pre-installed on a wireless handset by the Zebra Technologies Corporation. 3. The WiFi 6E above 6GHz portion is currently not within the scope of ANSI C63.19 and FCC HAC regulations therefore they were not
evaluated. 4. The device have similar frequency in some LTE bands: LTE 4/66, 38/41 and NR Band n38/41, 77/78, since the supported frequency spans
for the smaller LTE bands are completely cover by the larger LTE bands, therefore, only larger LTE bands were required to be tested for hearing-aid compliance. 5. Because features of Google Duo allow the option of voice-only communications, Duo has been tested for HAC/T-Coil compatibility to ensure the best user experience.

6. Measurement standards for T-Coil

Report No. : HA271545B

6.1 Frequency Response

The frequency response of the perpendicular component of the magnetic field, measured in 1/3 octave bands, shall follow the response curve specified in this sub-clause, over the frequency range 300 Hz to 3000 Hz. Figure 1.1 and Figure 1.2 provide the boundaries as a function of frequency. These response curves are for true field-strength measurements of the T-Coil signal. Thus, the 6 dB/octave probe response has been corrected from the raw readings.

Fig. 1.1 Magnetic field frequency response for WDs with field strength-15dB at 1 KHz

Fig. 1.2 Magnetic field frequency response for WDs with a field that exceeds ­15 dB(A/m) at 1 kHz

6.2 T-Coil Signal Quality Categories
This section provides the signal quality requirement for the intended T-Coil signal from a WD. Only the RF immunity of the hearing aid is measured in T-Coil mode. It is assumed that a hearing aid can have no immunity to an interference signal in the audio band, which is the intended reception band for this mode. A device is assessed beginning by determining the category of the RF environment in the area of the T-Coil source. The RF measurements made for the T-Coil evaluation are used to assign the category T1 through T4. The limitation is given in Table 1. This establishes the RF environment presented by the WD to a hearing aid.

Report No. : HA271545B

Fig.3 illustrate the references and reference plane that shall be used in a typical EUT emissions measurement. The principle of this section is applied to EUT with similar geometry. Please refer to Appendix C for the setup photographs.

 The area is 5 cm by 5 cm.  The area is centered on the audio frequency output transducer of the EUT.  The area is in a reference plane, which is defined as the planar area that contains the highest point
in the area of the phone that normally rests against the user's ear. It is parallel to the centerline of the receiver area of the phone and is defined by the points of the receiver-end of the EUT handset, which, in normal handset use, rest against the ear.  The measurement plane is parallel to, and 10 mm in front of, the reference plane.

