Bay Area Compliance Laboratories Corp. (Shenzhen) Report No.: RSZ190505001-00C FCC §1.1307 (b) (1) &§2.1093 – RF EXPOSURE Applicable Standard According to FCC §2.1093 and §1.1307(b) (1), systems operating under the provisions of this section shall be operated in a manner that ensure that the public is not exposed to radio frequency energy level in excess of the Commission’s guideline. According to KDB 447498 D01 General RF Exposure Guidance The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤ 50 mm are determined by: [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] · [√f(GHz)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR, where 1. f(GHz) is the RF channel transmit frequency in GHz. 2. Power and distance are rounded to the nearest mW and mm before calculation. 3. The result is rounded to one decimal place for comparison. 4. When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test Exclusion. For worst case: Maximum Tune-up Calculated Frequency power Calculated Threshold SAR Test Distance (MHz) Value (1-g SAR) Exclusion (dBm) (mW) (mm) 467.6375 20 100 40 1.7 3.0 Yes When standalone SAR exclusion applies to an antenna that transmits simultaneously with other antennas, the standalone SAR value must be estimated according to the following to determine the simultaneous transmission SAR test exclusion criteria: [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] · [√f(GHz)/x] W/kg, for test separation distances ≤ 50 mm; where x=7.5 for 1-g SAR So, the calculated value for FRS is 0.23 W/kg Refer to the DSS and DTS report, the highest Calculated Value for 2.4G band is 0.13 W/kg The sum of 2.4G&FRS transmits simultaneously calculated value is 0.23W/kg+0.13W/kg=0.36W/kg, less than the limit 1.6W/kg Result: Compliance FCC Part 95 Page 9 of 30

Bay Area Compliance Laboratories Corp. (Shenzhen) Report No.: RSZ190505001-00C FCC §95.587(b)(1) – ANTENNA REQUIREMENT Applicable Standard According to FCC § 95.587, (b) Antenna. The antenna of each FRS transmitter type must meet the following requirements. (1) The antenna must be a non-removable integral part of the FRS transmitter type. Antenna Connector Construction The EUT has an integral antenna arrangement, fulfill the requirement of this section. Please refer to the EUT photos. Result: Compliance. FCC Part 95 Page 11 of 30

Bay Area Compliance Laboratories Corp. (Shenzhen) Report No.: RSZ190505001-00C FCC §2.1046 & §95.567 - RF OUTPUT POWER Applicable Standard Per FCC §2.1046, and §95.567, Each FRS transmitter type must be designed such that the effective radiated power (ERP) on channels 8 through 14 does not exceed 0.5 Watts and the ERP on channels 1 through 7 and 15 through 22 does not exceed 2.0 Watts. 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. 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 emissions were measured by the substitution. Test Data Environmental Conditions Temperature: 24 °C Relative Humidity: 50 % ATM Pressure: 101.0 kPa The testing was performed by Andy Yu on 2019-05-30. Test Mode: Transmitting Indicated Test Ant.

Bay Area Compliance Laboratories Corp. (Shenzhen) Report No.: RSZ190505001-00C FCC §2.1053 & §95.579- RADIATED SPURIOUS EMISSION Applicable Standard FCC §2.1053 and §95.579. Each FRS transmitter type must be designed to satisfy the applicable unwanted emissions limits in this paragraph. (a) Attenuation requirements. The power of unwanted emissions must be attenuated below the carrier power output in Watts (P) by at least: (1) 25 dB (decibels) in the frequency band 6.25 kHz to 12.5 kHz removed from the channel center frequency. (2) 35 dB in the frequency band 12.5 kHz to 31.25 kHz removed from the channel center frequency. (3) 43 + 10 log (P) dB in any frequency band removed from the channel center frequency by more than 31.25 kHz. (b) Measurement bandwidths. The power of unwanted emissions in the frequency bands specified in paragraphs (a)(1) and (2) of this section is measured with a reference bandwidth of 300 Hz. The power of unwanted emissions in the frequency range specified in paragraph (a)(3) is measured with a reference bandwidth of at least 30 kHz. (c) Measurement conditions. The requirements in this section apply to each FRS transmitter type both with and without the connection of permitted attachments, such as an external speaker, microphone and/or power cord. Test Procedure The transmitter was placed on a wooden 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 tenth 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 Spurious attenuation limit in dB = 43+10 Log10 (power out in Watts) Test Data Environmental Conditions Temperature: 25 °C Relative Humidity: 52 % ATM Pressure: 101.0 kPa The testing was performed by Leo Huang on 2019-05-23.

Bay Area Compliance Laboratories Corp. (Shenzhen) Report No.: RSZ190505001-00C FCC§2.1055 (d) & §95.565 - FREQUENCY STABILITY Applicable Standard According to FCC §2.1055(a) (1), the frequency stability shall be measured with variation of ambient temperature from –30 ºC to +50 ºC, and according to FCC 2.1055(d) (2), the frequency stability shall be measured with reducing primary supply voltage to the battery operating end point which is specified by the manufacturer. According to FCC §95.565, Each FRS transmitter type must be designed such that the carrier frequencies remain within ±2.5 parts-per-million of the channel center frequencies specified in §95.563 during normal operating conditions. Test Procedure Frequency Stability vs. Temperature: The equipment under test was connected to an external DC power supply and the RF output was connected to a Frequency Counter via feed-through attenuators. The EUT was placed inside the temperature chamber. The DC leads and RF output cable exited the chamber through an opening made for the purpose. After the temperature stabilized for approximately 20 minutes, the frequency output was recorded from the Frequency Counter. Frequency Stability vs. Voltage (item 1or item 2 will be chosen according to different condition) : 1) Vary primary supply voltage from 85 to 115 percent of the nominal value for other than hand carried battery equipment. 2) For hand carried, battery powered equipment, reduce primary supply voltage to the battery operating end point which shall be specified by the manufacturer. The output frequency was recorded for each voltage.
