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
      5)   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
      0)   IEC 62209—2, "Procedureto 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,2: Assessed for E—field polarization 9 = 0 (f < 900 MHz in TEM—cell; £ > 1800 MHz: R22 waveguide).
           NORMx,y.z are only intermediate values, ie., the uncertainties of NORMx,y,z does not affect the E*—feld
           uncertainty inside TSL (see below ConvF).
           NORM(Axy,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 numericallinearization 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
           Auy.e Bxya Coye Dxy,z; VRuy.z: A, B, C, D 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 calbration range expressed in RMS voitage across the diode.
           ConvF and Boundary Effect Parameters:Assessed in flat phantom using E—field {or Temperature Transfer
           Standard for f s 800 MHz) and inside waveguide using analytical field distributions based on power
           measurements forf > 800 MHz. The same setups are used for assessmentof 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 x 100
           MHz.
           Spherical isotropy (3D deviation from isotropy): in a field of low gradients realized using a fiat 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 determiningthe NORMx (no
           uncertainty required).

 The reported uncertainty of measurement is stated as the standard uncertainty of measurement
 multiplied by the coverage factor k=2, which for a normal distribution corresponds to a coverage
 probability of approximately 95%.


* The uncertainties of Norm X,Y,Z do not affect the E*—feld uncertainty inside TL (see Pages 5 and 6).
* Numerical Inearization paremeter: uncertainty not required
* Uncerfainty is determined using the max. deviation from linear response applying rectanguler distribution and is expressed for the square of the
field velue.

® Frequency valtity above 300 MHz of + 100 MHz only applies for DASY v4.4 and higher (see Page 2). else it is restricted to + 50 MHz. The
uncertainty is the RSS of the Convuncertainty at callbration frequency and the uncertainty for the indicated frequency band. Frequency validty
below 800 Mz is + 10, 25, 40, 50 and 70 MHz for ConvF assessments at 30, 64, 128, 150 and 220 Mz respectvely. Above 5 GHz frequency
valldty can be extended to k 110 MHz
" Atfrequencies below 3 GHz, the validity of fissue parameters (s and e) can be relaxed to + 10% if iquid compensation formula is applied to
measured SAR values. At frequencies above 3 GHz, the validty of lissue parameters (e and o) is restricted to + 5%. The uncertainty s the RSS of
the ConvF uncertainty for indicated target tissue parameters
* Alpha/Depth are determined during calibration. SPEAG warrants that the remaining deviation due to the boundary effect after compensation is
always less than & 1% for frequencies below 3 GHz and below # 2% for requencies between 3—6 GHz at any distance larger than half the probetip
diameterfrom the boundary.
