INTERTEK TESTING SERVICES RF Exposure The equipment under test (EUT) is a EXP Controller with Bluetooth 5.0 BLE function operating in 2402-2480MHz. The EUT is powered by DC 3.7V by rechargeable battery and charged by DC 5V through adapter. For more detail information pls. refer to the user manual. Antenna Type: Integral antenna Modulation Type: GFSK Antenna Gain: 0dBi Bluetooth Version: 5.0 BLE (Single Mode) The nominal conducted output power specified: 0.0 dBm (±3dB) The nominal radiated output power (e.i.r.p) specified: 0.0 dBm (±3dB) According to the KDB 447498: The Maximum peak radiated emission for the EUT is 97.4 dBμV/m at 3m in the frequency 2480MHz The EIRP = [(FS*D) ^2 / 30] mW = 2.17dBm which is within the production variation. The Minimum peak radiated emission for the EUT is 97.2 dBμV/m at 3m in the frequency 2402MHz The EIRP = [(FS*D) ^2 / 30] mW = 1.97dBm which is within the production variation. The maximum conducted output power specified is 3dBm= 1.995mW The source- based time-averaging conducted output power =1.995* Duty cycle mW <1.995 mW(Duty cycle <100%) The SAR Exclusion Threshold Level: 푃 th (mW) = ERP 20cm * (푑/20cm) 푥 (X= ) = 3060 * (0.5/20) 1.9 mW = 2.72 mW Since max. power of the source-based time-averaging conducted output power and effective radiated power (ERP) is well below the SAR low threshold level, so the EUT is considered to comply with SAR requirement without testing.
