SAR System Check Prior to SAR assessment, the system is verified to ±10% of the SAR measurement on the reference dipole at the time of calibration by the calibration facility. SAR System Validation was performed and complies with requirements per IEC/IEEE 62209-1528. Table 1 System Check Results (SAR) B.2. Dielectric Parameters of the TSL Table 2 SAR Tissue Dielectric Parameters The above measured tissue parameters were used in the DASY software. The DASY software was used to perform interpolation to determine the dielectric parameters at the SAR test device frequencies (per KDB Publication 865664 D01v01r04 and IEEE 1528-2013 6.6.1.2). The tissue parameters listed in the SAR test plots may slightly differ from the table above due to significant digit rounding in the software. The SAR values were compensated for deviations between the measured and required tissue dielectric properties, as described in IEEE 1528-2013. The SAR values were applied to only scale up the measured SAR values, and not downward, per KDB Publication 865664 D01v04r04. System Frequency (MHz) Tissue Type Date Amb. Temp.

FCC System Validation Per FCC KDB Publication 865664 D02 Section 2.3 a) states “SAR system validation status and system verification results should be documented in a separate section of the SAR report, or as an attachment, to confirm measurement accuracy.” The SAR systems used for evaluating this device were validated against its performance specifications prior to the SAR measurements. Reference dipoles were used with the required tissue-equivalent media for system validation, according to the procedures outlined in FCC KDB Publication 865664 D01 and IEEE 1528-2013. Since SAR probe calibrations are frequency dependent, each probe calibration point was validated at a frequency within the valid frequency range of the probe calibration point. Per FCC KDB 865664 D02, “the validation status should be documented according to the validation date(s), measurement frequencies, SAR probes, calibrated signal type(s) and tissue dielectric parameters.” A tabulated summary of the system validation status is provided accordingly: Table 3 System Validation NOTE: The probes have been calibrated for both CW and modulated signals. Modulations in the table above represent test configurations for which the measurement system has been validated per FCC KDB Publication 865664 D01 for scenarios when CW probe calibrations are used with other signal types. SAR systems were additionally validated for modulated signals with a periodic duty cycle or with a high PAR (peak to average ratio) >5 dB, such as OFDM according to FCC KDB Publication 865664 D01 v01r04.

Prior to testing, the measurement paths containing a cable, attenuator, coupler or filter were connected to a calibrated source (i.e. a signal generator, power sensor, or VNA) to determine the losses of the measurement path. The power meter offset was then adjusted to compensate for the measurement system losses. This level offset is stored within the power meter before measurements are made. This calibration verification procedure applies to the system verification and output power measurements. The calibrated reading is then taken directly from the power meter after compensation of the losses for all final power measurements.

Prior to testing, the measurement paths containing a cable, attenuator, coupler or filter were connected to a calibrated source (i.e. a signal generator, power sensor, or VNA) to determine the losses of the measurement path. The power meter offset was then adjusted to compensate for the measurement system losses. This level offset is stored within the power meter before measurements are made. This calibration verification procedure applies to the system verification and output power measurements. The calibrated reading is then taken directly from the power meter after compensation of the losses for all final power measurements.

