                                          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 DQ1
 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 Smm.

According to KDB 447498, no stand-alone required for BT antenna, and no simultaneous SAR
measurement is required.
