NORMx,y,z are only intermediate values, i.e., the uncertainties of NORMx,y,z does not effect the 2 E -field uncertainty inside TSL (see below ConvF). • NORM(f)x,y,z = NORMx,y,z* frequency_response (see Frequency Response Chart). This linearization is implemented in DASY4 software versions later than 4.2. The uncertainty of the frequency response is included in the stated uncertainty of ConvF. • DCPx,y,z: DCP are numerical linearization parameters assessed based on the data of power sweep (no uncertainty required) . DCP does not depend on frequency nor media. • PAR: PAR is the Peak to Average Ratio that is not calibrated but determined based on the signal characteristics . • Ax, y,z; Bx,y,z; Cx, y,z;VRx,y,z:A,B,C are numerical linearization parameters assessed based on the data of power sweep for specific modulation signal. The parameters do not depend on frequency nor media. VR is the maximum calibration range expressed in RMS voltage across the diode. • ConvF and Boundary Effect Parameters: Assessed in flat phantom using E-field (or Temperature Transfer Standard for fS800MHz) and inside waveguide using analytical field distributions based on power measurements for f >800MHz. The same setups are used for assessment of the parameters applied for boundary compensation (alpha, depth) of wh ich typical uncertainty valued are given. These parameters are used in DASY4 software to improve probe accuracy close to the boundary. The sensitivity in TSL corresponds to NORMx,y,z* ConvF whereby the uncertainty corresponds to that given for ConvF. A frequency dependent ConvF is used in DASY version 4.4 and higher which allows extending the validity from±50MHz to±100MHz. • Spherical isotropy (30 deviation from isotropy): in a field of low gradients realized using a flat phantom exposed by a patch antenna. • Sensor Offset: The sensor offset corresponds to the offset of virtual measurement center from the probe tip (on probe axis). No tolerance required . • Connector Angle: The angle is assessed using the information gained by determining the NORMx (no uncertainty required). Certificate No: Z 18-60553 Page 2 of 11

Calibration Laboratory of Schmid & Partner s Schweizerischer Kalibrierdienst Service suisse d'etalonnage Engineering AG C Servizio svizzero di taratura Zeughausstrasse 43, 8004 Zurich, Switzerland s Swiss Calibration Service Accredited by the Swiss Accreditation Service (SAS} Accreditation No.: SCS 0108 The Swiss Accreditation Service is one of the signatories to the EA Multilateral Agreement for the recognition of calibration certificates Glossary: TSL tissue simulating liquid NORMx,y,z sensitivity in free space ConvF sensitivity in TSL / NORMx,y,z DCP diode compression point CF crest factor (1 /duty_cycle) of the RF signal A,B,C, D modulation dependent linearization parameters Polarization <p <p rotation around probe axis Polarization S S rotation around an axis that is in the plane normal to probe axis (at measurement center), i.e., S = 0 is normal to probe axis Connector Angle information used in DASY system to align probe sensor X to the robot coordinate system Calibration is Performed According to the Following Standards: a) IEEE Std 1528-2013, "IEEE Recommended Practice for Determining the Peak Spatial-Averaged Specific Absorption Rate (SAR) in the Human Head from Wireless Communications Devices: Measurement Techniques", June 2013 b) IEC 62209-1, ", "Measurement procedure for the assessment of Specific Absorption Rate (SAR) from hand- held and body-mounted devices used next to the ear (frequency range of 300 MHz to 6 GHz)", July 2016 c) IEC 62209-2, "Procedure to determine the Specific Absorption Rate (SAR) for wireless communication devices used in close proximity to the human body (frequency range of 30 MHz to 6 GHz)", March 2010 d) KDB 865664, "SAR Measurement Requirements for 100 MHz to 6 GHz" Methods Applied and Interpretation of Parameters: • NORMx,y,z: Assessed for E-field polarization S = 0 (f ~ 900 MHz in TEM-cell; f > 1800 MHz: R22 waveguide). NORMx,y,z are only intermediate values, i.e., the uncertainties of NORMx,y,z does not affect the E 2-field uncertainty inside TSL (see below ConvF). • NORM(f)x,y,z = NORMx,y,z * frequency_response (see Frequency Response Chart). This linearization is implemented in DASY4 software versions later than 4.2. The uncertainty of the frequency response is included in the stated uncertainty of ConvF. • DCPx,y,z: DCP are numerical linearization parameters assessed based on the data of power sweep with CW signal (no uncertainty required). DCP does not depend on frequency nor media. • PAR: PAR is the Peak to Average Ratio that is not calibrated but determined based on the signal characteristics • Ax,y ,z; Bx,y,z; Cx,y,z; Dx,y,z; VRx,y,z: A, 8 , C, Dare numerical linearization parameters assessed based on the data of power sweep for specific modulation signal. The parameters do not depend on frequency nor media. VR is the maximum calibration range expressed in RMS voltage across the diode. • ConvF and Boundary Effect Parameters: Assessed in flat phantom using E-field (or Temperature Transfer Standard for f ~ 800 MHz) and inside waveguide using analytical field distributions based on power measurements for f > 800 MHz. The same setups are used for assessment of the parameters applied for boundary compensation (alpha, depth) of which typical uncertainty values are given. These parameters are used in DASY4 software to improve probe accuracy close to the boundary. The sensitivity in TSL corresponds to NORMx,y,z * ConvF whereby the uncertainty corresponds to that given for ConvF. A frequency dependent ConvF is used in DASY version 4.4 and higher which allows extending the validity from± 50 MHz to± 100 MHz. • Spherical isotropy (30 deviation from isotropy) : in a field of low gradients realized using a flat phantom exposed by a patch antenna. • Sensor Offset: The sensor offset corresponds to the offset of virtual measurement center from the probe tip (on probe axis). No tolerance required. • Connector Angle: The angle is assessed using the information gained by determining the NORMx (no uncertainty required). Certificate No: EX3-7306_Jul1 8 Page 2 of 11
