TEST REPORT Test Setup Configuration Note - The RF exposure test is performed in the shield room. - The test distance is between the edge of the charger and the geometric centre of probe. Test Equipment List Name of instrument Model Manufacturer Cal. Date Due Date MAGNETIC FIELD HiTESTER 3470 Hioki 21-Jun-15 21-Jun-16 TRF No: RF Exposure FCC ID: PYADT-904 Pages 1 of 3

Reference Limit: Environmental evaluation and exposure limit according to FCC CFR 47 part 1, 1.1307(c) and (d), 1.1310 According to FCC 1.1310: The criteria listed in the following table shall be used to evaluate the environment impact of human exposure to radio frequency (RF) radiation LIMITS FOR MAXIMUM PERMISSIBLE EXPOSURE (MPE) Frequency Electric field Magnetic Field Power Density Average Time Range strength Strength 2 (mW/cm ) (minutes) (MHz) (V/m) (A/m) (A) Limits for Occupational/Controlled Exposure 0.3 – 3.0 614 1.63 (100)* 6 (B) Limits for General Population/Uncontrolled Exposure 0.3 – 1.34 614 1.63 (100)* 30 Note: * = Plane wave equivalent power density Test Mode: Wireless charger and Bluetooth function transmitting simultaneously. Test Result: H-Field Strength at 10 cm from the edges surrounding the EUT Frequency Probe Probe Probe Probe Probe Limits Range Position A Position B Position C Position D Position E (A/m) (MHz) (A/m) (A/m) (A/m) (A/m) (A/m) 0.110~0.150 0.036 0.016 0.018 0.002 0.026 1.63 E-Field Strength (calculated) at 10 cm from the edges surrounding the EUT Frequency Probe Probe Probe Probe Probe Limits Range Position A Position B Position C Position D Position E (V/m) (MHz) (V/m) (V/m) (V/m) (V/m) (V/m) 0.110~0.150 13.57 6.03 6.79 0.75 9.80 614 Note: 1. E= 377* H, E = electric field strength (V/m), H = magnetic field strength (A/m) 2. The maximum E-field Strength at 3m is 78.7dBuV/m, According to FCC KDB 412172D01: The EIRP = (FS*D) ^2 / 30 = -16.5 dBm TRF No: RF Exposure FCC ID: PYADT-904 Pages 2 of 3

Configuration photo of the test: 1. Measuring distance 10 cm For BLE 4.0 Portion: Modulation Type: GFSK. Antenna Type: Integral antenna. The nominal conducted output power specified: —3dBm +3dB. According to the KDB 447498: The maximun conducted output power specified is OdBm = 1.0mW The source— based time—averaging conducted output power = 1.0* Duty Cycle mW= 1.0mW The SAR Exclusion Threshold Level: = 3.0 * (min. test separation distance, mm) / sqrt(freq. in GHz) =3.0 * 5 / sqrt (2.480) mW =9.5 mW Since the source—based time—averaging conducted output power is well below the SAR low threshold level, so the EUT is considered to comply with SAR requirement without testing. According to section 4.3.2 of KDB 447498 DO1, standalone SAR was estimated according to the following to determine simultaneous transmission SAR test exclusion {max. power of channel, including tune—up tolerance, mW)/{min. test separation distance, mm)] * [ / f(GHz)/x] Wi/kg = 1.0 * [sqrt (2.480) / 7.51/5 Wikg = 0.042 W/kg From above value, the estimated standalone Bluetooth SAR value does not exceed 1/2 of SAR limit and the measured E and H field strengths of standalone Wireless Charging operation does not exceed 1/2 of E and H field strength limits, so the quantitative simultaneous transmission analysis will not be necessary.
