IC Pin 3, 5, 2 and 1 control left, right, back, forward and encoding signal output respectively. The encoding data output from Pin 13 and modulate with 27.145MHz oscillator that achieved by Q1, Y1, R3, R6, C5 and L1. The RF power amplifier Q2, L2, C6, C7 are use to expansion transmission scope, the output frequency through LC filter C3, C4 and L3, elimination harmonic frequency that the signal which transmits by aerial E1. R/C receiver: Operation: 4.5V AA Size battery x 3pcs; Drawing Ref.: 1:24 Radio Control (RX); Super-regenerative receiver use a special type of detector, in a straight regenerative circuit, input signal couples to the detector, and some of the output signal feedback to its input, in phase. This repeatedly amplifies the input signal. The result is very high gain in a single stage. Q13 provides RF gain and helps prevent the receiver from radiating its signal out the antenna. The data signal obtained by detector then couples to Video Amplifier U1 (RX2C) pin 14 through the LPF circuit (R13, C7). The IC provides two high effective amplifiers and enhances signal input recognition capacity to enhance remote control distance. The data signal obtained by the U1 then couples to decoder IC U2 (RX2-3A) and The signal input to the decoding circuit by pin4, the control function through the pin 7, 6, 2, 3 to driving the motor circuit. 裕 豐 玩 具 實 業 有 限 公 司 Uni-Fortune Toys Industrial Limited 香港九龍荃灣沙咀道21-27號昌興盛中心21樓A-C室 FLAT A-C, 21/F., CHEUNG HING SHING CENTRE, TEL: (852) 2413 0983 21-27 SHA TSUI ROAD, TSUEN WAN, FAX: (852) 2414 4183 N.T., HONG KONG E-mail: [email protected] Specification of RC Vehicle Model No: 23854, 23864, 23874, 23884, 24184, 24194, 24204, 24214, 24224, 24234, 24244, 24254, 25954, 25964, 25974, 25984, 25994, 26004, 26014, 26034 Description: (Front, Back, Left, Right, Stop) Full function radio control car Radio Freq.: 27.145MHz ±30PPM at 25°C Control Range: Over 15m control radius from R/C transmitter at open site Transmitter: 9V (6F22 battery) Power Supply Receiver: 4.5V (R6P/ SIZE AA x 3 battery) Transmitter: 7V Min. operation voltage: Receiver: 3.6V Standby- 270mW approx.

It operates at 27.145MHz and the oscillation of radio control is generated by a crystal. The EUT is powered by 1 x 9V size battery. There are two control sticks on the EUT. When the control stick is triggered, the EUT will transmit radio control signal to the receiver. The antenna is using unique connector and the radio output power is unable to adjust. The brief circuit description is listed as follows: - U1 and its associated circuit act as an encoder. - D1 and its associated circuit act as a voltage regulator. - Q1, Y1 and its associated circuit act as an oscillator. - Q2 and its associated circuit act as a RF amplifier.
