RF Exposure evaluation for FCC According to 447498 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 EUT* Name : Waterproof RGB Wireless Speaker Model Number : M17S, M27S, V100, V200, V300 Difference of model number : All models are identical except the appearance, color and model, therefore the test performed on the model M17S. EUT Function Description : Please reference user manual of this device Power Supply : DC 5V by USB DC 7.4V by Polymer Li-ion built-in battery Radio Specification : Bluetooth V5.0 Operation Frequency : 2402 MHz - 2480 MHz Modulation : GFSK, /4-DQPSK, 8DPSK Data Rate : 1 Mbps, 2 Mbps, 3 Mbps Antenna Type : Integral PCB antenna, maximum PK gain: 3.38 dBi Serial Number : N/A Dongguan Dongdian Testing Service Co., Ltd Report No.:DDT-R21030803-2E2 Page 6 of 6 Manufacturing Tolerance GFSK (Peak) Channel Channel 0 Channel 39 Channel 78 Target (dBm) -2 -3 -3 Tolerance ±(dB) 1 1 1 π/4DQPSK (Peak) Channel Channel 0 Channel 39 Channel 78 Target (dBm) -2 -3 -3 Tolerance ±(dB) 1 1 1 8DPSK (Peak) Channel Channel 0 Channel 39 Channel 78 Target (dBm) -2 -3 -3 Tolerance ±(dB) 1 1 1 Estimtion Result Worse case is as below: [2402 MHz, -1 dBm, 0.79 mW) output power] (0.79/5) ·[√2.402(GHz)] = 0.24 < 3.0 for 1-g SAR Then SAR evaluation is not required END OF REPORT
