Calibration is Performed According to the Following Standards:
    a)   IEEE Std 1528—2003, "IEEE Recommended Practice for Determining the Peak Spatial—Averaged Specific
         Absorption Rate (SAR) in the Human Head from Wireless Communications Devices: Measurement
         Techniques", December 2003
    b)   IEC 62209—1, "Procedure to measure the Specific Absorption Rate (SAR) for hand—held devices used in close
         proximity to the ear (frequency range of 300 MHz to 3 GHz)", February 2005

Methods Applied and Interpretation of Parameters:
    e    NORMx,y,z: Assessed for E—field polarization 8 = 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—field
         uncertainty inside TSL (see below ConvF).
    e    NORM(Mx,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.
    e    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
    e    Axy,zi Bxy.z Cxy,z; Dxy.z; VRxy,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 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 (3D deviation from isotropy): in a field of low gradients realized using a flat phantom
         exposed by a patch antenna.
    e    Sensor Offset: The sensoroffset corresponds to the offset of virtual measurement center from the probe tip
         (on probe axis). No tolerance required.

 The reported uncertainty of measurementis 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 NormX,Y,Z do not affect the E—field uncertainty inside TSL (see Pages 5 and 6).
° Numerical linearization parameter: uncertainty not required.
& Uncertainty is determined using the max. deviation from linear response applying rectangular distribution and is expressed for the square of the
field value.

© Frequency validity 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 ConvF uncertainty atcalibration frequency and the uncertainty for the indicated frequency band.
" At frequencies below 3 GHz, the validity of tissue parameters (c and &) can be relaxed to + 10% if liquid compensation formula is applied to
measured SAR values. At frequencies above 3 GHz, the validity of tissue parameters (s and a) is restricted to + 5%. The uncertainty is the RSS of
the ConvF uncertainty for indicated target tissue parameters.
