Phantom description The used SAM Phantom meets the requirements specified in Edition 01-01 of Supplement C to OET Bulletin 65 for Specific Absorption Rate (SAR) measurements. The phantom consists of a fibreglass shell integrated in a wooden table. It allows left-hand and right-hand head as well as body-worn measurements with a maximum liquid depth of 18 cm in head position and 22 cm in planar position (body measurements). The thickness of the Phantom shell is 2 mm +/- 0.1 mm. Report No.: WT248002349 Page 14 of 44 ELI4 Phantom Shell Thickness 2mm+/- 0.2mm Filling Volume Approximately 30 liters Measurement Areas Flat phantom The ELI4 phantom is in intended for compliance testing of handheld and body-mounted wireless devices in the frequency range of 30MHz to 6GHz. ELI4 is fully compatible with the lastest draft of the standard IEC 62209-2 and all known tissue simulating liquids. The phantom shell material is resistant to all ingredients used in the tissue-equivalent liquid recipes. The shell of the phantom including ear spacers is constructed from low permittivity and low loss material, with a relative permittivity5 and a loss tangent 0.05. 3.4. Device holder description The DASY5 device holder has two scales for device rotation (with respect to the body axis) and the device inclination (with respect to the line between the ear openings). The plane between the ear openings and the mouth tip has a rotation angle of 65°. The bottom plate contains three pair of bolts for locking the device holder. The device holder positions are adjusted to the standard measurement positions in the three sections. This device holder is used for standard mobile phones or PDA's only. If necessary an additional support of polystyrene material is used. Larger DUT's (e.g. notebooks) cannot be tested using this device holder. Instead a support of bigger polystyrene cubes and thin polystyrene plates is used to position the DUT in all relevant positions to find and measure spots with maximum SAR values. Report No.: WT248002349 Page 15 of 44 Therefore those devices are normally only tested at the flat part of the SAM. 4. SAR MEASUREMENT PROCEDURE 4.1. Scanning procedure The DASY5 installation includes predefined files with recommended procedures for measurements and system check. They are read-only document files and destined as fully defined but unmeasured masks. All test positions (head or body-worn) are tested with the same configuration of test steps differing only in the grid definition for the different test positions. The reference and drift measurements are located at the beginning and end of the batch process. They measure the field drift at one single point in the liquid over the complete procedure. The indicated drift is mainly the variation of the DUT's output power and should vary max. +/- 5 %. The surface check measurement tests the optical surface detection system of the DASY5 system by repeatedly detecting the surface with the optical and mechanical surface detector and comparing the results. The output gives the detecting heights of both systems, the difference between the two systems and the standard deviation of the detection repeatability. Air bubbles or refraction in the liquid due to separation of the sugar-water mixture gives poor repeatability (above ± 0.1mm). To prevent wrong results tests are only executed when the liquid is free of air bubbles. The difference between the optical surface detection and the actual surface depends on the probe and is specified with each probe. (It does not depend on the surface reflectivity or the probe angle to the surface within ± 30°.) The area scan measures the SAR above the DUT or verification dipole on a parallel plane to the surface. It is used to locate the approximate location of the peak SAR with 2D spline interpolation. The robot performs a stepped movement along one grid axis while the local electrical field strenth is measured by the probe. The probe is touching the surface of the SAM during acquisition of measurement values. The standard scan uses large grid spacing for