emission Designator 11K0F3E In this case, the maximum modulating frequency is 3.0 kHz with a 2.5 kHz deviation. BW = 2(M+D) = 2*(3.0 kHz + 2.5 kHz) = 11 kHz = 11K0 F3E portion of the designator represents an FM voice transmission Therefore, the entire designator for 12.5 kHz channel spacing FM mode is 11K0F3E. For Digital Mode (Channel Spacing: 12.5 kHz) Emission Designator 7K60F1D and 7K60F1E The 99% energy rule (title 47CFR 2.1049) was used for digital mode. It basically states that 99% of the modulation energy falls within X kHz, in this case, 7.60 kHz. The emission mask was obtained from 47CFR 90.210(d). F1D and F1E portion of the designator indicates digital information. Therefore, the entire designator for 12.5 kHz channel spacing digital mode is 7K60F1D and 7K60F1E. Page 16 of 30

Bay Area Compliance Laboratories Corp. (Dongguan) Report No.: RDG190320007-00A FCC §2.1053 §90.210 - RADIATED SPURIOUS EMISSIONS Applicable Standard FCC §2.1053, §90.210 Test Procedure The transmitter was placed on a wooden turntable, and it was transmitting into a non-radiating load, which was also placed on the turntable. The measurement antenna was placed at a distance of 3 meters from the EUT. During the tests, the antenna height and polarization as well as EUT azimuth were varied in order to identify the maximum level of emissions from the EUT .The test was performed by placing the EUT on 3-orthogonal axis. The frequency range up to teeth harmonic of the fundamental frequency was investigated. Remove the EUT and replace it with substitution antenna. A signal generator was connected to the substitution antenna by a non-radiating cable. The absolute levels of the spurious emissions were measured by the substitution. Spurious emissions in dB =10 1g (TXpwr in Watts/0.001)-the absolute level Test Data Environmental Conditions Temperature: 25.8 ℃ Relative Humidity: 54 % ATM Pressure: 100.3 kPa The testing was performed by Vern Shen on 2019-04-19 Test Mode: Transmitting Page 24 of 30

Bay Area Compliance Laboratories Corp. (Dongguan) Report No.: RDG190320007-00A FCC §90.214 - TRANSIENT FREQUENCY BEHAVIOR Applicable Standard Regulations: FCC §90.214 Test method: ANSI/TIA-603-D 2010, section 2.2.19.3 Test Procedure a) Connect the EUT and test equipment as shown on the following block diagram. b) Set the Spectrum Analyzer to measure FM deviation, and tune the RF frequency to the transmitter assigned frequency. c) Set the signal generator to the assigned transmitter frequency and modulate it with a 1 kHz tone at ±12.5 kHz deviation and set its output level to -100dBm. d) Turn on the transmitter. e) Supply sufficient attenuation via the RF attenuator to provide an input level to the Spectrum Analyzer that is 40 dB below the maximum allowed input power when the transmitter is operating at its rated power level. Note this power level on the Spectrum Analyzer as P0. f) Turn off the transmitter. g) Adjust the RF level of the signal generator to provide RF power equal to P0. This signal generator RF level shall be maintained throughout the rest of the measurement. h) Remove the attenuation 1, so the input power to the Spectrum Analyzer is increased by 30 dB when the transmitter is turned on. i) Adjust the vertical amplitude control of the spectrum analyzer to display the 1000 Hz at ±4 divisions vertically centered on the display. Set trigger mode of the Spectrum Analyzer to “Video”, and tune the “trigger level” on suitable level. Then set the “tiger offset” to -10ms for turn on and -15ms for turn off. j) Turn on the transmitter and the transient wave will be captured on the screen of Spectrum Analyzer. Observe the stored display. The instant when the 1 kHz test signal is completely suppressed is considered to be ton. The trace should be maintained within the allowed divisions during the period t1 and t2. k) Then turn off the transmitter, and another transient wave will be captured on the screen of Spectrum Analyzer. The trace should be maintained within the allowed divisions during the period t3. EUT Attenuator 1 Attenuator 2 Combiner Spectrum Analyzer Spectrum Analyzer Signal Generator Page 28 of 30
