TEST FACILITY The test facilities used to collect the test data in this report is at the location of No.3,Jinshagang 1st Road, Shixia, Dalang Town, Dongguan, Guangdong, China. BTL's Test Firm Registration Number for FCC: 357015 BTL's Designation Number for FCC: CN1240 2. GENERAL CONCULUSION According to FCC KDB447498 D01, Appendix A, SAR Test Exclusion Thresholds for 100 MHz – 6 GHz and ≤ 50 mm, the 1-g and 10-g SAR test exclusion thresholds are determined by the following: [(max. power of channel, including tune-up tolerance, mW) / (min. test separation distance, mm)] · [√f(GHz)] ≤ 3.0 for 1-g SAR, and ≤ 7.5 for 10-g 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 Appendix A - SAR Test Exclusion Thresholds for 100 MHz - 6 GHz and < 50 mm MHz 5 10 15 20 25 30 35 40 45 50 mm 150 39 77 116 155 194 232 271 310 349 387 SAR Test Exclusion Thresholds (mW) 300 27 55 82 110 137 164 192 219 246 274 450 22 45 67 89 112 134 157 179 201 224 835 16 33 49 66 82 98 115 131 148 164 900 16 32 47 63 79 95 111 126 142 158 1500 12 24 37 49 61 73 86 98 110 122 1900 11 22 33 44 54 65 76 87 98 109 2450 10 19 29 38 48 57 67 77 86 96 3600 8 16 24 32 40 47 55 63 71 79 5200 7 13 20 26 33 39 46 53 59 66 5400 6 13 19 26 32 39 45 52 58 65 5800 6 12 19 25 31 37 44 50 56 62 Report No.: BTL-FCCP-3-2008C041 Page 4 of 4 3.
