Report Number: 68.950.19.0598.01A RF exposure Estimation for WPTT 1. Introduction Product: PowerWatch Series 2 Model no.: PW07 FCC ID: 2ANY2MPW07 Options and accessories: Wireless Charger Rating: 3.85Vdc 340mAh Li-ion Rechargeable battery RF Transmission Frequency: 2402MHz-2480MHz No. of Operated Channel: 40 Modulation: GFSK Antenna Type: Integrated antenna Antenna Gain: -10.1dBi Description of the EUT: The Equipment Under Test (EUT) is a watch which support Bluetooth function operated at 2.4GHz. 2. Limit and Guidelines on Exposure to Electromagnetic Fields According to§15.247(e)(i) and §1.1307(b)(1), 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 KDB 447498 D01 Mobile Portable RF Exposure v05r02, no SAR required if power is lower than the flowing threshold: 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 calculation25 • 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 TÜV SÜD Certification and Testing (China) Co., Ltd.

Report Number: 68.950.19.0598.01A 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. 3. Calculation method [(max. power of` channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] ·[√f(GHz)] ≤ 3.0 Conducted Power + tune up tolerance =1.47mW (1.66dBm) Distance = 5 mm f = 2.402 GHz [1.47/5] * SQRT(2.402) =0.46 0.46 ≤ 3.0 Therefore, excluded from SAR testing.
