REFERENCE, STANDARDS, AND GUILDELINES
FCC:
The Report and 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
as recommended by the ANSI/IEEE standard C95.1-1992 [6] for an uncontrolled environment (Paragraph
65). 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.
This report describes the methodology and results of experiments performed on wireless data terminal. The
objective was to determine if there is RF radiation and if radiation is found, what is the extent of radiation
with respect to safety limits. SAR (Specific Absorption Rate) is the measure of RF exposure determined by
the amount of RF energy absorbed by human body (or its parts) – to determine how the RF energy couples
to the body or head which is a primary health concern for body worn devices. The limit below which the
exposure to RF is considered safe by regulatory bodies in North America is 1.6 mW/g average over 1 gram
of tissue mass.
CE:
The order requires routine SAR evaluation prior to equipment authorization of portable transmitter devices,
including portable telephones. For consumer products, the applicable limit is 2 mW/g as recommended by
EN62209-1 for an uncontrolled environment. According to the Standard, 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.

exposure to RF is considered safe by regulatory bodies in Europe is 2 mW/g average over 10 gram of tissue
mass.
The test configurations were laid out on a specially designed test fixture to ensure the reproducibility of
measurements. Each configuration was scanned for SAR. Analysis of each scan was carried out to
characterize the above effects in the device.

DESCRIPTION OF TEST SYSTEM
These measurements were performed with the automated near-field scanning system DASY5 from Schmid
& Partner Engineering AG (SPEAG) which is the Fifth generation of the system shown in the figure
hereinafter:
DASY5 System Description
The DASY5 system for performing compliance tests consists of the following items:
SAR Evaluation Report
9 of 45
Bay Area Compliance Laboratories Corp. (Dongguan)
Report No: RSZ170418017-20
A standard high precision 6-axis robot with controller, teach pendant and software. An arm extension
for accommodating the data acquisition electronics (DAE).
An isotropic field probe optimized and calibrated for the targeted measurement.
A data acquisition electronics (DAE) which performs the signal application, 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 from optical to electrical signals for the
digital communication to the DAE. To use optical surface detection, a special version of the EOC is
required. The EOC signal is transmitted 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.
The Light Beam used is for probe alignment. This improves the (absolute) accuracy of the probe
positioning.
A computer running Win7 professional operating system and the DASY52 software.
Remote control and teach pendant as well as additional circuitry for robot safety such as warning
lamps, etc.
The phantom, the device holder and other accessories according to the targeted measurement.
DASY5 Measurement Server
The DASY5 measurement server is based on a PC/104 CPU
board with a 400MHz Intel ULV Celeron, 128MB chip-disk
and 128MB RAM. The necessary circuits for communication
with the DAE4 (or DAE3) electronics box, as well as the 16
bit AD-converter system for optical detection and digital I/O
interface are contained on the DASY5 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 of 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 an expansion port which is reserved for
future applications. Please note that this expansion port does not have a standardized point out, and
therefore only devices provided by SPEAG can be connected. Devices from any other supplier could
seriously damage the measurement server.
Data Acquisition Electronics
The data acquisition electronics (DAE4) consist 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
with a 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 both the DAE4 as well as of the DAE3 box is 200MOhm; the inputs are
symmetrical and floating. Common mode rejection is above 80 dB.

SAM Twin Phantom
The SAM twin phantom is a fiberglass shell phantom with
2mm shell thickness (except the ear region, where shell
thickness
increases to 6 mm). The phantom has three measurement areas:
_ Left Head
_ Right Head
_ Flat phantom
The phantom table for the DASY systems based on the
robots have the size of 100 x 50 x 85 cm (L x W x H).
For easy dislocation these tables have fork lift cut outs at the
bottom.
The bottom plate contains three pairs of bolts for locking the
device holder. The device holder positions are adjusted to the
standard measurement positions in the three sections. Only one device holder is necessary if two phantoms
are used (e.g., for different liquids)
A white cover is provided to cover the phantom during off-periods to prevent water evaporation and
changes in the liquid parameters. Free space scans of devices on top of this phantom cover are possible.
Three reference marks are provided on the phantom counter. These reference marks are used to teach the
absolute phantom position relative to the robot.

