Technical Description The Equipment Under Test (EUT) is portable controller for Remote controlled car set which operates at 27.145MHz. The EUT is power by 1 x 9.0V Alkaline battery. After switching on the EUT, the car will be moved forward or backward, turned left or right based on the joystick control in the controller. Antenna Type: External, Dedicated Telescope Antenna Antenna Gain: 0dBi Nominal rated field strength is 44.1dBμV/m at 3m Maximum allowed production tolerance: +/- 3dB Antenna Type: Internal, Integral antenna For electronic filing, the brief circuit description is saved with filename: descri.pdf. The brief circuit description is listed as below: 1) Y1 acts as a 27.145 MHz oscillator. 2) U1 (PT977) acts as MCU 3) Q1 & Q2 act as Modulator & Amplifier

Analysis Report The Equipment Under Test (EUT) is portable controller for Remote controlled car set which operates at 27.145MHz. The EUT is power by 1 x 9.0V Alkaline battery. After switching on the EUT, the car will be moved forward or backward, turned left or right based on the joystick control in the controller. Antenna Type: External, Dedicated Telescope Antenna Antenna Gain: 0dBi Nominal rated field strength is 44.1dBμV/m at 3m Maximum allowed production tolerance: +/- 3dB According to the KDB 447498: Based on the Maximum allowed field strength of production tolerance was 47.1dBμV/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.
