SAR Exclusion Justification This device FCC ID: XQCBHAWS001 is excluded from SAR testing by the following justification The maximum power that the transmitter is capable of is 0.72 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)] 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. Duty Cycle Max Peak Power (dBm) Min Separation distance (mm) Frequency (Ghz) 11.00% -1.45 5 0.90842 Value 1-g (mW) 10-g (mW) 0.14 (115) 121 "Value" is  3 , the SAR test exclusion threshold < 50mm power limits for above caclulation using specified frequency 1-g power limit 10-g power limit 157 393 “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 SAREXJUST-B-0-43 REV A 01/21/2014