faster measurement. Standard grid spacing for head measurements is 15 mm in x- and y- dimension( 2GHz)12 mm in x- and y- dimension(2-4 GHz) and 10mm in x- and y- dimension(4-6GHz). If a finer resolution is needed, the grid spacing can be reduced. Grid spacing and orientation have no Report No.: WT248002349 Page 16 of 44 influence on the SAR result. For special applications where the standard scan method does not find the peak SAR within the grid, e.g. mobile phones with flip cover, the grid can be adapted in orientation. Results of this coarse scan are shown in Appendix B. A "zoom scan" measures the field in a volume around the 2D peak SAR value acquired in the previous "coarse" scan. This is a fine grid with maximum scan spatial resolution: xzoom, yzoom 2GHZ 8 mm, 2-4GHz - 5 mm and 4-6 GHz- 4 mm; zzoom 3GHz - 5 mm, 3-4 GHz- 4 mm and 4-6GHz-2mm where the robot additionally moves the probe along the z-axis away from the bottom of the Phantom. DASY5 is also able to perform repeated zoom scans if more than 1 peak is found during area scan. Test results relevant for the specified standard (see chapter 1.5.) are shown in table form in chapter 3.2. A Z-axis scan measures the total SAR value at the x-and y-position of the maximum SAR value found during the cube scan. The probe is moved away in z-direction from the bottom of the SAM phantom in 2mm steps. This measurement shows the continuity of the liquid and can depending in the field strength- also show the liquid depth. A z-axis scan of the measurement with maximum SAR value is shown in Appendix B. The following table summarizes the area scan and zoom scan resolutions per FCC KDB 865664D01: Frequency Maximum Maximum Maximum Zoom Scan spatial resolution Minimum Area Scan resolution ( xarea, yarea) Zoom Scan spatial resolution( xzoom yzoom) Uniform Grid zzoom(n) Graded Grad zzoom(n>1) zzoom(1) zoom scan volume (x,y,z) 2GHz 15mm 8mm 5mm 4mm 5. 1.5*zzoom(n-16). 30mm 2-3GHz 12mm 5mm 5mm 4mm 30mm 1.5*zzoom(n-1) 3-4GHz 10mm 5mm 4mm 3mm 28mm 1.5*zzoom(n-1) 4-5GHz 10mm 4mm 3mm 2.5mm 25mm 1.5*zzoom(n-1) Report No.: WT248002349 Page 17 of 44 5-6GHz 10mm 4mm 2mm 2mm 22mm 1.5*zzoom(n-1) Spatial Peak SAR Evaluation The spatial peak SAR - value for 1 and 10 g is evaluated after the Cube measurements have been done. The bases of the evaluation are the SAR values measured at the points of the fine cube grid consisting of 5 x 5 x 7 points (with 8mm horizontal resolution) or 7 x 7 x 7 points (with 5mm horizontal resolution). The algorithm that finds the maximal averaged volume is separated into three different stages. The data between the dipole center of the probe and the surface of the phantom are extrapolated. This data cannot be measured since the center of the dipole is 2.7 mm away from the tip of the probe and the distance between the surface and the lowest measuring point is about 1 mm (see probe calibration sheet). The extrapolated data from a cube measurement can be visualized by selecting `Graph Evaluated'. The maximum interpolated value is searched with a straight-forward algorithm. Around this maximum the SAR - values averaged over the spatial volumes (1g or 10 g) are computed using the 3d-spline interpolation algorithm. If the volume cannot be evaluated (i.e., if a part of the grid was cut off by the boundary of the measurement area) the evaluation will be started on the corners of the bottom plane of the cube. All neighboring volumes are evaluated until no neigh boring volume with a higher average value is found. Extrapolation The extrapolation is based on a least square algorithm [W. Gander, Computermathematik, p.168-180]. Through the points in the first 3 cm along the z-axis, polynomials of order four are calculated. These polynomials are then used to evaluate the points between the surface and the probe tip. The points, calculated from the surface, have a distance of 1 mm from each other. Interpolation The interpolation of the points is done with a 3d-Spline. The 3d-Spline is composed of three one-dimensional splines with the "Not a knot"-condition [W. Gander, Computermathematik, p.141-150] (x, y and z -direction) [Numerical Recipes in C, Second Edition, p.123ff ]. Volume Averaging At First the size of the cube is calculated. Then the volume is integrated with the trapezoidal Report No.: WT248002349 Page 18 of 44 algorithm. 