Subject of Investigation The objective of the measurements done by CETECOM Inc. was the dosimetric assessment of one device. The tests were performed in configurations for devices operated next to a person’s body. The examinations were carried out with the dosimetric assessment system DASY52 described in Section 6. 4.1. The IEEE Standard C95.1 and the FCC Exposure Criteria The limits are set by CFR 47 FCC rule parts 1.1307 and 2.1093, following the recommendations in IEEE C95.1-1999 (ANSI/IEEE C95.1-1999), “IEEE Standard for Safety Levels with Respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz.” 4.2. SAR Limit In this report the comparison between the American exposure limits and the measured data is made using the spatial peak SAR. Having in mind a worst case consideration, the SAR limit is valid for uncontrolled environment and mobile respectively portable transmitters. The SAR values have to be averaged over a mass of 1 g (SAR1g) with the shape of a cube.

The FCC Measurement Procedure The Federal Communications Commission (FCC) requires routine dosimetric assessment of mobile telecom-communications devices, either by laboratory measurement techniques or by computational modeling, prior to equipment authorization or use. In 2001 the Commission’s Office of Engineering and Technology has released Edition 01-01 of Supplement C to OET Bulletin 65. This revised edition, which replaces Edition 97-01, provides additional guidance and information for evaluating compliance of mobile and portable devices with FCC limits for human exposure to radiofrequency emissions. The following KDB Publications have also been used: 447498 D01 v04 – Mobile and portable device RF Exposure Procedures 648474 D01 v01r05 – SAR Evaluation Considerations for Handsets with Multiple Transmitters 248227 D01 v01r02 – SAR Measurement Procedures for 802.11 a/b/g Transmitters 941225 D01 v02 – SAR Measurement Procedures for 3G Devices 941225 D06 v01 – Hot Spot SAR 450824 D01 v01r01 – SAR Probe Calibration and System Verification Considerations for Measurements at 150 MHz – 3 GHz 450824 D02 v01r01 – Dipole Requirements for SAR System Validation and Verification 941225 D03 v01 – Recommended SAR Test Reduction Procedures for GSM/GPRS/EDGE 5.1. General Requirements SAR evaluation was 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 was in the range of 20°C to 26°C and 30-70% humidity. Simulating liquid temperature did not deviate more than +/- 2°C throughout SAR evaluation. 5.2. Body-worn and Other Configurations Phantom Requirements For body-worn and other configurations a flat phantom shall be used which is comprised of material with electrical properties similar to the corresponding tissues. Test Position The body-worn configurations shall be tested with the supplied accessories (belt-clips, holsters, etc.) attached to the device in normal use configuration. Devices with a headset output shall be tested with a connected headset. Test to be Performed For purpose of determining test requirements, accessories may be divided into two categories: those that do not contain metallic components and those that do. For multiple accessories that do not contain metallic components, the device may be tested only with that accessory which provides the closest spacing to the body. For multiple accessories that contain metallic V3.0 2010-12-30 This report shall not be reproduced except in full without the written approval of: CETECOM Inc.

Test Report #: SAR_INTEL_023_12001_FCC_rev1 FCC ID: O2Z-BTXZ0 Date of Report : 2012-12-04 Page 10 of 30 components, the device must be tested with each accessory that contains a unique metallic component. If multiple accessories share an identical metallic component, only the accessory that provides the closest spacing to the body must be tested. If the manufacturer provides none body- worn accessories a separation distance of 1.5 cm between the back of the device and the flat phantom is recommended. Other separation distances may be used, but they shall 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. For devices with retractable antenna the SAR test shall be performed with the antenna fully extended and fully retracted. Other factors that may affect the exposure shall also be tested. For example, optional antennas or optional battery packs which may significantly change the volume, lengths, flip open/closed, etc. of the device, or any other accessories which might have the potential to considerably increase the peak spatial-average SAR value. 5.3. Procedure for assessing the peak spatial-average SAR Step 1: Power reference measurement: Prior to the SAR test, a local SAR measurement should be taken at a user-selected spatial reference point to monitor power variations during testing. For example, this power reference point can be spaced 10 mm or less in the normal direction from the liquid-shell interface and within ± 10 mm transverse to the normal line at the ear reference point. Step 2: Area scan The measurement procedures for evaluating SAR associated with wireless handsets typically start with a coarse measurement grid in order to determine the approximate location of the local peak SAR values. This is referred to as the "area scan" procedure. The SAR distribution is scanned along the inside surface of typically half of the head of the phantom but at least larger than the areas projected (normal to the phantom’s surface) by the handset and antenna. An example grid is given in Figure 4. The distance between the measured points and phantom surface should be less than 8 mm, and should remain constant (variation less than ± 1 mm) during the entire scan in order to determine the locations of the local peak SAR with sufficient precision. The distance between the measurement points should enable the detection of the location of local maximum with an accuracy of better than half the linear dimension of the tissue cube after interpolation. The resolution can also be tested using the functions in Annex E (see E.5.2). The approximate locations of the peak SARs should be determined from area scan. Since a given amplitude local peak with steep gradients may produce lower spatial-average SAR than slightly lower amplitude peaks with less steep gradients, it is necessary to evaluate the other peaks as well. However, since the spatial gradients of local SAR peaks are a function of wavelength inside the tissue simulating liquid and incident magnetic field strength, it is not necessary to evaluate peaks that are less than – 2dB of the local maximum. Two-dimensional spline algorithms [Press, et al, 1996], [Brishoual, 2001] are typically used to determine the peaks and gradients within the scanned area. If the peak is closer than one-half of the linear dimension of the 1 g or 10 g tissue cube V3.0 2010-12-30 This report shall not be reproduced except in full without the written approval of: CETECOM Inc.

Test Report #: SAR_INTEL_023_12001_FCC_rev1 FCC ID: O2Z-BTXZ0 Date of Report : 2012-12-04 Page 11 of 30 to the scan border, the measurement area should be enlarged if possible, e.g., by tilting the probe or the phantom (see Figure 5). Figure 4 – Example of an area scan including the position of the handset. The scanned area (white dots) should be larger than the area projected by the handset and antenna. Step 3: Zoom scan In order to assess the peak spatial SAR values averaged over a 1 g and 10 g cube, fine resolution volume scans, called "zoom scans", are performed at the peak SAR locations determined during the “area scan.” The zoom scan volume should have at least 1.5 times the linear dimension of either a 1 g or a 10 g tissue cube for whichever peak spatial-average SAR is being evaluated. The peak local SAR locations that were determined in the area scan (interpolated value) should be on the centerline of the zoom scans. The centerline is the line that is normal to the surface and in the center of the volume scan. If this is not possible, the zoom scan can be shifted but not by more than half the dimension of the 1 g or a 10 g tissue cube. The maximum spatial-average SAR is determined by a numerical analysis of the SAR values obtained in the volume of the zoom scan, whereby interpolation (between measured points) and extrapolation (between surface and closest measured points) routines should be applied. A 3-D- spline algorithm [Press, et al, 1996], [Kreyszig, 1983], [Brishoual, 2001] can be used for interpolation and a trapezoidal algorithm for the integration (averaging). Scan resolutions of larger than 2 mm can be used provided the uncertainty is evaluated according to E (see E.5). In some areas of the phantom, such as the jaw and upper head region, the angle of the probe with respect to the line normal to the surface might become large, e.g., at angles larger than ± 30º (see Figure 5), which may increase the boundary effect to an unacceptable level. In these cases, a change in the orientation of the probe and/or the phantom is recommended during the zoom scan so that the angle between the probe housing tube and the line normal to the surface is significantly reduced (<30º).

Test Report #: SAR_INTEL_023_12001_FCC_rev1 FCC ID: O2Z-BTXZ0 Date of Report : 2012-12-04 Page 12 of 30 Step 4: Power reference measurement The local SAR should be measured at exactly the same location as in Step 1. The absolute value of the measurement drift (the difference between the SAR measured in Step 4 and Step 1) should be recorded in the uncertainty budget. It is recommended that the drift be kept within ± 5%. If this is not possible, even with repeat testing, additional information may be used to demonstrate the power stability during the test. Power reference measurements can be taken after each zoom scan, if more than one zoom scan is needed. However, the drift should always be referred to the initial state with fully charged battery. 5.4. Determination of the largest peak spatial-average SAR In order to determine the largest value of the peak spatial-average SAR of a handset, all device positions, configurations and operational modes should be tested for each frequency band according to steps 1 to 3 below. Step 1: The tests of 6.4 should be conducted at the channel that is closest to the center of the transmit frequency band (fc) for: a) all device positions (cheek and tilt, for both left and right sides of the SAM phantom, b) all configurations for each device position in (a), e.g. antenna extended and retracted, and c) all operational modes for each device position in (a) and configuration in (b) in each frequency band, e.g. analog and digital. If more than three frequencies need to be tested, (i.e., Nc > 3), then all frequencies, configurations and modes must be tested for all of the above positions. Step 2: For the condition providing highest spatial peak SAR determined in Step 1 conduct all tests of 6.4 at all other test frequencies, e.g. lowest and highest frequencies. In addition, for all other conditions (device position, configuration and operational mode) where the spatial peak SAR value determined in Step 1 is within 3dB of the applicable SAR limit, it is recommended that all other test frequencies should be tested as well1. Step 3: Examine all data to determine the largest value of the peak spatial-average SAR found in Steps 1 to 2.

