 The 1—g and 10—g SAR test exclusion thresholds for 100 MHz to 6 GHe at test separetion
distances < 50 mm are determined by:
[{max. power of channel, including tune—up tolerance, mW)(min. test separation distance,
mm}] + [/(GHz)] < 3.0 for 19 SAR and < 7.5 for 10—g extremity SAR where
1(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
The test exclusions are applicable only when the minimum test separation distance is < 50
mm and for transmission frequencies between 100 MHz and 6 GHz. When the minimum test
separation distance is < 5 mm, a distance of 5 mm is applied to determine SAtest
exclusion

 [(max. power of channel, including tune-up tolerance, mW)/(min. test separation
 distance,mm)] · [√f(GHz)]= 3.6308/5*√2.402=1.1254≤3.0


 [(mid. power of channel, including tune-up tolerance, mW)/(min. test separation
 distance,mm)] · [√f(GHz)]= 3.6308/5*√2.441=1.1345≤3.0


 [(min. power of channel, including tune-up tolerance, mW)/(min. test separation
 distance,mm)] · [√f(GHz)]= 3.6308/5*√2.480=1.1436≤3.0



 Threshold at which no SAR required is1.1436 ≤ 3.0 for 1-g SAR, Separation
 distance is 5mm.


 Conclusion: No SAR is required.
