FCC ID: QKX0017049TX Model: 51907 (Transmitter portion) Technical Description of Transmitter The transmitter operates at 49.860 MHz, and controls the corresponding receiver to move forward, backward, left and right. The circuit of the transmitter comprises of, 1. An Encoding circuit Consisting: B, F, U1 2. A RF Oscillator (49.860MHz) Consisting: Y1 3. A Filter Network Consisting: L2, L3, C5, C6 4. A RF Modulator and Amplifier Consisting: Q1, Q2 5. A Power Supply Consisting: 3.0VDC (2 x ”AA” batteries) Antenna Gain: 0dBi Nominal rated field strength: 51.2dBμV/m at 3m Maximum allowed field strength of production tolerance: +/- 3dB The transmitter uses an external and integral antenna.

Analysis Report Report No.: 13051480HKG-001 The Equipment Under Test (EUT) is a transmitter of a RC Car operating at 49.860 MHz as dictated by a crystal. The EUT is powered by a 3.0 V DC source (2 x 1.5V “AA” batteries). The EUT has 2 control buttons to control the RC car left, right, forward and backward. 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: 51.2dBμV/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 54.2dBμV/m at 3m in frequency 49.860MHz, thus; The EIRP = [(FS*D) ^2*1000 / 30] = 0.00079mW Thus; Conducted power = Radiated Power (EIRP) – Antenna Gain So; Conducted Power = 0.0079mW. The SAR Exclusion Threshold Level for 49.860MHz when the minimum test separation distance is < 50mm: = [474 * (1 + log100/f(MHz))]/2 = 308.6mW 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.

Ltd. BRAND NAME: N/A, MODEL: CEC#51907 FCC ID: QKX0017049TX TEST SPECIFICATION REFERENCE RESULTS Transmitter Field Strength and Bandwidth Requirement 15.235 Pass The equipment under test is found to be complying with the following standards: FCC Part 15, October 1, 2011 Edition Note: 1. The EUT uses a permanently attached antenna which, in accordance to section 15.203, is considered sufficient to comply with the pervisions of this section. 2. Pursuant to FCC part 15 Section 15.215(c), the 20 dB bandwidth of the emission was contained within the frequency band designated (mentioned as above) which the EUT operated. The effects, if any, from frequency sweeping, frequency hopping, other modulation techniques and frequency stability over excepted variations in temperature and supply voltage were considered.
