(Suzhou) Co., Ltd. 1 General Information Report No.: SEWM2311000466RG10 Rev.: 01 Page: 5 of 29 1.1 Introduction The purpose of the Hearing Aid Compatibility is to enable measurements of the near electric fields generated by wireless communication devices in the region controlled for use by a hearing aid in accordance with ANSIC63.19-2019. The purpose of this standard is to establish categories for hearing aids and for WD (wireless communications devices) that can indicate to health care practitioners and hearing aid users which hearing aids are compatible with which WD, and to provide tests that can be used to assess the electromagnetic characteristics of hearing aids and WD and assign them to these categories. The various parameters required, in order to demonstrate compatibility and accessibility are measured. The design of the standard is such that when a hearing aid and WD achieve one of the categories specified, as measured by the methodology of this standard, the indicated performance is realized. In order to provide for the usability of a hearing aid with a WD, several factors must be coordinated: a) Radio frequency (RF) measurements of the near-field electric fields emitted by a WD to categorize these emissions for correlation with the RF immunity of a hearing aid. Hence, the following are measurements made for the WD: RF E-Field emissions The measurement plane is parallel to, and 1.5cm in front of, the reference plane. Applications for certification of equipment operation under part 20, that a manufacturer is seeking to certify as hearing aid compatible, as set forth in §20.19 of that part, shall include a statement indication compliance with the test requirements of §20.19 and indicating the appropriate U-rating for the equipment. The manufacturer of the equipment shall be responsible for maintaining the test results. 1.2 Details of Client Applicant: Address: Manufacturer: Address: COOSEA GROUP (HK) COMPANY LIMITED UNIT 5-6 16/F MULTIFIELD PLAZA 3-7A PRAT AVENUE TSIMSHATSUI KL COOSEA GROUP (HK) COMPANY LIMITED UNIT 5-6 16/F MULTIFIELD PLAZA 3-7A PRAT AVENUE TSIMSHATSUI KL 1.3 Test Location Company: SGS-CSTC Standards Technical Services (Suzhou) Co., Ltd.

Report No.: SEWM2311000466RG10 Rev.: 01 Page: 17 of 29 7 Modulation Interference Factor For any specific fixed and repeatable modulated signal, a modulation interference factor (MIF, expressed in dB) may be developed that relates its interference potential to its steady-state rms signal level or average power level. This factor is a function only of the audio-frequency amplitude modulation characteristics of the signal and is the same for field-strength and conducted power measurements. It is important to emphasize that the MIF is valid only for a specific repeatable audio-frequency amplitude modulation characteristic. Any change in modulation characteristic requires determination and application of a new MIF The Modulation Interference factor (MIF, in dB) is added to the measured average E-field (in dBV/m) and converts it to the RF Audio Interference level (in dBV/m). This level considers the audible amplitude modulation components in the RF E-field. CW fields without amplitude modulation are assumed to not interfere with the hearing aid electronics. Modulations without time slots and low fluctuations at low frequencies have low MIF values, TDMA modulations with narrow transmission and repetition rates of few 100 Hz have high MIF values and give similar classifications as ANSI C63.19-2019. DASY8 is therefore using the indirect measurement method according to ANSI C63.19-2019 which is the primary method. These near field probes read the averaged E-field measurement. Especially for the new high peak-toaverage (PAR) signal types, the probes shall be linearized by PMR calibration in order to not overestimate the field reading. Probe Modulation Response (PMR) calibration linearizes the probe response over its dynamic range for specific modulations which are characterized by their UID and result in an uncertainty specified in the probe calibration certificate. The MIF is characteristic for a given waveform envelope and can be used as a constant conversion factor if the probe has been PMR calibrated. The evaluation method for the MIF is defined in ANSI C63.19-2019 section D.7. An RMS demodulated RF signal is fed to a spectral filter (similar to an A weighting filter) and forwarded to a temporal filter acting as a quasi-peak detector. The averaged output of these filtering is scaled to a 1 kHz 80% AM signal as reference. MIF measurement requires additional instrumentation and is not well suited for evaluation by the end user with reasonable uncertainty. It may alliteratively be determined through analysis and simulation, because it is constant and characteristic for a communication signal. DASY8 uses well-defined signals for PMR calibration. The MIF of these signals has been determined by simulation and it is automatically applied. The MIF measurement uncertainty is estimated as follows, declared by HAC equipment provider SPEAG, for modulation frequencies from slotted waveforms with fundamental frequency and at least 2 harmonics within 10 kHz: 1. 0.2 dB for MIF: -7 to +5 dB 2. 0.5 dB for MIF: -13 to +11 dB 3. 1 dB for MIF: > -20 dB MIF values applied in this test report were provided by the HAC equipment provider of SPEAG, and the worst values for all air interface are listed below to be determine the Low-power Exemption.

