    as described in this report.
     Battery:            7.2V Lithium-Ion (P/N: 318-013-001)
2. REQUIREMENTS FOR COMPLIANCE TESTING DEFINED BY THE FCC
     The US Federal Communications Commission has released the report and order
     “Guidelines for Evaluating the Environmental Effects of RF Radiation", ET Docket No. 93-62
     in August 1996 [1]. The order requires routine SAR evaluation prior to equipment
     authorization of portable transmitter devices, including portable telephones. For consumer
     products, the applicable limit is 1.6 mW/g for an uncontrolled environment and 8.0 mW/g for
     an occupational/controlled environment as recommended by the ANSI/IEEE standard
     C95.1-1992 [6]. According to the Supplement C of OET Bulletin 65 “Evaluating Compliance
     with FCC Guide-lines for Human Exposure to Radio frequency Electromagnetic Fields",
     released on Jun 29, 2001 by the FCC, the device should be evaluated at maximum output
     power (radiated from the antenna) under “worst-case” conditions for normal or intended use,
     incorporating normal antenna operating positions, device peak performance frequencies
     and positions for maximum RF energy coupling.
3. DOSIMETRIC ASSESSMENT SYSTEM
     These measurements were performed with the automated near-field scanning system
     DASY4 from Schmid & Partner Engineering AG (SPEAG). The system is based on a high
     precision robot (working range greater than 0.9 m) which positions the probes with a
     positional repeatability of better than ± 0.02 mm. Special E- and H-field probes have been
     developed for measurements close to material discontinuity, the sensors of which are
     directly loaded with a Schottky diode and connected via highly resistive lines to the data
     acquisition unit. The SAR measurements were conducted with the dosimetric probe
     ES3DV2-SN: 3021 (manufactured by SPEAG), designed in the classical triangular
     configuration and optimized for dosimetric evaluation. The probe has been calibrated
     according to the procedure with accuracy of better than ±10%. The spherical isotropy was
     evaluated with the procedure and found to be better than ±0.25 dB. The phantom used was
     the SAM Twin Phantom as described in FCC supplement C, IEEE P1528 and EN50361.

                and software. An arm extension for accommodating the data acquisition electronics (DAE).
           •    A dosimetric probe, i.e., an isotropic E-field probe optimized and calibrated for usage in
                tissue simulating liquid. The probe is equipped with an optical surface detector system.
           •    A data acquisition electronics (DAE) which performs the signal amplification, signal
                multiplexing, AD-conversion, offset measurements, mechanical surface detection, collision
                detection, etc. The unit is battery powered with standard or rechargeable batteries. The
                signal is optically transmitted to the EOC.
           •    The Electro-optical converter (EOC) performs the conversion between optical and electrical
                of the signals for the digital communication to the DAE and for the analog signal from the
                optical surface detection. The EOC is connected to the measurement server.
           •    The function of the measurement server is to perform the time critical tasks such as signal
                filtering, control of the robot operation and fast movement interrupts.
           •    A probe alignment unit which improves the (absolute) accuracy of the probe positioning.
           •    A computer operating Windows 2000 or Windows XP.
           •    DASY4 software.
           •    Remote control with teach pendant and additional circuitry for robot safety such as warning
                lamps, etc.
           •    The SAM twin phantom enabling testing left-hand and right-hand usage.
           •    The device holder for handheld mobile phones.
           •    Tissue simulating liquid mixed according to the given recipes.
           •    Validation dipole kits allowing validating the proper functioning of the system.

REPORT NO: 04U2716-1B                              DATE: May 26, 2004                                 FCC ID: HN2SB555-2



     3.2. SYSTEM COMPONENTS
     DASY4 MEASUREMENT SERVER
                                          The DASY4 measurement server is based on a PC/104 CPU
                                          board with a 166MHz low-power Pentium, 32MB chip disk and
                                          64MB RAM. The necessary circuits for communication with
                                          either the DAE3 electronic box as well as the 16-bit AD-converter
                                          system for optical detection and digital I/O interface are contained
                                          on the DASY4 I/O-board, which is directly connected to the
                                          PC/104 bus of the CPU board.
                                          The measurement server performs all real-time data evaluation
     for field measurements and surface detection, controls robot movements and handles safety
     operation. The PC-operating system cannot interfere with these time critical processes. All
     connections are supervised by a watchdog, and disconnection of any of the cables to the
     measurement server will automatically disarm the robot and disable all program-controlled robot
     movements. Furthermore, the measurement server is equipped with two expansion slots which are
     reserved for future applications. Please note that the expansion slots do not have a standardized
     pinout and therefore only the expansion cards provided by SPEAG can be inserted. Expansion cards
     from any other supplier could seriously damage the measurement server. Calibration: No calibration
     required.
     DATA ACQUISITION ELECTRONICS (DAE)
     The data acquisition electronics (DAE3) consists of a highly sensitive
     electrometer grade preamplifier with auto-zeroing, a channel and gain-switching
     multiplexer, a fast 16 bit AD converter and a command decoder and control logic
     unit. Transmission to the measurement server is accomplished through an
     optical downlink for data and status information as well as an optical uplink for
     commands and the clock. The mechanical probe mounting device includes two
     different sensor systems for frontal and sideways probe contacts. They are used for mechanical
     surface detection and probe collision detection. The input impedance of the DAE3 box is 200MOhm;
     the inputs are symmetrical and floating. Common mode rejection is above 80 dB.