Introduction According to FCC KDB Publication 447498 D04v01, transmitters are considered to be operating simultaneously when there is overlapping transmission, with the exception of transmissions during network hand-offs with maximum hand-off duration less than 30 seconds. Table E-1 - Supported Simultaneous Transmission Scenarios Note: NFC, WIFI, ANT/ANT+ are permanently disabled during all voice scenarios where the device may operating in front of the face. Therefore, no held to face scenario was required for standalone or simultaneous transmission analysis for these modes. E.2. Procedures This device contains transmitters that may operate simultaneously. Therefore, simultaneous transmission analysis is required. Per FCC KDB Publication 447498 D04v01 and IEEE 1528-2013 Section 6.3.4.1.2, simultaneous transmission SAR test exclusion may be applied when the sum of the 1g SAR for all the simultaneous transmitting antennas in a specific physical test configuration is ≤1.6 W/kg. The different test positions in an exposure condition may be considered collectively to determine SAR test exclusion according to the sum of 1g or 10g SAR. Unless otherwise noted, when 10g SAR measurement is considered, a factor of 2.5 is applied to the 1g thresholds for the equivalent test cases. E.3. ANT/ANT+ Estimated SAR E.3.1 FCC Estimated SAR Per FCC KDB 447498 D01 v06 Section 4.3.2, when an antenna qualifies for the standalone SAR test exemption and also 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: 푀푀푀푀푀푀푀푀푀푀푀푀푀푀푀푀 퐷퐷퐷퐷퐷퐷퐷퐷 푀푀퐷퐷퐷퐷푀푀 ∙ � 푓푓 퐺퐺퐺퐺퐺퐺 18.75 (for 10-g SAR) Where: 푓푓 퐺퐺퐺퐺퐺퐺 = RF Channel frequency in GHz MaxPower = Power of channel, including tune-up tolerance, rounded to the nearest mW before calculation Distance = Min. Test Separation Distance in mm, rounded to the nearest mm before calculation Per FCC KDB 447498 D01 v06 Section 4.3.1, “Power and distance are rounded to the nearest mW and mm before calculation.” The result is rounded to one decimal place for comparison. #ScenarioHead Extremity 12.4 GHz WIFI + NFCN/AYes 22.4 GHz Bluetooth + NFCN/AYes 32.4 GHz ANT/ANT+ + NFCN/AYes FCC ID: IPH-A5172 IC: 1792A-A5172 SAR-001: SAR Test Report RevA Test Report S/N: 2026.022.01 Page E2 of E3 For ANT/ANT+, 4.5 dBm + 2 dB = 6.5 dBm = 4 mW For distances ≤ 5mm, per FCC policy the value of 5 shall be used for the distance component of the equation. 푀푀푀푀푀푀푀푀푀푀푀푀푀푀푀푀 퐷퐷퐷퐷퐷퐷퐷퐷 푀푀퐷퐷퐷퐷푀푀 ∙ � 푓푓 퐺퐺퐺퐺퐺퐺 18.75 = 4 5 ∙ √ 2.48 18.75 = 0.1 W/kg (for 10-g SAR) ANT/ANT+ Estimated SAR is 0.1 W/kg for 10-g SAR. E.3.2 ISED Estimated SAR Per RSS-102 Section 7.1.8, an estimated SAR value based on the ratio of the power level and the power exemption limit may be used to determine the standalone SAR value for test configurations that do not require a SAR evaluation based on test reductions. The estimated SAR value is calculated using equation below: 푀푀 푚푚푚푚푚푚 푀푀 푚푚푚푚푚푚,푒푒푚푚푒푒 푚푚푒푒푒푒푒푒푒푒푒푒 ∙0. 25 .푆푆푆푆푆푆 푙푙퐷퐷푙푙퐷퐷퐷퐷 Where: 푃푃 푙푙푀푀푀푀 = maximum power level, including tune-up tolerance, in mW 푃푃 푙푙푀푀푀푀,푀푀푀푀푀푀푙푙푒푒 퐷퐷퐷퐷푀푀퐷퐷 = maximum power level of exemption, in mW 푆푆푆푆푆푆 푙푙퐷퐷푙푙퐷퐷퐷퐷 = applicable SAR limit for 1-g and 10-g SAR, in W/kg For ANT/ANT+, 4.5 dBm + 2 dB = 6.5 dBm = 4 mW Per RSS-102 Section 6.3, the maximum power level of exemption at frequency 2450 MHz and distance ≤ 5mm is 7.5 mW for 10-g SAR. 푀푀 푚푚푚푚푚푚 푀푀 푚푚푚푚푚푚,푒푒푚푚 푒푒푚푚 푒푒푒푒푒푒푒푒푒푒 ∙0.25 .푆푆푆푆푆푆 푙푙퐷퐷푙푙퐷퐷퐷퐷 = 4 7.5 x 0.25 x 4.0 = 0.5 W/kg (for 10-g SAR) ANT/ANT+ Estimated SAR is 0.5 W/kg for 10-g SAR. E.4. Simultaneous Transmission Analysis NFC, WIFI, ANT/ANT+ are permanently disabled during all voice scenarios where the device may operating in front of the face. Therefore, no held to face scenario was required for standalone or simultaneous transmission analysis for these modes. Therefore, no further analysis beyond the tables included in this section was required to determine that possible simultaneous transmission scenarios would not exceed the SAR limit. FCC ID: IPH-A5172 IC: 1792A-A5172 SAR-001: SAR Test Report RevA Test Report S/N: 2026.022.01 Page E3 of E3 Table E-2 – FCC Simultaneous Transmission Analysis Table E-3 – ISED Simultaneous Transmission Analysis The above analysis of the simultaneous transmission scenarios is sufficient to show that simultaneous transmission cases will not exceed the SAR limit. Therefore, no measured volumetric simultaneous SAR summation is required per FCC KDB Publication 447498 D04v01 and IEEE 1528- 2013 Section 6.3.4.1.