Transiently occurring start-up, changeover, or termination conditions, or other operations likely to occur less than 1% of the time during normal operation, may be excluded from consideration. d) The center subgrid shall be centered on the T-Coil mode perpendicular measurement point or the acoustic output, as appropriate. Locate the field probe at the initial test position in the 50 mm by 50 mm grid, which is contained in the measurement plane, refer to illustrated in Figure 3. If the field alignment method is used, align the probe for maximum field reception. e) Record the reading at the output of the measurement system. f) Scan the entire 50 mm by 50 mm region in equally spaced increments and record the reading at each measurement point. The distance between measurement points shall be sufficient to assure the identification of the maximum reading. g) Identify the five contiguous subgrids around the center subgrid whose maximum reading is the lowest of all available choices. This eliminates the three subgrids with the maximum readings. Thus, the six areas to be used to determine the WD's highest emissions are identified. h) Identify the maximum reading within the nonexcluded subgrids identified in step g). i) Convert the maximum reading identified in step h) to RF audio interference level, in, V/m, by taking the square root of the reading and then dividing it by the measurement system transfer function, established in 5.5.1.1. Convert the result to dB(V/m) by taking the base-10 logarithmand multiplying it by 20. Indirect measurement method Replacing step i) of 5.5.1.2, the RF audio interference level in dB(V/m) is obtained by adding the MIF (in dB) to the maximum steady-state rms field-strength reading, in dB(V/m), from step h). Use this result to determine the category rating. j) Compare this RF audio interference level with the categories in Clause 8 and record the resulting WD category rating. k) For the T-Coil mode M-rating assessment, determine whether the chosen perpendicular measurement point is contained in an included subgrid of the first scan. If so, then a second scan is not necessary. The first scan and resultant category rating may be used for the T-Coil mode M rating. Otherwise, repeat step a) through step i), with the grid shifted so that it is centered on the perpendicular measurement point. Record the WD category rating. ` SGS-CSTC Standards Technical Services (Suzhou) Co., Ltd. 9 HAC RF Measurement Results 9.1 Max Tune-up Ant0 Frequency Band Channel GSM WCDMA FDD LTE 5G NR FDD 2.4GHz WLAN 5GHz WLAN GSM850 EDGE850 Band V HSPA Band 5 Band 12 Band 14 Band 17 Band 26 Band 71 n5 n26 n71 802.11b 802.11g 802.11n-HT20 802.11n-HT40 802.11a 802.11n-HT20 802.11n-HT40 802.11ac-VHT20 802.11ac-VHT40 802.11ac-VHT80 251 251 4233 4233 2060 23130 23330 23800 26965 133372 169800 169800 139600 6 6 6 6 40 40 40 40 40 40 Report No.: SEWM2311000466RG10 Rev.: 01 