FCC HAC (T-Coil) Test Report 3.2 System Calibration For correct and calibrated measurement of the voltages and ABM field, DASY will perform a calibration job as below. In phase 1, the audio output is switched off, and a 200 mVpp symmetric rectangular signal of 1 kHz is generated and internally connected directly to both channels of the sampling unit (Coil in, Probe in). In phase 2, the audio output is off, and a 20 mVpp symmetric 100 Hz signal is internally connected. The signals during phases 1 and 2 are available at the output on the rear panel of the AMMI. However, the output must not be loaded, in order to avoid influencing the calibration. An RMS voltmeter would indicate 100 mVRMS during the first phase and 10 mVRMS during the second phase. After the first two phases, the two input channels are both calibrated for absolute measurements of voltages. The resulting factors are displayed above the multi-meter window. After phases 1 and 2, the input channels are calibrated to measure exact voltages. This is required to use the inputs for measuring voltages with their peak and RMS value. In phase 3, a multi-sine signal covering each third-octave band from 50 Hz to 10 kHz is generated and applied to both audio outputs. The probe should be positioned in the center of the AMCC and aligned in the z-direction, the field orientation of the AMCC. The “Coil In” channel is measuring the voltage over the AMCC internal shunt, which is proportional to the magnetic field in the AMCC. At the same time, the “Probe In" channel samples the amplified signal picked up by the probe coil and provides it to a numerical integrator. The ratio of the two voltages in each third-octave filter leads to the spectral representation over the frequency band of interest. The Coil signal is scaled in dBV, and the Probe signal is first integrated and normalized to show dB A/m. The ratio probe-to-coil at the frequency of 1 kHz is the sensitivity which will be used in the consecutive T-Coil jobs.

FCC HAC (T-Coil) Test Report 3.3 EUT Measurements Reference and Plane The EUT is mounted in the device holder. The acoustic output of the EUT will coincide with the center point of the area formed by the dielectric wire and the middle bar of the arch’s top frame. Then EUT will be moved vertically upwards until it touches the frame. Figure 3.5 illustrates the three standard probe orientations. Position 1 is the perpendicular (axial) orientation of the probe coil. Orientation 2 is the transverse (radial) orientation. The space between the measurement positions is not fixed. It is recommended that a scan of the EUT be done for each probe coil orientation and that the maximum level recorded be used as the reading for that orientation of the probe coil. (1) The reference plane is 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 that, in normal handset use, rest against the ear. (2) The measurement plane is parallel to, and 10 mm in front of the reference plane. (3) The reference axis is normal to the reference plane and passes through the center of the receiver speaker section or it may be centered on a secondary inductive source. (4) The measurement points may be located where the perpendicular (axial) and transverse (radial) field intensity measurements are optimum with regard to the requirements. However, the measurement points should be near the acoustic output of the EUT and shall be located in the same half of the phone as the EUT receiver. In a EUT handset with a centered receiver and a circularly symmetrical magnetic field, the measurement axis and the reference axis would coincide. (5) The relative spacing of each measurement orientations is not fixed. The perpendicular (axial) and transverse (radial) orientations should be chosen to select the optimal position. (6) The measurement point for the axial position is located 10 mm from the reference plane on the measurement axis.

FCC HAC (T-Coil) Test Report 3.4 HAC T-Coil Measurement Procedure According to ANSI C63.19-2011, the T-Coil test procedure for wireless communications device is as below. 1. Position the EUT in the test setup and connect the EUT RF connector to a base station simulator. 2. The drive level to the EUT is set such that the reference input level specified in Table 7.1 is input to the base station simulator in the 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 7.4.2, shall be used for the reference audio signal. If interference is found at 1025 Hz, an alternate nearby reference audio signal frequency may be used. The same drive level will be used for the ABM1 frequency response measurements at each 1/3 octave band center frequency. The EUT 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. 3. Determine the magnetic measurement locations for the EUT, if not already specified by the manufacturer, as described in 7.4.4.1.1 and 7.4.4.2. 4. At each measurement location, measure and record the desired T-Coil magnetic signals (ABM1 at fi) as described in 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 Step 2 and the reading taken for that band. 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 or half-band integrated probe output, as described 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.) 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 criterion in 7.3.1. 5. At the measurement location for each orientation, measure and record the undesired broadband audio magnetic signal (ABM2) as described in 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). 6. Determine the category that properly classifies the signal quality based on Table 8.5.

