Standard Requirement
According to § 15.247(i) and § 1.1307b(1), systems operating under the provisions of this
section shall be operated in a manner that ensures that the public is not exposed to radio
frequency energy levels in excess of the Commission’s guidelines. See KDB 447498 D01
General RF Exposure Guidance v05, section 4. 3. 1.
The 1-g and 10-g SAR test exclusion thresholds for 100MHz to 6GHz at test separation
distances ≤ 50mm are determined by:
[ (max. power of channel, including tune-up tolerance, mW)/(min. test separation distance,
mm)]*[ √f(GHz)] ≤3.0 for 1-g SAR and ≤7.5 for 10-g SAR extremity SAR, where

f(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 ≤
50mm and for transmission frequencies between 100MHz and 6GHz. When the minimum test
separation distance is <5mm, a distance of 5mm is applied to determine SAR test exclusion.

Routine SAR evaluation refers to that specifically required by § 2.1093, using measurements
or computer simulation. When routine SAR evaluation is not required, portable transmitters
with output power greater than the applicable low threshold require SAR evaluation to quality
for TCB approval.
One antenna is available for the EUT (BT product). The minimum separation distance is 5mm.