Page: 20 of 29 Frequency(MHz) 848.8 848.8 846.6 846.6 844 711 793 711 841.5 688 849 849 698 2437 2437 2437 2437 5200 5200 5200 5200 5200 5200 Average Power (dBm) 34.00 28.00 24.50 24.50 24.50 25.00 25.00 25.00 24.50 25.00 25.00 25.00 25.00 11.50 11.50 11.50 11.50 15.00 14.50 14.50 14.50 13.50 13.00 Frequency Band FDD LTE Band 2 Band 4 Band 30 Ant2 Channel 19100 20300 27710 Frequency(MHz) 1900 1745 2310 Average Power (dBm) 23.00 24.50 20.00 ` SGS-CSTC Standards Technical Services (Suzhou) Co., Ltd. 5G NR FDD 2.4GHz WLAN 5GHz WLAN Band 66 n2 n66 802.11b 802.11g 802.11n-HT20 802.11n-HT40 802.11a 802.11n-HT20 802.11n-HT40 802.11ac-VHT20 802.11ac-VHT40 802.11ac-VHT80 Frequency Band GSM WCDMA FDD LTE 5G NR FDD 5G NR TDD 2.4GHz WLAN 5GHz WLAN GSM1900 EDGE1900 Band II HSPA Band 2 Band 4 Band 30 Band 66 n2 n25 n30 n66 n70 n41 802.11b 802.11g 802.11n-HT20 802.11n-HT40 802.11a 802.11n-HT20 132572 382000 356000 6 6 6 6 40 40 40 40 40 40 Report No.: SEWM2311000466RG10 Rev.: 01 Page: 21 of 29 1770 24.50 1910 18.50 1780 25.00 2437 11.50 2437 11.50 2437 11.50 2437 11.50 5200 15.00 5200 14.50 5200 14.50 5200 14.50 5200 13.50 5200 13.00 Ant3 Channel 810 810 9538 9538 19100 20300 27710 132572 382000 383000 463000 356000 342000 528000 6 6 6 6 40 40 Frequency(MHz) 1909.8 1909.8 1907.6 1907.6 1900 1745 2310 1770 1910 1915 2315 1780 1710 2640 2437 2437 2437 2437 5200 5200 Average Power (dBm) 24.50 20.50 16.00 16.00 17.00 18.00 21.00 18.00 18.00 18.00 21.00 18.00 19.50 19.00 11.50 11.50 11.50 11.50 15.00 14.50 ` SGS-CSTC Standards Technical Services (Suzhou) Co., Ltd. 802.11n-HT40 802.11ac-VHT20 802.11ac-VHT40 802.11ac-VHT80 Frequency Band TDD LTE 5G NR TDD 2.4GHz WLAN 5GHz WLAN Band 48 n48 n77 802.11b 802.11g 802.11n-HT20 802.11n-HT40 802.11a 802.11n-HT20 802.11n-HT40 802.11ac-VHT20 802.11ac-VHT40 802.11ac-VHT80 Report No.: SEWM2311000466RG10 Rev.: 01 Page: 22 of 29 40 5200 14.50 40 5200 14.50 40 5200 13.50 40 5200 13.00 Ant4 Channel 56640 646666 662000 6 6 6 6 40 40 40 40 40 40 Frequency(MHz) 3690 3699.99 3930 2437 2437 2437 2437 5200 5200 5200 5200 5200 5200 Average Power (dBm) 21.00 18.00 18.00 11.50 11.50 11.50 11.50 15.00 14.50 14.50 14.50 13.50 13.00 ` SGS-CSTC Standards Technical Services (Suzhou) Co., Ltd.

The waveform-specific modulation interference factor (MIF) is measured separately and added to the measured average conducted power, in dBm. The WD's conducted power must be at or below either the stated RFAIPL (Table 4.1) or the stated peak power level (Table 4.2), or the average near-field emissions over the measurement area must be at or below the stated RFAIL (Table 4.3), or the stated peak field strength (Table 4.4). The WD may demonstrate compliance by meeting any of these four requirements, but it must do so in each of its operating bands at its established worst-case normal speech-mode operating condition. ` SGS-CSTC Standards Technical Services (Suzhou) Co., Ltd.
