Note: *Defined as a tissue volume in the shape of a cube

Table 3: SAR limits specified in IEEE Standard C95.1-2005 and Health Canada’s Safety Code 6.

In this report the comparison between the exposure limits and the measured data is made using the spatial
peak SAR; the power level of the device under test guarantees that the whole body averaged SAR is not
exceeded.

2.2 Exposure Categories
General Public / Uncontrolled Exposure
General population comprises individuals of all ages and of varying health status, and may include particularly susceptible groups or
individuals. In many cases, members of the public are unaware of their exposure to electromagnetic fields. Moreover, individual
members of the public cannot reasonably be expected to take precautions to minimize or avoid exposure.

Occupational / Controlled Exposure
The occupationally exposed population consists of adults who are generally exposed under known conditions and are trained to be
aware of potential risk and to take appropriate precautions.

Table 4: RF exposure categories.

2.3 Distinction between Maximum Permissible Exposure and SAR Limits
The biological relevant parameter describing the effects of electromagnetic fields in the frequency range of
interest is the specific absorption rate SAR (dimension: power/mass). It is a measure of the power absorbed
per unit mass. The SAR may be spatially averaged over the total mass of an exposed body or its parts. The
SAR is calculated from the r.m.s. electric field strength E inside the human body, the conductivity  and the
mass density  of the biological tissue:

 T /  t as a function of the specific
SAR_Report_FCC_ISED_Body_v2.1

The specific absorption rate describes the initial rate of temperature rise
heat capacity c of the tissue. A limitation of the specific absorption rate prevents an excessive heating of the
human body by electromagnetic energy.

As it is sometimes difficult to determine the SAR directly by measurement (e.g. whole body averaged SAR),
the standard specifies more readily measurable maximum permissible exposures in terms of external electric
E and magnetic field strength H and power density S, derived from the SAR limits. The limits for E, H and S
444/AR

have been fixed so that even under worst case conditions, the limits for the specific absorption rate SAR are
not exceeded.

4 Measurement Procedure

4.1 General Requirement
The test shall be performed in a laboratory with an environment which avoids influence on SAR
measurements by ambient EM sources and any reflection from the environment itself. The ambient
temperature shall be in the range of 20°C to 26°C and 30-70% humidity. All tests have been conducted
according the latest version of all relevant KDBs.

4.2 Measurement Procedure
The following steps are used for each test position:

 Establish a call with the maximum output power with a base station simulator. The connection
between the mobile phone and the base station simulator is established via air interface.
 Measurement of the local E-field value at a fixed location (P1). This value serves as a reference
value for calculating a possible power drift.
 Measurement of the SAR distribution with resolution settings for area scan and zoom scan according
KDB 865664 D01 as shown in Table 5.
 The used extrapolation and interpolation routines are all based on the modified Quadratic Shepard´s
method [DASY4].
 Repetition of the E-field measurement at the fixed location (P1) and repetition of the whole
procedure if the two results differ by more than  0.21dB.

4.3 Additional Information for IEEE 802.11 (WiFi) Transmitters
For both DSSS and OFDM wireless modes an Initial Test Position must be established for each applicable
exposure configuration using either:

 Design implementation defined by the manufacturer, or

 Investigative results by the test lab based on:

o Exclusions based on the distance from the antenna to the surface, or

o Highest measured SAR from the area-scan-only measurements on all applicable test
positions at the Initial Test Configuration, if found to require SAR tests.

Then, the initial test position procedure defines the required complete SAR scan measurements on each
exposure configuration as following:

 When the reported SAR of the initial test position is ≤ 0.4 W/kg, further SAR measurements is not
required for the remaining test positions in that configuration as well as 802.11 transmission mode
combinations within the frequency or aggregated band.

 When the reported SAR of the initial test position is > 0.4 W/kg, further SAR measurements is
required in the initial test position or next closest/smallest test separation distance based on
manufacturer justification, on the following highest maximum output power channel, until the
reported SAR is ≤ 0.8 W/kg or all required test positions are tested.

 When the reported SAR for all initial and subsequent test positions is > 0.8 W/kg, further SAR
measurements is required on these positions on the subsequent next highest measured output
power channels, until the reported SAR is ≤ 1.2 W/kg or all required channels have been tested.

For OFDM transmission configurations in 2.4 GHz and 5 GHz bands, it is important to determine SAR Initial
Test Configuration for each stand alone and aggregated frequency band according to the maximum output
power and tune-up tolerance specified for production units. The procedure is as following:

 Highest output power channel is chosen; if there are channels with same maximum output power
then the closest to the mid-band frequency is preferred. If there are more than one channel with
same maximum output power and same distance to the mid-band frequency, then the channel with
the higher frequency is preferred.

 When SAR measurement is required for a subsequent test configuration and the channel bandwidth
SAR_Report_EN50566_EN62209-2_1.0.docx/09.06

is smaller than that in the initial test configuration, all channels in the subsequent test configuration
that overlap with the larger bandwidth channel tested in the initial test configuration should be used
to determine the highest maximum output power channel in the subsequent test configuration.
SAR_Report_FCC_ISED_Body_v2.1

Along with the initial test position reduction guidelines, the following procedures are also applied to SAR
measurement requirements when multiple OFDM configurations are supported:

 When the reported SAR of the initial test configuration with the highest output power channel is > 0.8
W/kg, further SAR measurements is required for next highest output power channel in the initial test
configuration, until the reported SAR is ≤ 1.2 W/kg or all required channels have been tested.