HAC T-COIL TEST REPORT
7. T-Coil Test Procedure

Report No. : HA271545B

Referenced to ANSI C63.19-2011, Section 7.4 This section describes the procedures used to measure the ABM (T-Coil) performance of the WD. In addition to measuring the absolute signal levels, the A-weighted magnitude of the unintended signal shall also be determined. To assure that the required signal quality is measured, the measurement of the intended signal and the measurement of the unintended signal must be made at the same location for each measurement position. In addition, the RF field strength at each measurement location must be at or below that required for the assigned category. Measurements shall not include undesired properties from the WD's RF field; therefore, use of a coaxial connection to a base station simulator or non-radiating load, there might still be RF leakage from the WD, which can interfere with the desired measurement. Pre-measurement checks should be made to avoid this possibility. All measurements shall be performed with the WD operating on battery power with an appropriate normal speech audio signal input level given in ANSI C63.19-2011 Table 7.1. If the device display can be turned off during a phone call, then that may be done during the measurement as well, Measurement shall be performed at two locations specified in ANSI C63.19-2011 A.3, with the correct probe orientation for a particular location, in a multistage sequence by first measuring the field intensity of the desired T-Coil signal the same location as the desired ABM or T-Coil signal (ABM1), and the ratio of desired to undesired magnetic components (ABM2) must be measured at the same location as the desired ABM or T-Coil signal (ABM1), and the ratio of desired to undesired ABM signals must be calculated. For the perpendicular field location, only the ABM1 frequency response shall be determined in a third measurement stage. The following steps summarize the basic test flow for determining ABM1 and ABM2. These steps assume that a sine wave or narrowband 1/3 octave signal can be used for the measurement of ABM1. a. A validation of the test setup and instrumentation may be performed using a TMFS or Helmholtz coil Measure
the emissions and confirm that they are within the specified tolerance. b. Position the WD in the test setup and connect the WD RF connector to a base station simulator or a
non-radiating load. Confirm that equipment that requires calibration has been calibrated, and that the noise level meets the requirements given in ANSI C63.19-2011 clause 7.3.1. c. The drive level to the WD ise set such that the reference input level specified in ANSI C63.19-2011 Table 7.1 is input to the base station simulator (or manufacturer's test mode equivalent) in 1 kHz, 1/3 octave band. This drive level shall be used for the T-Coil signal test (ABM1) at f = 1 kHz. Either a sine wave at 1025 Hz or a voice-like signal, band-limited to the 1 kHz 1/3 octave, as defined in ANSI C63.19-2011 clause 7.4.2, shall be used for the reference audio signal. If interference is found at 1025 Hz an alternative nearby reference audio signal frequency may be used. The same drive level shall be used for the ABM1 frequency response measurements at each 1/3 octave band center frequency. The WD volume control may be set at any level up to maximum, provided that a signal at any frequency at maximum modulation would not result in clipping or signal overload. d. Determine the magnetic measurement locations for the WD device (A.3), if not already specified by the manufacturer, as described in ANSI C63.19-2011 clause 7.4.4.1.1 and 7.4.4.2. e. At each measurement location, measure and record the desired T-Coil magnetic signals (ABM1 at fi) as described in ANSI C63.19-2011 clause 7.4.4.2 in each individual ISO 266-1975 R10 standard 1/3 octave band. The desired audio band input frequency (fi) shall be centered in each 1/3 octave band maintaining the same drive level as determined in item c) and the reading taken for that band. f. Equivalent methods of determining the frequency response may also be employed, such as fast Fourier transform (FFT) analysis using noise excitation or input-output comparison using simulated speech. The full-band integrated probe output, as specified in D.9, may be used, as long as the appropriate calibration curve is applied to the measured result, so as to yield an accurate measurement of the field magnitude. (The resulting measurement shall be an accurate measurement in dB A/m.) g. All Measurements of the desired signal shall be shown to be of the desired signal and not of an undesired signal. This may be shown by turning the desired signal ON and OFF with the probe measuring the same location. If the scanning method is used the scans shall show that all measurement points selected for the ABM1 measurement meet the ambient and test system noise criteria in ANSI C63.19-2011 clause 7.3.1. h. At the measurement location for each orientation, measure and record the undesired broadband audio magnetic signal (ABM2) as specified in ANSI C63.19-2011 clause 7.4.4.4 with no audio signal applied (or digital zero applied, if appropriate) using A-weighting and the half-band integrator. Calculate the ratio of the desired to undesired signal strength (i,e., signal quality). i. Obtain the data from the postprocessor, SEMCAD, and determine the category that properly classifies the signal quality based on ANSI C63.19-2011 Table 8.5.

Report No. : HA271545B

General Note: 1. Define the all applicable input audio level as below according to C63 and KDB 285076 D02:
- GSM input level: -16dBm0 - UMTS input level: -16dBm0 - CDMA input level: -18dBm0 - VoLTE input level: -16dBm0 - VoWiFi input level: -20dBm0 2. For GSM / UMTS / CDMA test setup and input level, the correct input level definition is via a communication tester CMU200's "Decoder Cal" and "Codec Cal" with audio option B52 and B85 to set the correct audio input levels. 3. CMU200 is able to output 1kHz audio signal equivalent to 3.14dBm0 at "Decoder Cal." confuguration, the signal reference is used to adjust the AMMI gain setting to reach -16dBm0 for GSM/UMTS and -18dBm0 for CDMA. CMW500 input is calibrated and the relation between the analog input voltage and the internal level in dBm0 can be determined 4. Voice over Long-Term Evolution (VoLTE) is a standard for high-speed wireless communication for mobile phones and data terminals -- including IoT devices and wearables. It is based on the IP Multimedia Subsystem (IMS) network, with specific profiles for control and media planes of voice service on LTE defined by GSMA in PRD IR.92. This approach results in the voice service (control and media planes) being delivered as data flows within the LTE data bearer. This means that there is no dependency on the legacy circuit-switched voice network to be maintained 5. The test setup used for VoLTE and VoWiFI over IMS is via the callbox of CMW500 for T-coil measurement, The data application unit of the CMW500 was used to simulate the IP multimedia subsystem server. The CMW500 can be manually configured to ensure and control the speech input level result is -16dBm0 for VoLTE, -20dBm0 for VoWiFi when the device during the IMS connection. 6. According to KDB 285076 D02, T-Coil testing for VoLTE and VoWiFi requires test instrumentation that can (1) for the system to be able to establish an IP call from/to the handset under test, (2) through an IMS (IP Multimedia Subsystem) and SIP/IP server, (3) to an analog audio adapter containing the permissible set of codecs used by the device under test, and (4) inject the necessary C63.19 test tones at the average speech level for the measurement The test setup is illustrated in Figure 3.9. The R&S CMW500 was used as system simulator for VoLTE and VoWiFi T-Coil testing. The DAU (Data Application Unit) in CMW500 integrates IMS and SIP/IP server that can establish VoLTE and Wi-Fi calling, and transport the test tones from AMMI (Audio Magnetic Measuring Instrument) to EUT. 7. T-coil performance assessment for 5G FR1 was performed according to KDB 285076 D03, Q&A 9, details are illustrated in section 7.4.