FCC HAC (T-Coil) Test Report 3.5 Audio Reference Input Level According to ANSI C63.19-2011 section 7.4.2.1, the normal speech input level for HAC T-coil tests shall be set to -16 dBm0 for GSM and WCDMA, and to -18 dBm0 for CDMA. The technical description below shows a possibility to evaluate and set the correct level with the HAC T-Coil setup with a Rohde&Schwarz communication tester CMU200 with codec. Establish a call from the CMU200 to a wireless device. Select CMU200 Network Bitstream ”Decoder Cal” to obtain a 1 kHz signal from the internal generator with a level of 3.14 dBm0 at the speech output. Run the measurement job and read the voltage level at the multi-meter display RMS Coil signal. Read the RMS Coil signal voltage corresponding to 3.14 dBm0 and note it. Calculate the desired signal levels of -16 dBm0 and/or -18 dBm0. 3.14 dBm0 = X dBV -16 dBm0 = L-16dBm0 dBV L-16dBm0 = (-16) – (3.14) + X -18 dBm0 = L-18dBm0 dBV L-19dBm0 = (-18) – (3.14) + X Determine the 1 kHz gain level to generate the desired signal level of -16 dBm0 and/or -18 dBm0. Select CMU200 Network Bitstream “Encoder Cal” to loop the input via the codec to the output. Run the measurement job (AMMI 1 kHz signal with gain 10 inserted) and read the RMS voltage level at the multi-meter display RMS Coil signal. Calculate the required gain setting for the desired level. Gain 10 = G dBV Difference for -16 dBm0 = D-16dBm0 = L-16dBm0 – G Resulting Gain for -16 dBm0 = 10 ^ (D-16dBm0 / 20) * 10 Difference for -18 dBm0 = D-18dBm0 = L-18dBm0 – G Resulting Gain for -18 dBm0 = 10 ^ (D-18dBm0 / 20) * 10 The gain setting for other signal types need to be adjusted to achieve the same average level. Those signal types have the following differences/factors compared to the 1 kHz sine signal: Duration BWC Signal Type Required Gain Factor (s) (dB) 1 kHz sine - 0.0 1.00 48k_voice_1kHz 1 0.16 4.33 48k_voice_300-3000 2 10.8 8.48 Note: Gain Setting = Resulting Gain * Required Gain Factor The result of calculated gain setting is shown in section 4.3 of this report.

FCC HAC (T-Coil) Test Report 4. HAC Measurement Evaluation 4.1 Measurement Criteria The HAC Standard ANSI C63.19-2011 represents performance requirements for acceptable interoperability of hearing aids with wireless communications devices. When these parameters are met, a hearing aid operates acceptably in close proximity to a wireless communications device. 4.1.1 Field Intensity When measured as specified in this standard, the T-Coil signal shall be ≥ –18 dB (A/m) at 1 kHz, in a 1/3 octave band filter for all orientations. 4.1.2 Frequency Response The frequency response of the axial component of the magnetic field, measured in 1/3 octave bands, shall follow the below response curve, over the frequency range 300 Hz to 3000 Hz. Figure 4.1 and Figure 4.2 provide the boundaries for the specified 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.