 When the reported SAR of the subsequent test configuration with the highest output power channel
is > 1.2 W/kg, further SAR measurements is required for next highest output power channel in this
test configuration, until the reported SAR is ≤ 1.2 W/kg or all required channels have been tested.

 When the reported SAR of the subsequent test configuration is > 1.2 W/kg, further SAR
measurements for the following subsequent test configurations are required.

4.4 Measurement Variability
According KDB 865664 repeated measurements are required only when the measured SAR is ≥ 0.80 W/kg.
If the measured SAR value of the initial repeated measurement is < 1.45 W/kg with ≤ 20% variation, only one
repeated measurement is required to reaffirm that the results are not expected to have substantial variations,
which may introduce significant compliance concerns. A second repeated measurement is required only if
the measured result for the initial repeated measurement is within 10% of the SAR limit and vary by more
than 20%, which are often related to device and measurement setup difficulties. The following procedures
are applied to determine if repeated measurements are required.

1) Repeated measurement is not required when the original highest measured SAR is < 0.80 W/kg;
steps 2) through 4) do not apply.

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.

5.4 Tissue Simulating Liquid Parameters
For the measurement of the following parameters the Speag DAK-3.5 dielectric probe kit is used,
representing the open-ended coaxial probe measurement procedure.

Recommended values for the dielectric parameters of the tissue simulating liquids are given in IEEE 1528
and FCC published RF Exposure KDB Procedures. All tests were carried out using liquids with dielectric
parameters within +/- 5% of the recommended values. The dielectric properties of the tissue simulating liquid
have been measured within 24 h before SAR testing. The depth of the tissue simulant was at least 15.0 cm
for all system check and device tests, measured from the ear reference point in case of the SAM phantom
and from the inner surface of the flat phantom.

6.3.2 Output Power Values for 3G
For measurements in WCDMA, without HSDPA or HSUPA, the default test configuration is to establish a
radio link between the DUT and a communication test set using a 12.2 kbps RMC configured Test Loop
Mode 1 and TPC bits configured to all “1”. The SAR will be tested for all bands using a Rel99 call configured
to transmit at maximum output power per 3GPP 34.121 [3GPP 34.121]. The Rel99 parameters are
summarized in Table 14.

WCDMA was tested in RMC mode without HSPA. According KDB 941225 D01 HSPA SAR is not required
when the averaged output power of the HSPA subtests are not higher than 0.25 dB then measured in RMC
mode and the assessed SAR value in this mode is not higher than 1.2 W/kg.

6.4 Standalone SAR Test Exclusion
SAR test exclusion is determined for the EUT according to KDB 447498 D01 with 1g SAR exclusion
thresholds for 100 MHz to 6GHz at test separation distances ≤ 50 mm determined by:
[(max power of channel. incl. tune-up tolerance. mW) / (min test separation distance. mm)] * [√f(GHz)]
≤ 3.0 for 1g SAR and ≤ 7.5 for 10g extremity SAR, where

• f(GHz) is the RF channel transmit frequency in GHz
• Power and distance are rounded to the nearest mW and mm before calculation
• The result is rounded to one decimal place for comparison

When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test
exclusion.

Notes: According to the customer’s requirements SAR measurements have been performed for all supported bands on the back side
of DUT (body supported / lap-held conditions). BT test has been excluded due to the output power below the given threshold.

Table 16: SAR test exclusion for body-supported exposure configuration against different device edges according to KDB 447498.

When the standalone SAR test exclusion applies to an antenna that transmits simultaneously with other
antennas the standalone SAR must be estimated according to KDB 447498 in order 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 and x = 18.75 for 10-g SAR
SAR_Report_EN50566_EN62209-2_1.0.docx/09.06

When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test
exclusion.
 0.4 W/kg for 1g SAR and 1.0 W/kg for 10g SAR. when the test separation distance is > 50 mm

7 SAR Test Results

The tables below contain the measured SAR values averaged over a mass of 1g. SAR assessment was
conducted in the worst case configuration with output power values according to Table 13 – Table 15.
According to KDB 447498 D01, the reported SAR is the measured SAR value adjusted for maximum tune-
up tolerance limit shown in Table 12.

Reported SAR is calculated by the following formulas:
 Scaling factor tune up limit = tune-up limit power (mW) / RF power (mW)
 Scaling factor max. duty cycle = max. possible duty cycle / used duty cycle for SAR measurement
 Reported SAR = measured SAR * scaling factor tune up limit * scaling factor max. duty cycle

The plots with the highest measured SAR values are shown in Appendix B - SAR Distribution Plots.

General Note:

According to the declaration of the manufacturer the Tempus Pro device is intended to be used in body-
supported conditions (lap-held) with the back or bottom side towards the human body. Therefore, only two
sides of DUT have been considered for testing. The bottom side of DUT has been excluded from testing
according to Table 16.

Measured maximum SAR is < 0.8 W/kg, thus measurement variability assessment according to
KDB 865664 is not applicable.

Notes: Only WWAN + BT or WLAN + BT antennas are able to transmit simultaneously.
Table 19: Simultaneous transmission capabilities.

For the following simultaneous transmission analysis the worst case SAR results shown in Table 17 –
Table 18 have been used.

According to KDB 447498, the following table gives an overview about the ∑SAR for simultaneous
transmitting modes. When ∑SAR > 1.6 W/kg. a SAR test exclusion is determined by the SAR to peak
location separation ratio.
