Technical Description The Equipment Under Test (EUT) is a portable transmitter of a RC Car operating at 27.145 MHz as dictated by a crystal. The EUT is powered by a 3.0V DC source (2 x 1.5V AA batteries). The EUT has a left / right control lever and a forward / backward control lever. 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 and right directions. Antenna Type: External, Dedicated Whip Antenna Antenna Gain: 0dBi Nominal rated field strength: 62.7dBμV/m at 3m Maximum allowed field strength of production tolerance: +/- 3dB The brief circuit description is listed as below: 1) U1 (TX2-4) acts as MCU 2) L3 and L4 act as an Antenna Circuit. 2) Y acts as a 27.145MHz oscillator. 3) Q1(G3Y) & Q2(945) acts as Modulator and Amplifier.

Analysis Report Report No.: 20080912 The Equipment Under Test (EUT) is a portable transmitter of a RC Car operating at 27.145 MHz as dictated by a crystal. The EUT is powered by a 3.0V DC source (2 x 1.5V AA batteries). The EUT has a left / right control lever and a forward / backward control lever. 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 and right directions. Antenna Type: External, Dedicated Whip Antenna Antenna Gain: 0dBi Nominal rated field strength: 62.7dBμV/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 65.7dBμV/m at 3m in frequency 27.145MHz, thus; The worst case of SAR Exclusion Threshold Level for 27.145MHz when the minimum test separation distance is < 50mm: = [474 * (1 + log100/f(MHz))]/2 = 371.2mW According to the KDB 412172 D01: EIRP = [(FS*D) ^2*1000 / 30] Calculated Field Strength for 371.2mW is 120.9dBuV/m @3m Since maximum field strength plus production tolerance < = 120.9dBuV/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.
