Analysis Report Report No.: 13041497HKG-001 The Equipment Under Test (EUT) is a transmitter of a RC Car operating at 27.145 MHz as dictated by a crystal. The EUT is powered by a 9.0 V DC source (1 x 9V battery). The EUT has two forward or backward control levers to control the left wheels and right wheel of the receiver of the RC Car After switching ON the EUT and the receiver of the RC Car, activating the control levers on the EUT can control the receiver moving forward, backward, left or right. Antenna Type: External integral antenna Antenna Gain: 0dBi Nominal rated field strength: 68.5dBμV/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 71.5dBμV/m at 3m in frequency 27.145MHz, thus; The EIRP = [(FS*D) ^2*1000 / 30] = 0.0042mW Conducted power = Radiated Power (EIRP) – Antenna Gain So; Conducted Power = 0.0042mW. The SAR Exclusion Threshold Level for 27.145MHz when the minimum test separation distance is < 50mm: = [474 * (1 + log100/f(MHz))]/2 = 371.2mW 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.
