ER3DV6 Isotropic E-Field Probe Construction: One dipole parallel, two dipoles normal to probe axis Built-in shielding against static charges PEEK enclosure material (resistant to organic solvents, e.g., glycolether) Calibration: In air from 100 MHz to 3.0 GHz (absolute accuracy ±6.0%, k=2) Frequency: 100 MHz to > 6 GHz; Linearity: ± 0.2 dB (100 MHz to 3 GHz) Directivity: ± 0.2 dB in air (rotation around probe axis) ± 0.4 dB in air (rotation normal to probe axis) Dynamic Range: 2 V/m to > 1000 V/m; Linearity: ± 0.2 dB Dimensions: Overall length: 330 mm (Tip: 16 mm) Tip diameter: 8 mm (Body: 12 mm) Distance from probe tip to dipole centers: 2.5 mm The closest part of the sensor element is 1.1 mm closer to the tip Application: General near-field measurements up to 6 GHz Field component measurements Page 10 of 21 UL Verification Service Inc.

REPORT NO: 15I19834-S3 FCC ID: ZNFLS770 DATE: 2/18/2015 7. System Validation The test setup was validated when first configured and verified periodically thereafter to ensure proper function. The procedure provided in this section is a validation procedure using dipole antennas for which the field levels were computed by numeric modeling. Procedure Place a dipole antenna meeting the requirements given in ANSI C63.19-2011 in the normally occupied by the WD. The dipole antenna serves as a known source for an electrical and magnetic output. Position the E-field probe so that the following occurs: ‧ The probes and their cables are parallel to the coaxial feed of the dipole antenna ‧ The probe cables and the coaxial feed of the dipole antenna approach the measurement area from opposite directions ‧ The center point of the probe element(s) is 15 mm from the closest surface of the dipole elements. Scan the length of the dipole with the E-field probe and record the two maximum values found near the dipole ends. Average the two readings and compare the reading to the expected value in the calibration certificate or the expected value in this standard. Setup diagram Page 11 of 21 UL Verification Service Inc.

REPORT NO: 15I19834-S3 FCC ID: ZNFLS770 DATE: 2/18/2015 8. Modulation Interference Factor (MIF) The HAC Standard ANSI C63.19-2011 defines a new scaling using the Modulation Interference Factor (MIF) which replaces the need for the Articulation Weighting Factor (AWF) during the evaluation and is applicable to any modulation scheme. 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 C63-2007. Definitions ER3D, E-field probes have a bandwidth <10 kHz and can therefore not evaluate the RF envelope in the full audio band. DASY52 is therefore using the “indirect” measurement method according to ANSI C63.19-2011 which is the primary method. These near field probes read the averaged E-field measurement. Especially for the new high peak- to-average (PAR) signal types, the probes shall be linearized by probe modulation response (PMR) calibration in order to not overestimate the field reading. The evaluation method or the MIF is defined in ANSI C63.19-2011 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 called 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 alternatively be determined through analysis and simulation, because it is constraint and characteristic for a communication signal. DASY52 uses well defined signals for PMR calibration. The MIF of these signals has been determined by simulation and is automatically applied. MIF values were not tested by a probe or as specified in the standards but are based on analysis provided by SPEAG for all the air interfaces (GSM, WCDMA, CDMA, LTE). The data included in this report are for the worst case operating modes. The UIDs used are listed below: UID Communication System Name MIF (dB) th 10295-AAB CDMA2000 (1xRTT, RC1, SO3, 1/8 Rate 25 fr.) 3.26 10170-CAB LTE-FDD (SC-FDMA, 1 RB, 20 MHz, 16QAM) -9.76 10182-CAB LTE-FDD (SC-FDMA, 1 RB, 15 MHz, 16QAM) -9.76 10176-CAB LTE-FDD (SC-FDMA, 1 RB, 10 MHz, 16QAM) -9.76 10173-CAB LTE-TDD (SC-FDMA, 1 RB, 20 MHz, 16QAM) -1.44 A PMR calibrated probe is linearized for the selected waveform over the full dynamic range within the uncertainty specified in its calibration certificate. ER3D, EF3D and EU2D E-field probes have a bandwidth <10 kHz and can therefore not evaluate the RF envelope in the full audio band. DASY52 is therefore using the \indirect" measurement method according to ANSI C63.19-2011 which is the primary method. These near field probes read the averaged E- field measurement. Especially for the new high peak-to-average (PAR) signal types, the probes shall be linearized by PMR calibration in order to not overestimate the field reading. The MIF measurement uncertainty is estimated as follows, for modulation frequencies from slotted waveforms with fundamental frequency and at least 2 harmonics within 10 kHz:  0.2 dB for MIF -7 to +5 dB,  0.5 dB for MIF -13 to +11 dB  1 dB for MIF > -20 dB Page 13 of 21 UL Verification Service Inc.

REPORT NO: 15I19834-S3 FCC ID: ZNFLS770 DATE: 2/18/2015 11. HAC RF Emissions Test Procedure The following are step-by-step test procedures. a) Confirm proper operation of the field probe, probe measurement system and other instrumentation and the positioning system. b) Position the WD in its intended test position. c) Set the WD to transmit a fixed and repeatable combination of signal power and modulation characteristic that is representative of the worst case (highest interference potential) encountered in normal use. 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 sub-grid 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 1. 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 sub-grids around the center sub-grid whose maximum reading is the lowest of all available choices. This eliminates the three sub-grids 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 non-excluded sub-grids identified in step g). i) Convert the highest field reading within 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 this result to dB(V/m) by taking the base-10 logarithm and multiplying by 20. Indirect measurement method Replacing step i), 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 (ANSI C63.19-2011) 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 sub-grid 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.
