Analysis Report The Equipment Under Test (EUT), is a portable 2.4GHz Transmitter (Car Unit) for a RC Car. The sample supplied operated on 40 channels of BT 4.2 BLE only, normally at 2402 - 2480 MHz. The channels are separated with 2 MHz spacing. The EUT is powered by 6.4V rechargeable battery or 6.0V (4 x 1.5V “AA” batteries). After switch on the EUT, the car will be moved forward or backward and turned left and right based on the switches pressed in the phone application controller. Antenna Type: Internal, Integral antenna Antenna Gain: 0dBi Nominal rated field strength is 97.8 dBμV/m at 3m Maximum allowed production tolerance: +/- 3dB According to the KDB 447498: Based on the Maximum allowed field strength of production tolerance was 100.8dBμV/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 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.
