System Verification 9.1 Tissue Verification The dielectric properties for this Tissue Simulant Liquids were measured by using the SPEAG Model DAK3.5 Dielectric Probe in conjunction with Agilent E5071B Network Analyzer (300 kHz – 8 500 MHz). The Conductivity (σ) and Permittivity (ρ) are listed in Table 1.For the SAR measurement given in this report. The temperature variation of the Tissue Simulant Liquids was (22 ± 2) °C. Freq. Tissue Temp Limit/Measured Permittivity (ρ) Conductivity (σ) (MHz) Type (℃) 52.70 ± 5 % 1.95 ± 5 % Recommended Limit 22 ± 2 2 450 MSL (50.07 ~ 55.34) (1.85 ~ 2.05) Measured, 2019-03-25 52.52 2.00 20.56 <Table 1.Measurement result of Tissue electric parameters> This test report shall not be reproduced, except in full, without the written approval KCTL-TIA002-004/1

The daily system accuracy verification occurs within the flat section of the SAM phant om. A SAR measurement was performed to see if the measured SAR was within ± 1 0% from the target SAR values. The tests were conducted on the same days as the measurement of the EUT. The obtained results from the system accuracy verification are displayed in the Table 2. During the tests, the ambient temperature of the laboratory was in the range (22 ± 2) ℃, the relative humidity was in the range(50 ± 20)% and the liquid depth Above the ear/grid reference points was above 15 cm in all the cases. It is seen that the system is operating within its specification, as the re sults are within acceptable tolerance of the reference values. Validation Dipole Ant.

SAR Measurement Procedures Step 1: Power Reference Measurement The Power Reference Measurement and Power Drift Measurements are for monitoring the power drift of the device under test in the batch process. The Minimum distance of probe sensors to surface determines the closest measurement point to phantom surface. The minimum distance of probe sensors to surface is 2 mm. This distance cannot be smaller than the Distance of sensor calibration points to probe tip as defined in the probe properties. Step 2: Area Scan The Area Scan is used as a fast scan in two dimensions to find the area of high field values, before doing a fine measurement around the hot spot. The sophisticated interpolation routines implemented in DASY software can find the maximum locations even in relatively coarse grids. When an Area Scan has measured all reachable points, it computes the field maximal found in the scanned area, within a range of the global maximum. The range (in dB) is specified in the standards for compliance testing. For example, a 2 dB range is required in IEEE Standard 1528 and IEC 62209 standards, whereby 3 dB is a requirement when compliance is assessed in accordance with the ARIB standard (Japan). If only one Zoom Scan follows the Area Scan, then only the absolute maximum will be taken as reference. For cases where multiple maximums are detected, the number of Zoom Scans has to be increased accordingly. Area Scan Parameters extracted from KDB 865664 D01 SAR Measurement 100 MHz to 6 GHz v01r04.

The Zoom Scan measures 5x5x7 points within a cube whose base faces are centered on the maxima found in a preceding area scan job within the same procedure. When the measurement is done, the Zoom Scan evaluates the averaged SAR for 1 g and 10 g and displays these values next to the job’s label. Zoom Scan Parameters extracted from KDB 865664 D01 SAR Measurement 100 MHz to 6 GHz v01r04. ≤ 3 GHz > 3 GHz Maximum distance from closest measurement point (geometric center of probe sensors) to phantom surface 5 mm ± 1 mm ½ ·δ·ln(2) mm 0.5 mm Maximum probe angle from probe axis to phantom surface normal at the measurement location 30° ± 1° 20° ± 1° ≤ 2 GHz: ≤ 15 mm 3 – 4 GHz: ≤ 12 mm 2 – 3 GHz: ≤ 12 mm 4 – 6 GHz: ≤ 10 mm When the x or y dimension of the test device, in the Maximum area scan spatial resolution: ΔxArea, ΔyArea measurement plane orientation, is smaller than the above, the measurement resolution must be ≤ the corresponding x or y dimension of the test device with at least one measurement point on the test device. ≤ 2 GHz: ≤ 8 mm 3 – 4 GHz: ≤ 5 mm* Maximum zoom scan spatial resolution: ΔxZoom, ΔyZoom 2 – 3 GHz: ≤ 5 mm* 4 – 6 GHz: ≤ 4 mm* 3 – 4 GHz: ≤ 4 mm uniform grid: ΔzZoom(n) ≤ 5 mm 4 – 5 GHz: ≤ 3 mm 5 – 6 GHz: ≤ 2 mm Maximum zoom ΔzZoom(1): between 3 – 4 GHz: ≤ 3 mm scan spatial 1st two points closest ≤ 4 mm 4 – 5 GHz: ≤ 2.5 mm resolution, normal to graded to phantom surface 5 – 6 GHz: ≤ 2 mm phantom surface grid ΔzZoom(n>1): between subsequent ≤ 1.5·ΔzZoom(n-1) mm points 3 – 4 GHz: ≥ 28 mm Minimum zoom x, y, z ≥ 30 mm 4 – 5 GHz: ≥ 25 mm scan volume 5 – 6 GHz: ≥ 22 mm Note: δ is the penetration depth of a plane-wave at normal incidence to the tissue medium; see IEEE Std 1528-2013 for details. * When zoom scan is required and the reported SAR from the area scan based 1-g SAR estimation procedures of KDB Publication 447498 is ≤ 1.4 W/kg, ≤ 8 mm, ≤ 7 mm and ≤ 5 mm zoom scan resolution may be applied, respectively, for 2 GHz to 3 GHz, 3 GHz to 4 GHz and 4 GHz to 6 GHz. Step 4: Power drift measurement The Power Drift Measurement measures the field at the same location as the most recent power reference measurement within the same procedure, and with the same settings. The Power Drift Measurement gives the field difference in dB from the reading conducted within the last Power Reference Measurement. This allows a user to monitor the power drift of the device under test within a batch process. The measurement procedure is the same as Step 1. Step 5: Z-Scan The Z Scan measures points along a vertical straight line. The line runs along the Z-axis of a one dimensional grid. In order to get a reasonable extrapolation, the extrapolated distance should not be larger than the step size in Z-direction. * Z Scan Report on Liquid Measure the height Appendix C.

