TEST METHODOLOGY 2.1 FCC Limb SAR and Body SAR Test Exclusions Applied _2.4 ㎓ WiFi, 5 ㎓ WiFi Since this product is a remote control product, it is used by most users in the hand, so Limb SAR standard is applied. In addition, since this product is capable of voice recognition by the user, an exception evaluation is applied at a distance of 10 ㎜ from the Body SAR. According to the FCC KDB 447498 D01 v06 section 4.3.1, for 100 ㎒ to 6 ㎓ and test separation distances ≤ 50 ㎜, the 1-g and 10-g SAR test exclusion thresholds are determined by the following: a) For 100 ㎒ to 6 ㎓ and test separation distances ≤ 50 ㎜, the 1-g and 10-g SAR test exclusion thresholds are determined by the following: [(max. power of channel, including tune-up tolerance, ㎽) / (min. test separation distance, ㎜)] · [√f(㎓)] ≤ 3.0 for 1-g SAR, and ≤ 7.5 for 10-g extremity SAR, where : 푀푎푥 푃표푤푒푟 표푓 퐶ℎ푎푛푛푒푙 ( 푚푊 ) 푇푒푠푡 푆푒푝푎푟푎푡푖표푛 퐷푖푠푡푎푛푐푒 ( 푚푚 ) ∗ √ 퐹푟푒푞푢푒푛푐푦 ( 퐺퐻푧 ) ≤ 3.0 For 1g SAR,7.5.for 10g SAR where - f(㎓) is the RF channel transmit frequency in ㎓ - Power and distance are rounded to the nearest ㎽ and ㎜ before calculation - The result is rounded to one decimal place for comparison 1. 2.4 ㎓ WiFi Calculation Result: Tx frequency range: 2 412 ㎒ ~ 2 462 ㎒ Limb SAR Consideration Min. test separation distance: 5 ㎜ Body SAR Consideration Min. test separation distance: 10 ㎜ Maximum Output Power: 7.9 dBm (6.17 ㎽) The Highest RF channel frequency: 2 462 ㎒ For Body SAR Exclusion Mode Frequency Maximum Allowed Power Separation Distance ≤ 3.0 for 1 g SAR [㎒] [㎽] [㎜] 2.4 ㎓ WiFi 2 462 6.17 5 1.94 For Limb SAR exclusion Mode Frequency Maximum Allowed Power Separation Distance ≤ 7.5 for 10 g SAR [㎒] [㎽] [㎜] 2.4 ㎓ WiFi 2 462 6.17 5 1.94 Report No. HCT-SR-2409-FC001 F-TP22-03 (Rev. 06) Page 7 of 7 The report shall not be (partly) reproduced except…