Robots
The DASY5 system uses the high precision industrial robot. The robot offers the same features important
for our application:
z High precision (repeatability 0.02mm)
z High reliability (industrial design)
z Low maintenance costs (virtually maintenance free due to direct drive gears; no belt drives)
z Jerk-free straight movements (brushless synchrony motors; no stepper motors)
z Low ELF interference (motor control fields shielded via the closed metallic construction shields)
The above mentioned robots are controlled by the Staubli CS8c robot controllers. All information regarding
the use and maintenance of the robot arm and the robot controller is contained on the CDs delivered along
with the robot. Paper manuals are available upon request direct from Staubli.
Area Scans
Area scans are defined prior to the measurement process being executed with a user defined variable
spacing between each measurement point (integral) allowing low uncertainty measurements to be
conducted. Scans defined for FCC applications utilize a 15mm 2 step integral, with 1.5mm interpolation
used to locate the peak SAR area used for zoom scan assessments.
Where the system identifies multiple SAR peaks (which are within 25% of peak value) the system will
provide the user with the option of assessing each peak location individually for zoom scan averaging.
Zoom Scan (Cube Scan Averaging)
The averaging zoom scan volume utilized in the DASY5 software is in the shape of a cube and the side
dimension of a 1 g or 10 g mass is dependent on the density of the liquid representing the simulated tissue.
A density of 1000 kg/m3 is used to represent the head and body tissue density and not the phantom liquid
density, in order to be consistent with the definition of the liquid dielectric properties, i.e. the side length of
the 1g cube is 10mm,with the side length of the 10g cube is 21.5mm.
When the cube intersects with the surface of the phantom, it is oriented so that 3 vertices touch the surface
of the shell or the center of a face is tangent to the surface. The face of the cube closest to the surface is
modified in order to conform to the tangent surface.
The zoom scan integer steps can be user defined so as to reduce uncertainty, but normal practice for typical
test applications (including FCC) utilize a physical step of 7 x7 x 7 (5mmx5mmx5mm) providing a volume
of 30 mm in the X & Y & Z axis.
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 described in Reference [12] and
extrapolated according to the head parameters specified in P1528.

EUT TEST STRATEGY AND METHODOLOGY
Test Positions for Device Operating Next to a Person’s Ear
This category includes most wireless handsets with fixed, retractable or internal antennas located toward
the top half of the device, with or without a foldout, sliding or similar keypad cover. The handset should
have its earpiece located within the upper ¼ of the device, either along the centerline or off-centered, as
perceived by its users. This type of handset should be positioned in a normal operating position with the
“test device reference point” located along the “vertical centerline” on the front of the device aligned to the
“ear reference point”. The “test device reference point” should be located at the same level as the center
of the earpiece region. The “vertical centerline” should bisect the front surface of the handset at its top
and bottom edges. A “ear reference point” is located on the outer surface of the head phantom on each ear
spacer. It is located 1.5 cm above the center of the ear canal entrance in the “phantom reference plane”
defined by the three lines joining the center of each “ear reference point” (left and right) and the tip of the
mouth.
A handset should be initially positioned with the earpiece region pressed against the ear spacer of a head
phantom. For the SCC-34/SC-2 head phantom, the device should be positioned parallel to the “N-F” line
defined along the base of the ear spacer that contains the “ear reference point”. For interim head
phantoms, the device should be positioned parallel to the cheek for maximum RF energy coupling. The
“test device reference point” is aligned to the “ear reference point” on the head phantom and the “vertical
centerline” is aligned to the “phantom reference plane”. This is called the “initial ear position”. While
maintaining these three alignments, the body of the handset is gradually adjusted to each of the following
positions for evaluating SAR:

Cheek/Touch Position
The device is brought toward the mouth of the head phantom by pivoting against the “ear reference point”
or along the “N-F” line for the SCC-34/SC-2 head phantom.
This test position is established:
When any point on the display, keypad or mouthpiece portions of the handset is in contact
with the phantom.
(or) When any portion of a foldout, sliding or similar keypad cover opened to its intended
self-adjusting normal use position is in contact with the cheek or mouth of the phantom.
For existing head phantoms – when the handset loses contact with the phantom at the pivoting point,
rotation should continue until the device touches the cheek of the phantom or breaks its last contact
from the ear spacer.
Cheek /Touch Position
Ear/Tilt Position
With the handset aligned in the “Cheek/Touch Position”:
1) If the earpiece of the handset is not in full contact with the phantom’s ear spacer (in the “Cheek/Touch
position”) and the peak SAR location for the “Cheek/Touch” position is located at the ear spacer region or
corresponds to the earpiece region of the handset, the device should be returned to the “initial ear position”
by rotating it away from the mouth until the earpiece is in full contact with the ear spacer.
2) (otherwise) The handset should be moved (translated) away from the cheek perpendicular to the line
passes through both “ear reference points” (note: one of these ear reference points may not physically exist
on a split head model) for approximate 2-3 cm. While it is in this position, the device handset is tilted away
from the mouth with respect to the “test device reference point” until the inside angle between the vertical
centerline on the front surface of the phone and the horizontal line passing through the ear reference point is
by 15 80°. After the tilt, it is then moved (translated) back toward the head perpendicular to the line passes
through both “ear reference points” until the device touches the phantom or the ear spacer. If the antenna
touches the head first, the positioning process should be repeated with a tilt angle less than 15° so that the
device and its antenna would touch the phantom simultaneously. This test position may require a device
holder or positioner to achieve the translation and tilting with acceptable positioning repeatability.
If a device is also designed to transmit with its keypad cover closed for operating in the head position, such
positions should also be considered in the SAR evaluation. The device should be tested on the left and right
side of the head phantom in the “Cheek/Touch” and “Ear/Tilt” positions. When applicable, each
configuration should be tested with the antenna in its fully extended and fully retracted positions. These test
configurations should be tested at the high, middle and low frequency channels of each operating mode; for
example, AMPS, CDMA, and TDMA. If the SAR measured at the middle channel for each test
configuration (left, right, Cheek/Touch, Tilt/Ear, extended and retracted) is at least 2.0 dB lower than the
SAR limit, testing at the high and low channels is optional for such test configuration(s). If the transmission
band of the test device is less than 10 MHz, testing at the high and low frequency channels is optional.

Ear /Tilt 15o Position
Test positions for body-worn and other configurations
Body-worn operating configurations should be tested with the belt-clips and holsters attached to the device
and positioned against a flat phantom in normal use configurations. Devices with a headset output should
be tested with a headset connected to the device. When multiple accessories that do not contain metallic
components are supplied with the device, the device may be tested with only the accessory that dictates the
closest spacing to the body. When multiple accessories that contain metallic components are supplied with
the device, the device must be tested with each accessory that contains a unique metallic component. If
multiple accessories share an identical metallic component (e.g., the same metallic belt-clip used with
different holsters with no other metallic components), only the accessory that dictates the closest spacing to
the body must be tested.
Body-worn accessories may not always be supplied or available as options for some devices that are
intended to be authorized for body-worn use. A separation distance of 1.5 cm between the back of the
device and a flat phantom is recommended for testing body-worn SAR compliance under such
circumstances. Other separation distances may be used, but they should not exceed 2.5 cm. In these cases,
the device may use body-worn accessories that provide a separation distance greater than that tested for the
device provided however that the accessory contains no metallic components.
Test Distance for SAR Evaluation
For this case the EUT(Equipment Under Test) is set 10mm away from the phantom, the test distance is
10mm.

SAR Evaluation Procedure
The evaluation was performed with the following procedure:
Step 1: Measurement of the SAR value at a fixed location above the ear point or central position was
used as a reference value for assessing the power drop. The SAR at this point is measured at the start
of the test and then again at the end of the testing.
Step 2: The SAR distribution at the exposed side of the head was measured at a distance of 4 mm
from the inner surface of the shell. The area covered the entire dimension of the head or radiating
structures of the EUT, the horizontal grid spacing was 15 mm x 15 mm, and the SAR distribution was
determined by integrated grid of 1.5mm x 1.5mm. Based on these data, the area of the maximum
absorption was determined by spline interpolation. The first Area Scan covers the entire dimension of
the EUT to ensure that the hotspot was correctly identified.
Step 3: Around this point, a volume of 30 mm x 30 mm x 30 mm was assessed by measuring 7x 7 x 7
points. On the basis of this data set, the spatial peak SAR value was evaluated under the following
procedure:
1) The data at the surface were extrapolated, since the center of the dipoles is 1.2 mm away
from the tip of the probe and the distance between the surface and the lowest measuring point is
1.3 mm. The extrapolation was based on a least square algorithm. A polynomial of the fourth
order was calculated through the points in z-axes. This polynomial was then used to evaluate the
points between the surface and the probe tip.
2) The maximum interpolated value was searched with a straightforward algorithm. Around this
maximum the SAR values averaged over the spatial volumes (1 g or 10 g) were computed by the
3D-Spline interpolation algorithm. The 3D-Spline is composed of three one dimensional splines
with the “Not a knot"-condition (in x, y and z-directions). The volume was integrated with the
trapezoidal-algorithm. One thousand points (10 x 10 x 10) were interpolated to calculate the
averages.
All neighboring volumes were evaluated until no neighboring volume with a higher average
value was found.
Step 4: Re-measurement of the SAR value at the same location as in Step 1. If the value changed by
more than 5%, the evaluation was repeated.

KDB 616217: The hotspot mode SAR procedures (KDB Publication 941225 D06) for handsets and UMPC
mini-tablet procedures generally do not apply to the full-size tablet devices. The standalone and
simultaneous transmission SAR tests required for tablets are more conservative than the hotspot mode use
configurations; therefore, additional testing for hotspot SAR is not required when the procedures in this
document are applied.

SAR Measurement Variability
In accordance with published RF Exposure KDB procedure 865664 D01 SAR measurement 100 MHz to 6
GHz v01. These additional measurements are repeated after the completion of all measurements requiring
the same head or body tissue-equivalent medium in a frequency band. The test device should be returned
to ambient conditions (normal room temperature) with the battery fully charged before it is re-mounted on
the device holder for the repeated measurement(s) to minimize any unexpected variations in the repeated
results
1) Repeated measurement is not required when the original highest measured SAR is < 0.80 W/kg.
2) When the original highest measured SAR is ≥ 0.80 W/kg, repeat that measurement once.
3) Perform a second repeated measurement only if the ratio of largest to smallest SAR for the
original and first repeated measurements is > 1.20 or when the original or repeated measurement
is ≥ 1.45 W/kg (~ 10% from the 1-g SAR limit).
4) Perform a third repeated measurement only if the original, first or second repeated measurement is
≥1.5 W/kg and the ratio of largest to smallest SAR for the original, first and second repeated
measurements is > 1.20.

[√f(GHz)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR, where
1. f(GHz) is the RF channel transmit frequency in GHz.
2. Power and distance are rounded to the nearest mW and mm before calculation.
3. The result is rounded to one decimal place for comparison.
4. When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR

Exemption: The distance is more than 25mm, according to KDB 941225 D06, the Standalone SAR test is not
required.
Exclusion: In normal operation mode, the Edge(s) will not be touched by the users directly, so SAR test is not
consideration.
Exclusion*: SAR test exclusion evaluation has been done above.

When standalone SAR test exclusion applies to an antenna that transmits simultaneously with other
antennas, the standalone SAR must be estimated according to following to determine simultaneous
transmission SAR test exclusion:
[(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance,mm)]·[√f(GHz)/x]
W/kg for test separation distances ≤ 50 mm;
where x = 7.5 for 1-g SAR.
When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test
