Technical Description The Equipment Under Test (EUT) is a Bluetooth device. The EUT can operate with mobile app. The Bluetooth portion occupies frequency range of 2402MHz to 2480MHz (39 channels with channel spacing of 2MHz). Antenna Type: Internal integral antenna Antenna Gain: 0dBi Nominal rated field strength: 88.8dBμV/m at 3m Maximum allowed field strength of production tolerance: +/‐ 3dB U1 CSR1010 act as the Bluetooth module of this unit. X1 (16MHz) and X2 (32.768kHz) act as the crystal of the U1

Analysis Report Report No.: 19020492HKG-001 The Equipment Under Test (EU T) is a Bluetooth device. The EUT can operate with mobile app. The Bluetooth portion occupies frequency range of 2402MHz to 2480MHz (39 channels with channel spacing of 2MHz). Antenna Type: Internal integral antenna Antenna Gain: 0dBi Nominal rated field strength: 88.8dBμV/m at 3m Maximum allowed field strength of production tolerance: +/- 3dB According to the KDB 447498: Based on the Maximum allowed field strength of production tolerance was 91.8dBμV/m at 3m in frequency 2.4GHz, thus; The EIRP = [(FS*D) ^2*1000 / 30] = 0.46mW Conducted power = Radiated Power (EIRP) – Antenna Gain So; Conducted Power = 0.46mW. The SAR Exclusion Threshold Level: = 3.0 * (min. test separation distance, mm) / sqrt(freq. in GHz) = 3.0 * 5 / sqrt (2.480) mW = 9.53 mW Since the above conducted output power is well below the SAR Exclusion threshold level, so the EUT is considered to comply with SAR requirement without testing.
