Guangzhou Branch Our company is applying for certification for the electric breast pump product models, each model can be differentiated by the suffix "-x" to indicate different colors (x = blank, 1 to 12) Models: 598-x, 518-x (-x=blank, -1, -2, -3, -4, -5, -6, -7, -8, -9, -10, -11, -12, indicates different colour) FCC ID: 2BSODWBP518 Difference Explanation The two series models 598-x, 518-x are identical except the appearance. All models used same Bluetooth module. The same series models only different in their exterior color appearance. Their electrical structure, key components, circuit design, and Bluetooth module are completely identical. We hereby confirm that the content of this statement is true and accurate, and we assume full responsibility for any consequences arising from misrepresentation or omission.

Introduction 598-x, 518-x (-x=blank, -1, -2, -3, -4, -5, -6, -7, -8, -9, -10, -11, -12, indicates different colour) are electric breast pump, which contain Bluetooth function inside. FCC ID: 2BSODWBP518 2. Limit and Guidelines on Exposure to Electromagnetic Fields According to §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 v06, 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 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 Tune up power = 1.995mW (3dBm) Distance = 5 mm f = 2.480 GHz [1.995/5] * SQRT(2.480) =0.63 0.63 ≤ 3.0 Therefore, excluded from SAR testing.