SAR Test Results KDB 447498 D01, General RF Exposure Guidance Testing of other required channels within the operating mode of a frequency band is not required when the reported SAR for the mid-band or highest output power channel is: (1) ≤ 0.8 W/kg or 2.0 W/kg, for 1-g or 10-g respectively, when the transmission band is ≤ 100 MHz (2) ≤ 0.6 W/kg or 1.5 W/kg, for 1-g or 10-g respectively, when the transmission band is between 100 MHz and 200 MHz (3) ≤ 0.4 W/kg or 1.0 W/kg, for 1-g or 10-g respectively, when the transmission band is ≥ 200 MHz SAR values were scaled to the maximum allowed power to determine compliance per KDB Publication 447498 D01v06. KDB 248227 D01 SAR meas for 802.11: DSSS and OFDM configurations are considered separately according to the required SAR procedures. SAR is measured in the initial test position using the 802.11 transmission mode configuration required by the DSSS procedure or initial test configuration and subsequent test configuration(s) according to the OFDM procedures. The initial test position procedure is described in the following: ● ≤ 0.4 W/kg, further SAR measurement is not required for the other test positions in that exposure configuration and wireless mode combination within the frequency band or aggregated band. DSSS and OFDM configurations are considered separately according to the required SAR procedures. ● > 0.4 W/kg, SAR is repeated using the same wireless mode test configuration tested in the initial test position to measure the subsequent next closet/smallest test separation distance and maximum coupling test position, on the highest maximum output power channel, until the reported SAR is ≤ 0.8 W/kg or all required test positions are tested. □ For subsequent test positions with equivalent test separation distance or when exposure is dominated by coupling conditions, the position for maximum coupling condition should be tested. □ When it is unclear, all equivalent conditions must be tested. ● For all positions/configurations tested using the initial test position and subsequent test positions, when the reported SAR is > 0.8 W/kg, measure the SAR for these positions/configurations on the subsequent next highest measured output power channel(s) until the reported SAR is ≤ 1.2 W/kg or all required test channels are considered. □ The additional power measurements required for this step should be limited to those necessary for identifying subsequent highest output power channels to apply the test reduction.

This device contains transmitters that may operate simultaneously. Therefore simultaneous transmission analysis is required. Per FCC KDB 447498 D01v06, simultaneous transmission SAR test exclusion may be applied when the sum of the 1-g SAR for all the simultaneous transmitting antennas in a specific a physical test configuration is ≤ 1.6W/kg. When standalone SAR is not required to be measured per FCC KDB 447498 D01v06, the following equation must be used to estimate the standalone 1-g SAR for simultaneous transmission assessment involving that transmitter. √𝑓 (𝐺𝐻𝑧) (𝑀𝑎𝑥 𝑃𝑜𝑤𝑒𝑟 𝑜𝑓 𝐶ℎ𝑎𝑛𝑛𝑒𝑙 𝑚𝑊) 𝐸𝑠𝑡𝑖𝑚𝑎𝑡𝑒𝑑 𝑆𝐴𝑅 = ∗ 7.5 𝑀𝑖𝑛 𝑆𝑒𝑝𝑎𝑟𝑎𝑡𝑖𝑜𝑛 𝐷𝑖𝑠𝑡𝑎𝑛𝑐𝑒 Maximum Separation Estimated SAR Frequency Mode Allowed Power Distance (Body) (Body) (MHz) (mW) (mm) (W/kg) Bluetooth 2 480 3.98 5 0.167 This test report shall not be reproduced, except in full, without the written approval KCTL-TIA002-004/1

When the sum of 1-g or 10-g SAR of all simultaneously transmitting antennas in an operating mode and exposure condition combination is within the SAR limit, SAR test exclusion applies to that simultaneous transmission configuration. Per KDB Publication 447498 D01v06. * The above numerical summed SAR results for all the worst-case simultaneous transmission conditions were below the SAR limit (1.6 W/kg per 1-g). Therefore, the above analysis is sufficient to determine that simultaneous transmission cases will not exceed the SAR limit. And therefore no measured volumetric simultaneous SAR summation is required per FCC KDB Publication 447498 D01v06. .