FCC HAC (T-Coil) Test Report 4.1.3 Signal Quality The worst signal quality of the three T-Coil signal measurements shall be used to determine the T-Coil mode category per below table. Telephone Parameters WD Signal Quality Category (Signal to Noise Ratio, in dB) Category T1 0 – 10 Category T2 10 – 20 Category T3 20 – 30 Category T4 > 30 4.2 EUT Configuration and Setting For HAC T-Coil testing, the EUT was linked and controlled by base station emulator. Communication between the EUT and the emulator was established by coaxial connection. The EUT was set from the emulator to radiate maximum output power during HAC testing. 4.3 EUT Reference Level Calibration The predefined signal types have the following differences / factors compared to the 1 kHz sine signal: Audio Signal Measured Duration Gain Calculated Adjusted Level Signal Type / Desired (s) Factor Gain Setting Gain Setting (dBm0) Level (dBV) 3.14 1 kHz sine - 1.00 -2.52 - - -18 1 kHz sine - 1.00 -23.66 6.43 6.43 -18 48k_voice_1kHz 1 4.33 -23.66 27.84 27.83 -18 48k_voice_300-3000 2 8.48 -23.66 54.50 54.47 Note: 1. The gain setting for the voice signal (1 kHz and 300-3000 Hz) will be multiplied by the gain factor to achieve approximately the same level as for the 1 kHz sine signal. 2.

[2] ANSI—C63.19—2011 American National Standard, Methods of Measurement of Compatibility between Wireless Communications Devices and Hearing Aids. [3] DASYS5 manual, Chapter: Hearing Aid Compatibility (HAC) T—Coil Extension Description of the AM1D probe The AM1D Audio Magnetic Field Probe is a fully shielded magnetic field probe for the frequency range from 100 Hz to 20 kHz. The pickup coil is compliant with the dimensional requirements of [1+2]. The probe includes a symmetric low noise amplifier for the signal available at the shielded 3 pin connector at the side. Power is supplied via the same connector (phantom power supply) and monitored via the LED near the connector. The 7 pin connector at the end of the probe does not carry any signals, but determines the angle of the sensor when mounted on the DAE. The probe supports mechanical detection of the surface. The single sensor in the probe is arranged in a tilt angle allowing measurement of 3 orthogonal field components when rotating the probe by 120° around its axis. It is aligned with the perpendicular component of the field, if the probe axis is tilted nominally 35.3° above the measurement plane, using the connector rotation and sensor angle stated below. The probe is fully RF shielded when operated with the matching signal cable (shielded) and allows measurement of audio magnetic fields in the close vicinity of RF emitting wireless devices according to [1+2] without additional shielding. Handling of the item The probe is manufactured from stainless steel. In order to maintain the performance and calibration of the probe, it must not be opened. The probe is designed for operation in air and shall not be exposed to humidity or liquids. For proper operation of the surface detection and emergency stop functions in a DASY system, the probe must be operated with the special probe cup provided (larger diameter). Methods Applied and Interpretation of Parameters Coordinate System: The AM1D probe is mounted in the DASY system for operation with a HAC Test Arch phantom with AMCC Helmholtz calibration coil according to [3], with the tip pointing to "southwest" orientation. Functional Test: The functional test preceding calibration includes test of Noise level RF immunity (1kHz AM modulated signal). The shield of the probe cable must be well connected. Frequency response verification from 100 Hz to 10 kHz. Connector Rotation: The connector at the end of the probe does not carry any signals and is used for fixation to the DAE only. The probe is operated in the center of the AMCC Helmholtz coil using a 1 kHz magnetic field signal. Its angle is determined from the two minima at nominally +120° and — 120° rotation, so the sensor in the tip of the probe is aligned to the vertical plane in z—direction, corresponding to the field maximum in the AMCC Helmholtz calibration coil. Sensor Angle: The sensor tilting in the vertical plane from the ideal vertical direction is determined from the two minima at nominally +120° and —120°. DASY system uses this angle to align the sensor for radial measurements to the x and y axis in the horizontal plane. Sensitivity: With the probe sensor aligned to the z—field in the AMCC, the output of the probe is compared to the magnetic field in the AMCC at 1 kHz. The field in the AMCC Helmholtz coil is given by the geometry and the current through the coil, which is monitored on the precision shunt resistor of the coil.