8000 points (20x20x20) are interpolated to calculate the average. Advanced Extrapolation DASY5 uses the advanced extrapolation option which is able to compansate boundary effects on E-field probes. 6.1.1. Data Storage and Evaluation Data Storage The DASY5 software stores the acquired data from the data acquisition electronics as raw data (in microvolt readings from the probe sensors), together with all necessary software parameters for the data evaluation (probe calibration data, liquid parameters and device frequency and modulation data) in measurement files with the extension DAE4. The software evaluates the desired unit and format for output each time the data is visualized or exported. This allows verification of the complete software setup even after the measurement and allows correction of incorrect parameter settings. For example, if a measurement has been performed with a wrong crest factor parameter in the device setup, the parameter can be corrected afterwards and the data can be re-evaluated. The measured data can be visualized or exported in different units or formats, depending on the selected probe type ([V/m], [A/m], [°C], [mW/g], [mW/cm²], [dBrel], etc.). Some of these units are not available in certain situations or show meaningless results, e.g., a SAR output in a lossless media will always be zero. Raw data can also be exported to perform the evaluation with other software packages. Data Evaluation by SEMCAD The SEMCAD software automatically executes the following procedures to calculate the field units from the microvolt readings at the probe connector. The parameters used in the evaluation are stored in the configuration modules of the software: Probe parameters: - Sensitivity - Conversion factor ConvFi - Diode compression point Dcpi Device parameters: - Frequency - Crest factor cf Media parameters: - Conductivity - Density Report No.: WT248002349 Normi, ai0, ai1, ai2 f Page 19 of 44 These parameters must be set correctly in the software. They can be found in the component documents or they can be imported into the software from the configuration files issued for the DASY5 components. In the direct measuring mode of the multimeter option, the parameters of the actual system setup are used. In the scan visualization and export modes, the parameters stored in the corresponding document files are used. The first step of the evaluation is a linearization of the filtered input signal to account for the compression characteristics of the detector diode. The compensation depends on the input signal, the diode type and the DC-transmission factor from the diode to the evaluation electronics. If the exciting field is pulsed, the crest factor of the signal must be known to correctly compensate for peak power. The formula for each channel can be given as: Vi = Ui + Ui2 cf/dcpi with Vi = compensated signal of channel i (i = x, y, z) Ui = input signal of channel i (i = x, y, z) cf = crest factor of exciting field (DASY parameter) dcpi = diode compression point (DASY parameter) From the compensated input signals the primary field data for each channel can be evaluated: E-field probes: Ei = (Vi / Normi ConvF)1/2 H-field probes: Hi = (Vi)1/2 (ai0 + ai1f + ai2f2)/f with Vi = compensated signal of channel i (i = x, y, z) Normi = sensor sensitivity of channel i (i = x, y, z) [mV/(V/m)2] for E-field Probes ConvF = sensitivity enhancement in solution aij = sensor sensitivity factors for H-field probes Report No.: WT248002349 Page 20 of 44 f = carrier frequency [GHz] Ei = electric field strength of channel i in V/m Hi = magnetic field strength of channel i in A/m The RSS value of the field components gives the total field strength (Hermitian magnitude): Etot = (Ex2 + EY2 + Ez2)1/2 The primary field data are used to calculate the derived field units.