4. EVALUATION PROCEDURES

     DATA EVALUATION
The DASY4 post processing software (SEMCAD) automatically executes the following procedures to
calculate the field units from the microvolt readings at the probe connector. The parameters used in the
evaluation are stored in the configuration modules of the software:
            Probe parameters: - Sensitivity                         Normi, ai0, ai1, ai2
                                   - Conversion factor              ConvFi
                                   - Diode compression point dcpi
            Device parameters: - Frequency                          f
                                   - Crest factor                   cf
            Media parameters: - Conductivity                        σ
                                   - Density                        ρ
These parameters must be set correctly in the software. They can be found in the component documents
or be imported into the software from the configuration files issued for the DASY components. In the
direct measuring mode of the multi-meter option, the parameters of the actual system setup are used. In
the scan visualization and export modes, the parameters stored in the corresponding document files are
used.
The first step of the evaluation is a linearization of the filtered input signal to account for the compression
characteristics of the detector diode. The compensation depends on the input signal, the diode type and
the DC-transmission factor from the diode to the evaluation electronics. If the exciting field is pulsed, the
crest factor of the signal must be known to correctly compensate for peak power. The formula for each
channel can be given as:

     SAR SYSTEM MEASUREMENT PROCEDURES
     The procedure for assessing the peak spatial-average SAR value consists of the following steps:
     • Power Reference Measurement
     The reference and drift jobs are useful jobs for monitoring the power drift of the device under test in
     the batch process. Both jobs measure the field at a specified reference position, at a selectable
     distance from the phantom surface. The reference position can be either the selected section’s grid
     reference point or a user point in this section. The reference job projects the selected point onto the
     phantom surface, orients the probe perpendicularly to the surface, and approaches the surface using
     the selected detection method.
     • Area Scan
     The area scan is used as a fast scan in two dimensions to find the area of high field values, before
     doing a finer measurement around the hot spot. The sophisticated interpolation routines implemented
     in DASY4 software can find the maximum locations even in relatively coarse grids. This grid is
     anchored at the grid reference point of the selected section in the phantom. When the area scan’s
     property sheet is brought-up, grid settings can be edited by a user. When an area scan has
     measured all reachable points, it computes the field maximum found in the scanned area, within a
     range of the global maximum. If only one Zoom Scan follows the Area Scan, then only the absolute
     maximum will be taken as reference. For cases where multiple maximums are detected, the number
     of Zoom Scans has to be increased accordingly.
     • Zoom Scan
     Zoom scans are used to assess the peak spatial SAR values within a cubic averaging volume
     containing 1 g and 10 g of simulated tissue. The default zoom scan measures 5 x 5 x 7 points within
     a cube whose base faces are centered around the maximum found in a preceding area scan job
     within the same procedure. If the preceding Area Scan job indicates more then one maximum, the
     number of Zoom Scans has to be enlarged accordingly. For dosimetric application, it is necessary to
     assess the peak spatial SAR value averaged over a volume. For this purpose, fine resolution volume
     scans need to be performed at the peak SAR location(s) determined during the Area Scan.
     • Power Drift measurement
     The drift job measures the field at the same location as the most recent reference job within the same
     procedure, and with the same settings. The drift measurement gives the field difference in dB from
     the reading conducted within the last reference measurement. Several drift measurements are
     possible for one reference measurement. This allows a user to monitor the power drift of the device
     under test within a batch process. In the properties of the Drift job, the user can specify a limit for the
     drift and have DASY4 software stop the measurements if this limit is exceeded.
     • Z-Scan
     The Z Scan job measures points along a vertical straight line. The line runs along the Z-axis of a one-
     dimensional grid. A user can anchor the grid to the current probe location. As with any other grids,
     the local Z-axis of the anchor location establishes the Z-axis of the grid.

