The tissue was placed in a nonmetallic container. Trapped air bubbles beneath the flange were minimized by placing the probe at a slight angle. 3) The complex admittance with respect to the probe aperture was measured. 4) The complex relative permittivity εr can be calculated from the below equation (Pournaropoulos and Misra): Table D-1 Composition of the Tissue Equivalent Matter Frequency (MHz) 900 Tissue Head Ingredients (% by weight) Bactericide 0.1 DGBE HEC 1 NaCl 1.45 Sucrose 57 Tween 20 Water 40.45 Table D-2 Recommended Tissue Dielectric Parameters (IEC 62209-1) EMC-003 (Rev.2) ONETECH Corp.: 43-14, Jinsaegol-gil, Chowol-eup, Gwangju-si, Gyeonggi-do, 12735, Korea (TEL: 82-31-799-9500, FAX: 82-31-799-9599)

oneTecH The probe is connected with a phase and ampltude stable cable to a VNA which is then calibrated with Open, Short and a Liquid with well—known parameters. All parts in the setup influencing the ampltude and phase of the signal are important and shall remain stable. Handling of the item Before usage, the active probe area has to be cleaned from any material residuals potentially contaminating the reference standards. The metal and dielectric surface must be protected to keep the precision of the criical mechanical dimensions. The connector and cable qualty are criical; any movements between calibration and measurement shall be avoided. The temperature must be stable and must not differ from the material temperature. Methods Applied and Interpretation of Parameters The calbration of the dielectric probe system is done in the steps described below for the desired frequency range and calibration package (SAR/MR!liquids, Sem—solid/solid material). Because the standard calibration in step 3 is critical for the resuls in staps 4 to 8, the sequence 3 to 8 is repeated 3 times. As a result, the result from these 3 sets is represented. 1. Configuration and mechanical / optical status. 2. Measurement resolution is 5 MHfrom 10 to 300 MHz, 50 MHz from 300 to 6000 MHz and 250 MHz from 6 to 20 GHz. 3. Standard calibration uses Air / Short / Liquid. 1 liter liquid quantity is used to reduce the influence the reflections. The liquid type is selected depending on the lowest frequency and probe diameter: DAK—1.2, DAK—3.5, Agilent OCP: de—ionized water (approx. 22 °C) DAK—12: saline solution with static conductiviy 1 S/m (approx. 22 °C) NPL OCP: pure ethanol (approx. 22 °C) 4. The cable used in the setup stays in a fixed posttion, i.e. the probe is fixed and measuring from the top in an angle of typ. 20° from the vertical axis. For DAK and Agilent probes, the refresh function (air standard) is used previous to the individual measurements in order to compensate for possible deviations from cable movements. After insertion of the probeinto a liquid, the possible air bubbles are removed from the active surface. 5.. Measurement of multiple shorts if not already available from the callbration in the previous step (NPL). Evaluation of the deviation from the previous calibration short with graphical representation of the complex quantiies and magnitude over the frequencyrange. Probe specific short is used. This assessment shows abiity to define a short circut at the end of the probe for the VNA calibration in the setup which is essential at high frequencies and depends on the probe surface qualty. 6. Measurement of validation liquids in a quantity of 1 liter at well defined temperature. Evaluation of the deviations from the target. The targets base on traceable data from reference sources. The deviation of the measurement is graphically presented for permittivity and conductivity (for lossy liquids) or loss tangent (for low losses at low frequencies) 7. Measurement of lossy liquids in a quantity of 1 Ier at well defined temperature. Head tissue simulating liquid or saline solution with 0.5 Sim static conductivity are representative. The target data base on traceable data from reference sources or from multiple measurements with precision reference probesor different evaluations such as transmission line or slotted line methods. Evaluation of the deviation from the target and graphical representation for permitivity and conductivity over the frequency range 8. Semi—solid / solld material calioration: Measurements of an elastic lossy broadband sem—solid gel with parameters close to the head tissue target. Measurements of a planar very low loss solid microwave—substrate. The average of 4 measurements of the same sample at differentlocation is shown as a single result. The deviation of the permittiity and conductivity from the reference data is evaluated. Measurements of a planarvery low loss solid microwave—substrate. The average of 4 measurements of the same sample at different location is shown as a single result. The relative deviation of the permittvity and the absolute deviation of the loss tangent is evaluated. The targets base on multiple measurements (on the same material batch at identical temperature) on convex and planar surfaces with precision reference OCP.

onetecH The measurement on sem—solid / solid materials is sensitive to the quality and planarity of the probe contact area, such as air gaps due to imperfect probes (resulting lower permitivity values). Table for the probe uncertainty: The uncertainty of the probe depending on probe type, size, material parameter range and frequencyis given in a table. It represents the best measurement capability of the specific probebut does not include the material (deviation from the target values). . Appendix with detailed results of all measurements with the uncertainties for the specific measurement. In addition to the probe uncertainty (see above), it includes the uncertainty of the reference material used for the measurement. A set of results from independent calibrations represents the capabilty of the selup and the lossymaterials used, including the precision of the measured material and the influence of temperature deviations. Temperature and operator influence was minimized and gives a good indication of the achievable repeatability of a measurement. .

Page 75 of 78 Report No. OT-19O-RWD-036 APPENDIX E: SAR SYSTEM VALIDATION Per FCC KDB Publication 865664 D02v01r02, SAR system validation status should be documented to confirm measurement accuracy. The SAR systems (including SAR probes, system components and software versions) used for 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 D01v01r04 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, using the system that normally operates with the probe for routine SAR measurements and according to the required tissue-equivalent media. A tabulated summary of the system validation status including the validation date(s), measurement frequencies, SAR probes and tissue dielectric parameters has been included.

Modulations in the table above represent test configurations for which the measurement system has been validated per FCC KDB Publication 865664 D01v01r04 for scenarios when CW probe calibrations are used with other signal types. SAR systems were validated for modulated signals with a periodic duty cycle, such as GMSK, or with a high peak to average ratio (> 5 dB), such as OFDM according to FCC KDB Publication 865664 D01v01r04.
