7.0 EVALUATION PROCEDURES

The Specific Absorption Rate (SAR) evaluation was performed in the following manner:

a. (i) The evaluation was performed in an applicable area of the phantom depending on the type
of device being tested. For devices worn about the ear during normal operation, both the left and
right ear positions were evaluated at the center frequency of the band at maximum power. The
side, which produced the greatest SAR, determined which side of the phantom would be used for
the entire evaluation. The positioning of the head worn device relative to the phantom was
dictated by FCC OET bulletin 65 Supp., C.
(ii) For body worn devices or devices which can be operated within 20 cm of the body, the
planar section of the phantom was used. The type of device being evaluated dictated the distance
of the EUT to the outer surface of the planar phantom.

b. The SAR was determined by a pre-defined procedure within the DASY3 software. Upon
completion of a reference and optical surface check, the exposed region of the phantom was
scanned near the inner surface with a grid spacing of 20mm x 20mm.

c. A 5x5x7 matrix was performed around the greatest spatial SAR distribution found during the
area scan of the applicable exposed region. SAR values were then calculated using a 3-D spline
interpolation algorithm and averaged over spatial volumes of 1 and 10 grams.

d. If the EUT had any appreciable drift over the course of the evaluation, then the EUT was re-
evaluated. Any unusual anomalies over the course of the test also warranted a re-evaluation.

8.0 SYSTEM VALIDATION

Prior to the assessment, the system was verified in the planar region of the phantom. For devices
operating below 1GHz, an 835MHz dipole or 900MHz was used, depending on the operating
frequency of the EUT. For devices operating above 1GHz, an 1800MHz dipole was used. A
forward power of 250mW was applied to the dipole and system was verified to a tolerance of
+5%. Following the validation, the fluid remained or was changed depending on the particular
part of the body being evaluated. The applicable verification(s) is/are as follows (see Appendix
B for validation test plot):

9.0 SIMULATED TISSUES

The brain and muscle mixtures consist of a viscous gel using hydroxethylcellullose (HEC)
gelling agent and saline solution. Preservation with a bactericide was added and visual
inspection was made to ensure air bubbles are not trapped during the mixing process. The
mixture was calibrated to obtain proper dielectric constant (permittivity) and conductivity of
the tissue.

10.0 TISSUE PARAMETERS

The dielectric parameters of the fluids were verified prior to the SAR evaluation using an
85070C Dielectric Probe Kit and an 8753E Network Analyzer. The dielectric parameters of the
fluid are as follows:

Measurement uncertainties in SAR measurements are difficult to quantify due to several
variables including biological, physiological, and environmental. However, the estimated
measurement uncertainties in SAR are less than 15-25 %.

According to ANSI/IEEE C95.3, the overall uncertainties are difficult to assess and will vary
with the type of meter and usage situation. However, accuracy’s of ± 1 to 3 dB can be expected
in practice, with greater uncertainties in near-field situations and at higher frequencies (shorter
wavelengths), or areas where large reflecting objects are present. Under optimum measurement
conditions, SAR measurement uncertainties of at least ± 2dB can be expected.

According to CENELEC, typical worst-case uncertainty of field measurements is ± 5 dB.
For well-defined modulation characteristics the uncertainty can be reduced to ± 3 dB.