General Note: 1. Define the all applicable input audio level as below according to C63 and KDB 285076 D02v03:
- OTT Voice calling input Level: -20dBm0 2. OTT voice, such as that enabled when a user opts to communicate in a voice-only mode using the Google Duo application, is a
methodology and group of technologies for the delivery of voice communications and multimedia sessions over the internet. The terms Internet telephony, broadband telephony, and broadband phone service specifically refer to the provisioning of communications services (voice, fax, SMS, voice-messaging) over the public Internet, rather than via the public switched telephone network (PSTN). 3. Google Duo application support code and bitrate are listed in section 11, and the customized Google Duo software is installed on a mobile phone that is used as the Auxiliary for the test. The software enables the audio coding rate to be changed, and reports the input digital audio level before audio processing, which can be used to calibrate the input audio level. 4. This device comes with the preinstalled OTT application that supports the voice-only communication option on the Google Duo application and related codec. The test configuration establishes a call between the device under test and an auxiliary handset via Google Duo server. 5. The test setup used for Google Duo OTT voice-only communication is via the data application unit on the simulate base station, connected to the internet via the Google Duo server to the auxiliary device. The auxiliary device runs special software that allows the codecs and bit rate to be fixed to a specific value. Please refer to section 11. An assessment was made of each of the different codec bit rates to determine the worst case for each different OTT transport (WiFi, LTE, GSM, WCDMA). 6. The auxiliary device includes software that displays the audio level in dBFS, which allows calibration of the system to establish the -20dBm0 reference level. After establishing the voice-only communication between auxiliary device and device under test, the audio output from the AMMI is injected into the auxiliary device. The gain factor to establish a reference level of -20dBm0 for use during the test is determined as detailed in the next page based on the 0dBFull Scale (0dBFS) value being equivalent to 3.14dBm0. 7. T-coil performance assessment for 5G FR1 was performed according to KDB 285076 D03 v01r04, Q&A 9, details are illustrated in section 7.4.

9. T-Coil testing for CMRS Voice

General Note: 1. Codec Investigation: For a voice service/air interface, investigate the variations of codec configurations (WB, NB bit
rate) and document the parameters (ABM1, ABM2, S+N/N, frequency response) for that voice service. It is only necessary to document this for one channel/band, the following worst investigation codec would be remarked to be used for the testing for the handset. 2. Air Interface Investigation: a. Use the worst-case codec test and document a limited set of bands/channel/bandwidths. Observe the effect of
changing the band and bandwidth to ensure that there are no unexpected variations. Using the knowledge of the observed variations, it is necessary to report only a set band/channel/bandwidth for each orientation for a voice service/air interface. b. According to the ANSI C63.19 2011 section 7.3.2, test middle channel of each frequency band for HAC testing for each orientation to determine worst HAC T-Coil rating.

