                               i.e., 8 = 0 is normal to probe axis

 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 Wireiless 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:
           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).
           NORM(Px,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: DGP 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, 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 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.
            Sensor Offset: The sensor offset corresponds to the offset of virtual measurement center from the probe tip
            {on probe axis). No tolerance 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 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.