     SPATIAL PEAK SAR EVALUATION
     The procedure for spatial peak SAR evaluation has been implemented according to the IEEE1529
     standard. It can be conducted for 1 g and 10 g.
     The DASY4 system allows evaluations that combine measured data and robot positions, such as:
        • maximum search
        • extrapolation
        • boundary correction
        • peak search for averaged SAR
     During a maximum search, global and local maximum searches are automatically performed in 2-D
     after each Area Scan measurement with at least 6 measurement points. It is based on the evaluation
     of the local SAR gradient calculated by the Quadratic Shepard’s method. The algorithm will find the
     global maximum and all local maxima within -2 dB of the global maxima for all SAR distributions.
     Extrapolation
     Extrapolation routines are used to obtain SAR values between the lowest measurement points and
     the inner phantom surface. The extrapolation distance is determined by the surface detection
     distance and the probe sensor offset. Several measurements at different distances are necessary for
     the extrapolation.
     Extrapolation routines require at least 10 measurement points in 3-D space. They are used in the
     Cube Scan to obtain SAR values between the lowest measurement points and the inner phantom
     surface. The routine uses the modified Quadratic Shepard’s method for extrapolation. For a grid
     using 5x5x7 measurement points with 5mm resolution amounting to 343 measurement points, the
     uncertainty of the extrapolation routines is less than 1% for 1 g and 10 g cubes.
     Boundary effect
     For measurements in the immediate vicinity of a phantom surface, the field coupling effects between
     the probe and the boundary influence the probe characteristics. Boundary effect errors of different
     dosimetric probe types have been analyzed by measurements and using a numerical probe model.
     As expected, both methods showed an enhanced sensitivity in the immediate vicinity of the boundary.
     The effect strongly depends on the probe dimensions and disappears with increasing distance from
     the boundary. The sensitivity can be approximately given as:




     Since the decay of the boundary effect dominates for small probes (a<<λ), the cos-term can be
     omitted. Factors Sb (parameter Alpha in the DASY4 software) and a (parameter Delta in the DASY4
     software) are assessed during probe calibration and used for numerical compensation of the
     boundary effect. Several simulations and measurements have confirmed that the compensation is
     valid for different field and boundary configurations.
     This simple compensation procedure can largely reduce the probe uncertainty near boundaries. It
     works well as long as:
        • the boundary curvature is small
        • the probe axis is angled less than 30_ to the boundary normal
        • the distance between probe and boundary is larger than 25% of the probe diameter
        • the probe is symmetric (all sensors have the same offset from the probe tip)
     Since all of these requirements are fulfilled in a DASY4 system, the correction of the probe boundary
     effect in the vicinity of the phantom surface is performed in a fully automated manner via the
     measurement data extraction during postprocessing.

7. MEASUREMENT RESULTS
     7.1. SIMULATING LIQUIDS PARAMETER CHECK
     The simulating liquids should be checked at the beginning of a series of SAR measurements to
     determine of the dielectric parameters are within the tolerances of the specified target values. The
     relative permittivity and conductivity of the tissue material should be within ± 5% of the values given in
     the table below. 5% may not be easily achieved at certain frequencies. Under such circumstances,
     10% tolerance may be used until more precise tissue recipes are available.
     TISSUE DIELECTRIC PARAMETERS FOR HEAD AND BODY PHANTOMS
     The head tissue dielectric parameters recommended by the IEEE SCC-34/SC-2 in P1528 have been
     incorporated in the following table. These head parameters are derived from planar layer models
     simulating the highest expected SAR for the dielectric properties and tissue thickness variations in a
     human head. Other head and body tissue parameters that have not been specified in P1528 are
     derived from the tissue dielectric parameters computed from the 4-Cole-Cole equations and
     extrapolated according to the head parameters specified in P1528.

     7.2. SYSTEM PERFORMANCE CHECK
     The system performance check is performed prior to any usage of the system in order to guarantee
     reproducible results. The system performance check verifies that the system operates within its
     specifications. The system performance check results are tabulated below. And also the
     corresponding SAR plot is attached as well in the SAR plots files.
     SYSTEM PERFORMANCE CHECK MEASUREMENT CONDITIONS
     •    The measurements were performed in the flat section of the SAM twin phantom filled with Head
          simulating liquid of the following parameters.
     •    The DASY4 system with an E-fileld probe ET3DV6 SN: 1577 was used for the measurements.
     •    The dipole was mounted on the small tripod so that the dipole feed point was positioned below
          the center marking of the flat phantom section and the dipole was oriented parallel to the body
          axis (the long side of the phantom). The standard measuring distance was 10 mm (above 1 GHz)
          and 15 mm (below 1 GHz) from dipole center to the simulating liquid surface.
     •    The coarse grid with a grid spacing of 15 mm was aligned with the dipole.
     •    Special 5 x 5 x 7 fine cube was chosen for cube integration(dx=dy=7.5mm; dz=5mm).
     •    Distance between probe sensors and phantom surface was set to 4 mm.
     •    The dipole input power (forward power) was 250 mW±3%.
     •    The results are normalized to 1 W input power.
     REFERENCE SAR VALUES
     The system performance check is performed prior to any usage of the system in order to guarantee
     reproducible results. The system performance check verifies that the system operates within its
     specifications of ±10%. The system performance check results are tabulated below. And also the
     corresponding SAR plot is attached as well in the SAR plots files.
