SAR Exclusion Justification This device FCC ID: is excluded from SAR testing by the following justification The maximum power that the transmitter is capable of is 0.21 mW Using the following formula from section 4.3.1 of KDB 447498 at test separation distances ≤ 50 mm [(max. power of channel, including tune-up tolerance, mW) / (min. test separation distance, mm)] * [ √ f(GHz)] Duty Cycle 100.00% V alue 1-g (mW) 10-g (mW) 0.07 (354) -211 "Value" is  3 , the SAR test exclusion threshold 1-g power limit 10-g power limit 96 239 “source-based” time-averaging based on an inherent property or duty-cycle of a device is allowed. An example of this is the determination of exposure from a device that uses digital technology such as a time-division multiple-access (TDMA) scheme for transmission < 50mm power limits for above caclulation using specified frequency O4O-EYFPA Max Peak Power (dBm) Min Separation distance (mm) Frequency (Ghz) When the minimum test separation distance is < 5 mm, a distance of 5 mm according to 5) in section 4.1 is applied to determine SAR test exclusion. 2.465 5 -6.72 SAREXJUST-B-0-43 REV A 01/21/2014