Robot system specification The SAR measurement system being used is the SPEAG DASY52 system, which consists of a Stäubli TX90XL 6-axis robot arm and CS8c controller, SPEAG SAR Probe, Data Acquisition Electronics, and SAM Twin Phantom. The robot is used to articulate the probe to programmed positions inside the phantom to obtain the SAR readings from the EUT. The system is controlled remotely from a PC, which contains the software to control the robot and data acquisition equipment. The software also displays the data obtained from test scans. Robot DAE Probe Measurement Server Robot Controller Phantoms Figure 5: Schematic diagram of the SAR measurement system In operation, the system first does an area (2D) scan at a fixed depth within the liquid from the inside wall of the phantom. When the maximum SAR point has been found, the system will then carry out a 3D scan centered at that point to determine volume averaged SAR level.

Isotropic E-Field Probe for Dosimetric Measurements The probes are constructed using three orthogonal dipole sensors arranged on an interlocking, triangular prism core. The probes have built-in shielding against static charges and are contained within a PEEK cylindrical enclosure material at the tip. Probe calibration is described in the probe’s calibration certificate. 6.3. Data Acquisition Electronics The DAE contains a signal amplifier, multiplexer, 16bit A/D converter and control logic. It uses an optical link for communication with the DASY5 system. The DAE has a dynamic range of -100 to 300 mV. It also contains a two step probe touch detector for mechanical surface detection and emergency robot stop. 6.4. Phantoms The Twin SAM V4.0 Phantom is designed to specifications defined in IEEE 1528 and IEC 62209-1. It enables the dosimetric evaluation of left and right hand phone usage as well as body mounted usage at the flat phantom region. Additionally, the Oval Flat ELI V4.0 Phantom is designed to specification defined in IEEE 1528 and IEC 62209-2. It enables the dosimetric evaluation of body mounted usage. 6.5. Interpolation and Extrapolation schemes The interpolation, extrapolation and maximum search routines are all based on the modifed Quadratic Shepard's method. The interpolation scheme combines a least-square fitted function method and a weighted average method which are the two basic types of computational interpolation and approximation. The routines construct a once-continuously differentiable function that interpolates the measurement values.

According to SPEAG user manual section 27.2, CW can be assumed which results in crest factor 1. If the SAR value on the middle channel was more than 3dB below the limit, high and low channels were not evaluated. For GSM bands, the uplink timeslot configuration with the highest source-based time-averaged output power is used for full SAR evaluation for body exposure and wireless router mode positions. Spot check measurements for other uplink timeslot configurations are performed on the position with the highest measured SAR value to ensure compliance. SAR evaluation for wireless router mode is performed on the faces and edges that are within 2.5 cm of the transmitting antenna as required by KDB 941225 D06 v01. During the course of testing, the hardware and software of the EUT was changed. If the previous hardware/software was evaluated, spot checks with the new hardware/software version are performed on the position with the highest measured SAR. If spot check measurements using the new hardware/software version are higher than the previous hardware/software version, full testing is performed for the new hardware/software version for the exposure condition.

SAR Results Extrapolated to Upper Tolerance Limit TCB Workshop presentation “RF Exposure Procedure Review” April 2010, slide 43, states test results must demonstrate compliance when results are extrapolated to the upper tune-up tolerance limit, with respect to the maximum measured output power of the test sample, to ensure all production units are compliant. The upper tune-up tolerance is declared by the manufacturer. The table below extrapolates the measured SAR results to the upper tune-up tolerance limit of licensed bands. Only the highest SAR results of each band are shown.