SAR MEASUREMENT VARIABILITY AND UNCERTAINTY 9.1. SAR measurement variability Refer to section 6.2 of KDB 447498 D01: Transmitters that are built-in within a wrist watch or similar wrist-worn devices typically op erate in speaker mode for voice communication, with the device worn on the wrist and po sitioned next to the mouth. Next to the mouth exposure requires 1-g SAR and the wrist-w orn condition requires 10-g extremity SAR. The 10-g extremity and 1-g SAR test exclusio ns may be applied to the wrist and face exposure conditions. When SAR evaluation is re quired, next to the mouth use is evaluated with the front of the device positioned at 10 m m from a flat phantom filled with head tissue-equivalent medium. The wrist bands should be strapped together to represent normal use conditions. SAR for wrist exposure is evalu ated with the back of the device positioned in direct contact against a flat phantom filled with body tissue-equivalent medium. The wrist bands should be unstrapped and touching the phantom. The space introduced by the watch or wrist bands and the phantom must b e representative of actual use conditions; otherwise, if applicable, the neck or a curved h ead region of the SAM phantom may be used, provided the device positioning and SAR probe access issues have been addressed through a KDB inquiry. When other device po sitioning and SAR measurement considerations are necessary, a KDB inquiry is also req uired for the test results to be acceptable; for example, devices with rigid wrist bands or e lectronic circuitry and/or antenna(s) incorporated in the wrist bands. These test configurat ions are applicable only to devices that are worn on the wrist and cannot support other us e conditions; therefore, the operatin Report No.: WT248002349 Page 28 of 44 Per KDB865664 D01 SAR measurement 100MHz to 6GHz v01r04, SAR measurement variability must be assessed for each frequency band, which is determined by the SAR probe calibration point and tissue-equivalent medium used for the device measurements. The additional measurements are repeated after the completion of all measurement requiring the same head or body tissue-equivalent medium in a frequency band. The test device should be returned to ambient conditions (normal room temperature) with the battery fully charged before it is re-mounted on the device holder for the repeated measurement(s) to minimize any unexpected variations in the repeated results. 1) Repeated measurement is not required when the original highest measured SAR is <0.80 W/kg; step2) through 4) do not apply. 2) When the original highest measured SAR is 0.8 W/kg repeat that measurement once. 3) Perform a second repeated measurement only if the ratio of largest to smallest SAR for the original and first repeated measurements is >1.20 or when the original or repeated measurement is 1.45 W/kg(~10% from the 1-g SAR limit). 4) Perform a third repeated measurement only if the original, first or second repeated measurement is 1.5W/kg and the ratio of largest to smallest SAR for the original, first and second repeated measurements is >1.20. The same procedures should be adapted for measurements according to extremity and occupational exposure limits by applying a factor of 2.5 for extremity exposure and a Report No.: WT248002349 Page 29 of 44 factor of 5 for occupational exposure to the corresponding SAR thresholds. Report No.: WT248002349 Page 30 of 44 10. SAR MEASUREMENT VARIABILITY AND UNCERTAINTY 10.1.

The additional measurements are repeated after the completion of all measurement requiring the same head or body tissue-equivalent medium in a frequency band.

The same procedures should be adapted for measurements according to extremity and occupational exposure limits by applying a factor of 2.5 for extremity exposure and a factor of 5 for occupational exposure to the corresponding SAR thresholds. 10.2. SAR measurement uncertainty Per KDB865664 D01 SAR Measurement 100MHz to 6GHz v01r03, when the highest measured 1-g SAR within a frequency band is <1.5W/kg, the extensive SAR measurement uncertainty analysis described in IEEE Std 1528-2003 is not required in SAR reports submitted for equipment approval. The equivalent ratio(1.5/1.6) is applied to Report No.: WT248002349 Page 31 of 44 extremity and occupational exposure conditions. Report No.: WT248002349 Page 32 of 44 11.

