Analysis Report Report No.: 19031210HKG‐002 The Equipment Under Test (EUT), is a 2.4GHz Transceiver (RC car). The sample supplied operated on 46 channels, normally at 2420 ‐ 2465MHz. The channel is separated by 1 MHz channel spacing. The EUT is powered by 1 x 9.6V rechargeable battery. After switch on the EUT, the car will be moved forward or backward, turned left or right based on the switches pressed in the controller. Antenna Type: Internal, Integral Antenna Type: Internal integral antenna Antenna Gain: 0dBi Nominal rated field strength (Peak): 89.8dBμV/m at 3m Nominal rated field strength (Average): 65.6dBμV/m at 3m Maximum allowed field strength of production tolerance: +/- 3dB According to the KDB 447498: Based on the Average allowed field strength of production tolerance was 68.6dBμV/m at 3m. 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 at 3m Since average field strength plus production tolerance < = 105dBuV/m at 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.
