Technical Description The Equipment Under Test (EUT), is a portable 2.4GHz Bluetooth 5.0 Speaker (Speaker Unit) for a RC Speaker. This sample is Bluetooth 5.0 without supporting 2Mbps data rate. The sample supplied operated on 40 channels, normally at 2402 - 2480MHz. The channels are separated with 2MHz spacing. Another mode for the Equipment Under Test (EUT) is Bluetooth BDR/EDR. The sample supplied operated on 79 channels, normally at 2402 - 2480MHz. The channels are separated with 1MHz spacing. The EUT is powered by 1 x 3.7V Rechargeable battery. After switching on the EUT, the speaker will be playing music based on the switches pressed in smartphone controller app. Antenna Type: Internal, Integral antenna Antenna Gain: 0dBi Nominal rated field strength is 96.1dBμV/m at 3m Maximum allowed production tolerance: +/- 3dB The brief circuit description is listed as follows: 1. U1 (AC6928B) acts as RF Module 2. U3 (4054) acts as Charging circuit 3. U4 (HT6872) acts as Amplifier Module 4. J5 (MICRO_USB) acts as USB Module 5. Y2 acts as 24MHz Oscillator 6. A2 acts as antenna matching circuit 7. M1 (MIC4013) acts as Microphone

Analysis Report The Equipment Under Test (EUT), is a portable 2.4GHz Bluetooth 5.0 Speaker (Speaker Unit) for a RC Speaker. This sample is Bluetooth 5.0 without supporting 2Mbps data rate. The sample supplied operated on 40 channels, normally at 2402 - 2480MHz. The channels are separated with 2MHz spacing. Another mode for the Equipment Under Test (EUT) is Bluetooth BDR/EDR. The sample supplied operated on 79 channels, normally at 2402 - 2480MHz. The channels are separated with 1MHz spacing. The EUT is powered by 1 x 3.7V Rechargeable battery. After switching on the EUT, the speaker will be playing music based on the switches pressed in smartphone controller app. Antenna Type: Internal, Integral antenna Antenna Gain: 0dBi Nominal rated field strength is 96.1dBμV/m at 3m Maximum allowed production tolerance: +/- 3dB According to the KDB 447498: Based on the maximum field strength of production tolerance was 99.1dBμV/m at 3m in frequency 2.402GHz. Thus, it below calculated field strength according to minimum SAR exclusion threshold level as follows: The worst case of SAR Exclusion Threshold Level: = 3.0 * (min. test separation distance, mm) / sqrt(freq. in GHz) = 3.0 * 5 / sqrt (2.483.5) mW = 9.52 mW According to the KDB 412172 D01: EIRP = [(FS*D) ^2*1000 / 30] Calculated Field Strength for 9.52mW is 105dBuV/m @3m Since maximum average field strength plus production tolerance < = 105dBuV/m @3m and antenna gain is > = 0.0dBi, it is concluded that maximum Conducted Power and Field Strength are well below the SAR Exclusion threshold level, so the EUT is considered to comply with SAR requirement without testing.