HAC T-COIL TEST REPORT
11. T-Coil testing for OTT Voice Calling

Report No. : HA271545B

General Notes: 1. According to the ANSI C63.19 2011 section 7.3.2, test middle channel of each frequency band for HAC testing for
each orientation to determine worst HAC T-Coil rating. 2. The device supported a pre-installed application, Google Duo, whose features allow the option of voice-only
communications. According to KDB 285076 D02, all air interfaces via a data connection with an application providing voice functionality need to be considered for HAC testing. 3. The google Duo and WFC VoIP application are pre-installed on this device. According to KDB 285076 D02, all air interfaces via a data connection with VoIP application need to be considered HAC testing. 4. The Google Duo only support OPUS audio codec and support 6Kbps to 75Kbps bitrate and the WFC support G.729/GSM13Kbit/G.722/PCMA64Kbit/PCMU64Kbit codec are list as below table Google Duo only support OPUS audio codec and support 6Kbps to 75Kbps bitrate. 5. The test setup used for OTT Voice call is the DUT connect to the CMW500 and via the data application unit on CMW500 connection to the Internet, the Auxiliary EUT is connected to the WiFi access point, the channel/Modulation/Frequency bands/data rate is configured on the CMW500 for the DUT unit. For the Auxiliary OTT unit which is used to configure the audio codec rate and determine the audio input level of -20dBm0 based on the KDB 285076 D02 requirement. 6. Codec Investigation: For a voice service/air interface, investigate the variations of codec configurations (WB, NB bit rate) and document the parameters (ABM1, ABM2, S+N/N, frequency response) for that voice service. It is only necessary to document this for one channel/band, the following tests results which the worst case codec would be remarked to be used for the testing for the handset. 7. Air Interface Investigation: a. Use the worst-case codec test and document a limited set of bands/channel/bandwidths. Observe the effect of
changing the band and bandwidth to ensure that there are no unexpected variations. Using the knowledge of the observed variations, it is necessary to report only a set band/channel/bandwidth for each orientation for a voice service/air interface. b. Select WLAN 2.4GHz and WLAN 5GHz one frequency band to do measurement at the worst SNR position was additionally performed with varying the BWs/Modulations/data rate to verify the variation to find out worst configuration , the observed variation is very little to be within 1 dB which is much less than the margin from the rating threshold. c. Due to OTT service and CMRS IP service are all be established over the internet protocol for the voice service, and on both services use the identical RF air interface for the LTE, therefore according to VoLTE test results of air interface investigation, the worst configuration and frequency band of air interface was used for OTT T-Coil testing. -LTE FDD worst configuration and band: LTE Band 2/20MHz/QPSK/1RB Size -LTE TDD worst configuration and band: LTE Band 42/20MHz/QPSK/1RB Size

HAC T-COIL TEST REPORT 11.15G FR1 OTT evaluation

Report No. : HA271545B

General Notes: 1. According to KDB 285076 D03, for 5G Sub 6 calls that use the same protocol, Codec(s) and reference level as OTT
calls (such as Duo or AppleTalk). 2. Due to OTT service and CMRS IP service are all be established over the internet protocol for the voice service, and
on both services use the identical RF air interface for the 5G NR, therefore according to VoNR test results of air interface investigation, the worst configuration and frequency band of air interface was used for OTT T-Coil testing.
-NR FDD worst configuration and band: NR band 2/20MHz/BPSK/1RB Size -NR TDD worst configuration and band: NR band 77/100MHz/BPSK/1RB Size 3. For LTE, establish the ABM1S65G value by using the ABM1LTE magnetic intensity for an LTE call in the same band as the 5G sub6 band under test. 4. For OTT, establish the ABM1S65G value by using an IP connection for magnetic intensity for a call in the same band as the 5G sub6 band under test 5. Also note the actual ABM2LTE/OTT value and establish an ABM2S65G value, using a 5G manufacture test mode over 5G Sub 6 channels for the same band under test. 6. Document in the test report matrix: a. Include columns for both ABM2LTE & ABM2S65G for comparison b. Establish the S+N1/N2 for the rating
i. S+N1 = ABM1LTE (step 1) and ii. N2 = ABM2S65G (step 2). iii. Subtract 3 dB from S+N1/N2 c. Rating based on (ABM1LTE/ ABM2S65G) -3dB.

HAC T-COIL TEST REPORT
12. Uncertainty Assessment

Report No. : HA271545B

The evaluation of uncertainly by the statistical analysis of a series of observations is termed a Type A evaluation of uncertainty. The evaluation of uncertainty by means other than the statistical analysis of a series of observation is termed a Type B evaluation of uncertainty. Each component of uncertainty, however evaluated, is represented by an estimated standard deviation, termed standard uncertainty, which is determined by the positive square root of the estimated variance. The combined standard uncertainty of the measurement result represents the estimated standard deviation of the result. It is obtained by combining the individual standard uncertainties of both Type A and Type B evaluation using the usual "root-sum-squares" (RSS) methods of combining standard deviations by taking the positive square root of the estimated variances. Expanded uncertainty is a measure of uncertainty that defines an interval about the measurement result within which the measured value is confidently believed to lie. It is obtained by multiplying the combined standard uncertainty by a coverage factor. For purpose of this document, a coverage factor two is used, which corresponds to confidence interval of about 95 %. The DASY uncertainty Budget is showed in Table 8.2. The judgment of conformity in the report is based on the measurement results excluding the measurement uncertainty.
