FCC: According to KDB 447498 D01 Mobile and Portable Devices RF Exposure Procedures and Equipment Authorization Policies v06.
(1) Clause 4.3: General SAR test reduction and exclusion guidance Sub clause 4.31: Standalone SAR test exclusion considerations 1) The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6GHz at test separation distance5 mm are determined by:
[(max. power of channel, including tune-up tolerance, mW)/(min. test separation, mm)]*[f(GHz) ] 3.0 for 1-g SAR
[(max. power of channel, including tune-up tolerance, mW)/(min. test separation, mm)]*[f(GHz) ] 7.5.0 for 10-g SAR TB-RF-074-1.0 Report No.: TB-MPE167041 Page: 3 of 3 2. Calculation:
