Report No. M100861_FCC_AR5B97_SAR_2.4 Page 7 of 64 *The model numbers shown T580 and TH550 are for the same product. The T580 is for commercial market (there is Port-Replicator as option). The TH550 is for consumer market (there is no Port-Replicator). 3.4 Test sample Accessories 3.4.1 Battery Types One type of Fujitsu Lithium Ion battery is used to power the EUT. Table 7 Battery Details Battery #1 Battery #2 Product No. FPCBP219 Product No. FPCBP219 V/mAh 10.8V/5800mAh V/mAh 10.8V/5800mAh Serial No. 01A-Z100702001792Z Serial No. 01A-Z091026000648Z 4.0 TEST SIGNAL, FREQUENCY AND OUTPUT POWER ATHEROS’s ART test tool was used to configure the WLAN for testing. The EUT WLAN had a total of 11 channels within the 2412 to 2462 MHz frequency band. In the frequency range 2412 MHz to 2462 MHz the EUT operates in 2 modes, OFDM and DSSS. For the SAR measurements the EUT was operating in continuous transmit mode using programming codes supplied by Fujitsu. The Bluetooth module operates over 79 channels within the frequency range 2402 to 2480 MHz. It is possible for the Bluetooth module to operate simultaneously with the WLAN module (co-transmission). However, the standalone SAR measurement for Bluetooth module was not required (See Section 13 Multiband Evaluation Considerations). The WLAN modules can be configured in a number of different data rates. It was found that the highest source based time averaged power was measured when using the lowest data rates available in each mode. This lowest data rate corresponds to 6Mbps in OFDM mode and 1Mbps in DSSS mode. The frequency span of the 2450 MHz range Band was more than 10MHz consequently; the SAR levels of the test sample were measured for lowest, centre and highest channels in the applicable modes. There were no wires or other connections to the EUT during the SAR measurements. The Transmitter power was set to be equal or higher than power specified by the manufacturer. Table 8 Frequency and Conducted Power Results Bluetooth Channel Channel *Data Rate Maximum Conducted Frequency (Mbps) Output Power MHz Measured (dBm) Channel 40 2441 N/A 3.9 4.1 Battery Status The EUT battery was fully charged prior to commencement of measurements. Each SAR test was completed within 30 minutes. The battery condition was monitored by measuring the RF field at a defined position inside the phantom before the commencement of each test and again after the completion of the test. It was not possible to perform conducted power measurements at the output of the EUT, at the beginning and end of each scan due to lack of a suitable antenna port. The uncertainty associated with the power drift was less than 12% and was assessed in the uncertainty budget.

Report No. M100861_FCC_AR5B97_SAR_2.4 Page 12 of 64 7.0 SAR MEASUREMENT PROCEDURE USING DASY4 The SAR evaluation was performed with the SPEAG DASY4 system. A summary of the procedure follows: a) A measurement of the SAR value at a fixed location is used as a reference value for assessing the power drop of the EUT. The SAR at this point is measured at the start of the test, and then again at the end of the test. b) The SAR distribution at the exposed flat section of the flat phantom is measured at a distance of 4 mm from the inner surface of the shell. The area covers the entire dimension of the EUT and the horizontal grid spacing is 15 mm x 15 mm. The actual Area Scan has dimensions of 75mm x 120mm surrounding the test EUT. Based on this data, the area of the maximum absorption is determined by Spline interpolation. c) Around this point, a volume of 30 mm x 30 mm x 30 mm is assessed by measuring 7 x 7 x 7 points. On the basis of this data set, the spatial peak SAR value is evaluated with the following procedure: (i) The data at the surface are extrapolated, since the centre of the dipoles is 2.7 mm away from the tip of the probe and the distance between the surface and the lowest measuring point is 4 mm. The extrapolation is based on a least square algorithm. A polynomial of the fourth order is calculated through the points in z-axes. This polynomial is then used to evaluate the points between the surface and the probe tip. (ii) The maximum interpolated value is searched with a straightforward algorithm. Around this maximum the SAR values averaged over the spatial volumes (1 g and 10 g) are computed using 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-direction). The volume is integrated with the trapezoidal – algorithm. One thousand points (10 x 10 x 10) are interpolated to calculate the averages. (iii) All neighbouring volumes are evaluated until no neighbouring volume with a higher average value is found. (iv) The SAR value at the same location as in Step (a) is again measured to evaluate the actual power drift.

