Test Facility The Test site used by Bay Area Compliance Laboratories Corp. (Xiamen) to collect test data is located on the Unit 102, No. 902 Meifeng South Road, Binhai West Avenue, Science and Technology Innovation Park, Torch High tech Zone XiaMen. Bay Area Compliance Laboratories Corp.

Bay Area Compliance Laboratories Corp. (Xiamen) Report No.: 2507V00610E-RF-03 Page 5 of 7 RF EXPOSURE EVALUATION Applicable Standard According to§2.1093, systems operating under the provisions of this section shall be operated in a manner that ensure that the public is not exposed to radio frequency energy level in excess of the Commission's guideline According to KDB447498 D01 General RF Exposure Guidance v06 The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances < 50 mm 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 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 3.0 and 7.5 are referred to as the numeric thresholds in the step 2 below 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 according to 5) in section 4.1 is applied to determine SAR test exclusion. Measurement Result For BT: The max conducted power including tune-up tolerance is 5 dBm (3.16 mW). [(max. power of channel, mW)/(min. test separation distance, mm)][√f(GHz)] =3.16/5*(√2.480) = 1.0< 3.0 For BLE: The max conducted power including tune-up tolerance is 3 dBm (2 mW). [(max. power of channel, mW)/(min. test separation distance, mm)][√f(GHz)] =2/5*(√2.480) = 0.6< 3.0 Result: Compliant.
