Methods Applied and Interpretation of Parameters:
      »   Measurement Conditions: Further details are available from the Validation Report at the end
          of the certificate. All figures stated in the certificate are valid at the frequency indicated.
      *   Antenna Parameters with TSL: The dipole is mounted with the spacer to position its feed
          point exactly below the center marking of the flat phantom section, with the arms oriented
          paralie! to the body axis.
      e   Feed Point Impedance and Return Loss: These parameters are measured with the dipole
          positioned under the liquid filled phantom. The impedance stated is transformed from the
          measurement at the SMA connector to the feed point. The Return Loss ensures low
          reflected pawer, No uncertainty required.
      *   Electrical Delay: One—way delay between the SMA connector and the antenna feed point.
          No uncertainty required.
      *   SAR measured: SAR measured at the stated antenna input power.
      *   SAR normalized: SAR as measured, normalized to an input power of 1 W at the antenna
          connector.
      &   SAR for nominal TSL parameters; The measured TSL parameters are used to calculate the
          nominal SAR result.
  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%.                                                       :

General Antenna Parameters and Design

      Electrical Delay (one direction)                                                  1.152 ns

After long term use with 100W radiated power, only a slight warming of the dipole near the feedpoint can be measured.

The dipole is made of standard semirigid coaxial cable. The center conductor of the feeding line is directly connected to the
second arm of the dipole. The antenna is therefore short—circuited for DC—signals. On some of the dipoles, small end caps
are added to the dipole arms in order to improve matching when loaded according to the position as explained in the
"Measurement Conditions" paragraph. The SAR data are not affected by this change. The overall dipole length is still
according to the Standard.
No excessive force must be applied to the dipole arms, because they might bend or the soldered connections near the
feedpoint may be damaged.

filter were connected to a calibrated source (e. a signal generator) to determine the losses of the measurement path.

                               Per KDB 865664 D01, calibration intervals of up to three years may be considered for reference dipoles
                               when it is demonstrated that the SAR target, impedance and return loss of a dipole have remained
                               stable according to the following requirements:

                                   1. The measured SAR does not deviate more than 10% from the target on the calibration
                                       certificate.
                                   2. The return-loss does not deviate more than 20% from the previous measurement and meets the
                                       required 20dB minimum return-loss requirement.
                                   3. The measurement of real or imaginary parts of impedance does not deviate more than 5Ω from
                                       the previous measurement.
                               The following dipole was checked to pass the above 3 requirements to have 2-year calibration period
                               from the calibration date:

APPENDIX D: SAR TISSUE SPECIFICATIONS

Measurement Procedure for Tissue verification:
                  1) The network analyzer and probe system was configured and calibrated.
                  2) The probe was immersed in the tissue. The tissue was placed in a nonmetallic container.
                     Trapped air bubbles beneath the flange were minimized by placing the probe at a slight angle.
                  3) The complex admittance with respect to the probe aperture was measured
                  4) The complex relative permittivity ε’ can be calculated from the below equation (Pournaropoulos
                     and Misra):
                         j 2ωε r ε 0                 b     b   π                       [

APPENDIX E: SAR SYSTEM VALIDATION

Per FCC KDB Publication 865664 D02v01r02, SAR system validation status should be documented to confirm
measurement accuracy. The SAR systems (including SAR probes, system components and software versions)
used for this device were validated against its performance specifications prior to the SAR measurements.
Reference dipoles were used with the required tissue- equivalent media for system validation, according to the
procedures outlined in FCC KDB Publication 865664 D01v01r04 and IEEE 1528-2013. Since SAR probe
calibrations are frequency dependent, each probe calibration point was validated at a frequency within the valid
frequency range of the probe calibration point, using the system that normally operates with the probe for routine
SAR measurements and according to the required tissue-equivalent media.

A tabulated summary of the system validation status including the validation date(s), measurement frequencies,
SAR probes and tissue dielectric parameters has been included.

                                                                    Table E-1

NOTE: While the probes have been calibrated for both CW and modulated signals, all measurements were
performed using communication systems calibrated for CW signals only. Modulations in the table above represent
test configurations for which the measurement system has been validated per FCC KDB Publication 865664
D01v01r04 for scenarios when CW probe calibrations are used with other signal types. SAR systems were
validated for modulated signals with a periodic duty cycle, such as GMSK, or with a high peak to average ratio (>5
dB), such as OFDM according to FCC KDB Publication 865664 D01v01r04.
