SAR/ RF exposure review : Question #5: Please provide a clear copy of SAR data plots. It is very difficult to review alll the detail information based upon the qualify of image. Ans. It has been improved in the new edition (Rev.01) of the report. Question #6: SAR System performance check with head liquid : Per page 15 of 72 of SAR test report, the 1900MHz liquid parameter for head is used for 1800MHz head System validation tests. Please explain why 1900MHz liquid parameter is used for 1800MHz system validation. Ans. We use the same recipe for head liquid in a frequency range from 1700MHz to 2000MHz. (please refer to page14 of SAR test report.) Before SAR test, we measured the parameters of the liquid and make sure of that the parameters of the liquid in the range of 5% of the target for all of Tx. frequency range of DUT and the frequency of system validation. So, in this case, the liquid got valid parameters from 1789MHz – 1910MHz. (please refer to Appendix A of this document.) And we use the parameter at 1800MHz for System validation to validate our system accuracy. (according to OET65 Supplement C, it’s valid.) Question #7: SAR System perform check with body liquid: per page 15 of 72 of SAR test report, the 1800MHz body parameter does not match with page 15 of 72 information. Please explain. Ans. That was a typing error. The parameters which in the list should be corrected to the mid-band frequency of the DUT. To avoid confusion, we modified the list and update a new edition (Rev.01) of the report. Question #8: Appendix B of SAR test data: By comparing channel 25 , channel 600 and channel 1175 which measured at the same day but the liquid parameter are different. Please explain. Ans. In DASY4 V4.1 Build47, it is possible to import whole liquid dielectric parameters for each frequency. Then the DASY4 software can automatically calculate the conductivity and input it according to the channel selected in communication system. That is why the parameters are different for each Channel. (p lease refer to the Appendix B of this document.) For further accuracy, we measured the liquid in frequency range 1700 – 1910MHz per 1MHz a nd import the measured result. Then the DASY4 software will automatically input the parameter according to the selected channel of the communication system. (please refer to Appendix A of this document.) © 2003 Auden Techno. Corp.

Question #9 : Appendix B of SAR test data : there are three sets of liquid parameter were used : 1.40297/39.7664; 1.4343/39.62; and 1.46214/39.4806. Please explain when liquid was calibrated. W hy three sets of liquid parameter were used for differnt channel and the relation of thess liquid parameter in comparing to page 15 of 72 of SAR test report. Please refer to the answer below Question #8 Question #10: The conversion factor used based upon the probe calibration file is for 1800MHz. Please explain why 1800MHz factor was used for 1900MHz measurement. Based upon OET 65 supplement C, 1900MHz factor shall be used. Ans. According to the page 2 of the Calibration certificate of the probe SN1720 and SN1753 which was been attached in SAR test report. The conversion factor is valid for f=1710 – 1910 MHz with Head Tissue Simulating . Question #11: Multiple peak displayed on Right tilted channel 25, 600 and 1175. Please provide second peak readings per OET 65 supplement C requirements. Ans. According to the page 49 of OET65 supplement C “All peaks within 2.0 dB (58.5%) of the highest peak identified by the interpolated data should be evaluated with a fine resolution volume scan to determine the highest one-gram averaged SAR.” All the second peaks on Right tilted and Left tilted channel 25, 600 and 1175 are not within 2.0dB of the maximum peak. Please refer to Appendix C of this document. Question #12: Muliple peak displayed on Left titled channel 25, 600 and 1175. Please provide second peak readings per OET 65 supplement C requirements. Please refer to the answer of the question #11. Question #13: Please explain why the liquid parameter for body are different for all body worn measurement. Please refer to the answer below Question #8 Question #14: Per the test setup photos, when measure the body worn SAR, the cellular phone cover is opened. When the device is used for body worn operation, the cellular phone cover shall be closed. Please redo body worn SAR with cover closed. Ans. It has been corrected and re -tested. Please refer to the new edition of SAR test report. © 2003 Auden Techno. Corp. RF Testing Lab Page 2 of 18 This document shall not be reproduced except in full, without the written approval of Auden.

Question #15: The separation distance used during body worn SAR measurement is 1.5cm ( page 20 of 72) but the user manual mentioned 1cm separation distance is required. Please explain. Ans. The separation distance will be corrected in the new edition of the manual. Question #16 : Body worn waring statement contains in the user manual does not provide clear instruction for the user to follow. Based upon the statement, only tested body worn accessories can be used with the cellular phone. However, no body worn accessory was provided during the tests. Ans. There is no accessory with the cellular phone except a headset. It will be described in an accessory list in new edition of the manual. Replier: Jim Wu 2003/7/1 © 2003 Auden Techno. Corp.