The same procedures should be adapted for measurements according to extremity and occupational exposure limits by applying a factor of 2.5 for extremity exposure and a factor of 5 for occupational exposure to the corresponding SAR thresholds. 11.2. SAR measurement uncertainty Per KDB865664 D01 SAR Measurement 100MHz to 6GHz v01r03, when the highest measured 1-g SAR within a frequency band is <1.5W/kg, the extensive SAR measurement uncertainty analysis described in IEEE Std 1528-2003 is not required in SAR reports submitted for equipment approval. The equivalent ratio(1.5/1.6) is applied to Report No.: WT248002349 Page 33 of 44 extremity and occupational exposure conditions. 12. Test Configuration WIFI Test Configurations For WLAN SAR testing, WLAN engineering testing software installed on the DUT can provide continuous transmitting RF signal. The Tx power is set according to tune up procedure for 802.11 b mode by software. This RF signal utilized in SAR measurement has almost 100% duty cycle and its crest factor is 1. For the 802.11b/g/n SAR tests, a communication link is set up with the test mode software for WiFi mode test. During the test, at the each test frequency channel, the EUT is operated at the RF continuous emission mode. Report No.: WT248002349 Page 34 of 44 13. AR TEST RESULTS 13.1. EUT Antenna Locations Report No.: WT248002349 Page 35 of 44 14. MEASUREMENT RESULTS Result: Passed Date of testing : Ambient temperature : Relative humidity : 14.1. SAR measurement Results 2025.01.06~2025.01.06 20~22 50~68% General Notes: 1) Per KDB447498 D01v06, all measurement SAR results are scaled to the maximum tune-up tolerance limit to demonstrate compliant. 2) Per KDB447498 D01v06, testing of other required channels within the operating mode of a frequency band is not required when the reported 1-g or 10-g SAR for the mid-band or highest output power channel is :0.8 W/kg or 2.0W/kg, for 1-g or 10-g respectively, when the transmission band is 100MHz. When the maximum output power variation across the required test channels is >1/2 dB, instead of the middle channel, the highest output power channel must be used. 3) Per KDB865664 D01v01r04, for each frequency band, repeated SAR measurement is required only when the measure SAR is 0.8W/kg; if the deviation among the repeated measurement is 20%, and the measured SAR<1.45W/kg, only one repeated measurement is required. 4) Per KDB 941225 D06 Hotspot Mode SAR v02:r01, the DUT dimension is bigger than 9cm*5cm, so 10mm is chosen as the test separation distance for Hotspot mode. When the antenna-to-edge distance is greater than 2.5cm, such position does not need to be tested. 5) Per KDB648474 D04v01r03, SAR is evaluated without a headset connected to the device. When the standalone reported body-worn SAR is 1.2W/kg, no additional SAR evaluations using a headset are required. 6) Per KDB865664 D02v01r02, SAR plot is only required for the highest measured SAR in each exposure configuration, wireless mode and frequency band combination; plots are also required when the measured SAR is >1.5W/kg, or >7.0W/kg for occupational exposure. The published RF exposure KDB procedures may require additional plots; for Report No.: WT248002349 Page 36 of 44 example, to support SAR to peak location separation ratio test exclusion and/or volume scan plots-processing (refer to appendix B for details). WLAN Notes Per KDB 248227 D01v02r02, for all positions/configurations tested using the initial test position and subsequent test positions, when the reported SAR is > 0.8 W/kg, SAR is measured for these test positions/configurations on the subsequent next highest measured output power channel(s) until the reported SAR is 1.2 W/kg or all required channels are tested. Per KDB 248227 D01v02r02, for 802.11g/n SAR testing is required. When the highest reported SAR for DSSS is adjusted by the ratio of OFDM to DSSS specified maximum output power and the adjusted SAR is > 1.2 W/kg. Per KDB 248227 D01v02r02, for OFDM transmission configurations in the 2.4 GHz bands, When the same maximum power is specified for multiple transmission modes in a frequency band, the largest channel bandwidth, lowest order modulation, lowest data rate and lowest order 802.11g/n mode is used for SAR measurement, on the highest measured output power channel for each frequency band.

Repeated SAR results Remark: 1. Per KDB 865664 D01v01r04, for each frequency band, repeated SAR measurement is required only when the measured SAR is 0.8W/kg. 2. Per KDB 865664 D01v01r04, if the ratio among the repeated measurement is 1.2 and the measured SAR<1.45W/kg, only one repeated measurement is required. 3. The ratio is the difference in percentage between original and repeated measured SAR. 4. All measurement SAR result is scaled-up to account for tune-up tolerance and is compliant.