Report No. M100861_FCC_AR5B97_SAR_2.4 Page 16 of 64 10.0 OET BULLETIN 65 – SUPPLEMENT C TEST METHOD Notebooks should be evaluated in normal use positions, typical for lap-held bottom-face only. However the number of positions will depend on the number of configurations the laptop can be operated in. The “LIFEBOOK T SERIES” can be used in either a conventional laptop position (see Appendix A1) or a Tablet configuration. The antenna location in the “LIFEBOOK T SERIES” is closest to the top of the screen when used in a conventional laptop configuration and due to the separation distances involved between the phantom and the laptop antenna, testing is not required in this position. 10.1 Positions 10.1.1 “Tablet” Position Definition (0mm spacing) The EUT was tested in the 2.00 mm flat section of the AndreT Flat phantom P 10.1 for the “Tablet” position. The Transceiver was placed at the bottom of the phantom and suspended in such way that the back of the EUT was touching the phantom. This EUT orientation simulates the PC’s normal use – being held on the lap of the user. A spacing of 0mm ensures that the SAR results are conservative and represent a worst-case position. 10.1.2 “Edge On” Position (Portrait or Landscape) The EUT was tested in the (2.00 mm) flat section of the AndreT phantom for the “Edge On” position. The Antenna edge of the Transceiver was placed underneath the flat section of the phantom and suspended until the edge touched the phantom. Refer to Appendix A for photos of measurement positions. 10.2 List of All Test Cases (Antenna In/Out, Test Frequencies, User Modes) The EUT has a fixed antenna. Depending on the measured SAR level up to three test channels with the test sample operating at maximum power were recorded. The following table represents the matrix used to determine what testing was required. All relevant provisions of KDB 447498 are applied for SAR measurements of the host system. Due to the screen size <12 inches, “Supplement to the KDB 616217” was followed for the SAR evaluation.

Report No. M100861_FCC_AR5B97_SAR_2.4 Page 17 of 64 11.0 SAR MEASUREMENT RESULTS The SAR values averaged over 1g tissue masses were determined for the sample EUT for all test configurations listed in section 10.2. 11.1 2450MHz SAR Results There are two modes of operation within the 2450MHz band, they include OFDM and DSSS modulations. As per KDB 248227 and the Table 22 Channels and Output power setting, the EUT was tested only with OFDM modulation (802.11g). Table below displays the SAR results.

The highest SAR level recorded in the 2450MHz band was 1.070 mW/g as evaluated in a 1g cube of averaging mass. This value was obtained in Primary Portrait position in OFDM mode, utilizing channel 10 (2457 MHz) and antenna B.

Report No. M100861_FCC_AR5B97_SAR_2.4 Page 18 of 64 12.0 COMPLIANCE STATEMENT The EUT was found to comply with the FCC and RSS-102 SAR requirements. The highest SAR level recorded was 1.070 mW/g for a 1g cube. This value was measured at 2457 MHz (channel 10) in the “Primary Portrait” position in OFDM modulation mode at the antenna B. This was below the limit of 1.6 mW/g for uncontrolled exposure, even taking into account the measurement uncertainty of 27.9 %.

Report No. M100861_FCC_AR5B97_SAR_2.4 Page 19 of 64 13.0 MULTIBAND EVALUATION CONSIDERATIONS Fujitsu TABLET PC, Model: T580/TH550 is equipped with WLAN (AR5B97) and Bluetooth (BSMAN3). According to the FCC SAR evaluation procedures mentioned in “Supplement to the KDB 616217” (for Tablet PC with the LCD size < 12), stand-alone SAR evaluation is NOT required when the maximum transmitter and antenna output power is less than or equal to 60/f(GHz) (Pref) The Bluetooth module in the EUT operates in the 2.4GHz range. It has a maximum output power of 2.5mW (4dBm) which is less than Pref (=60/2.4=25mW). The shortest distance between the BT module and any other transmitting antenna was 21.5cm. Because 21.5cm > 5cm, and 2.5mW < 25mW, the Bluetooth module was not considered for SAR evaluation. This is in accordance with the test reduction methods detailed in “Supplement to the KDB 616217” and KDB 447498.
