When the light is turning dimmer and dimmer, the batteries are to be replaced; (3)Operate the handle of the controller, the car can move forward/backward, roll left/right or stop. The body-light can also light. (4)After play, turn the power switches to “OFF” position. NOTE: THE MANUFACTURER IS NOT RESPONSIBLE FOR ANY RADIO OR TV INTERFERENCE CAUSED BY UNAUTHORIZED MODIFICATIONS TO THIS EQUIPMENT. SUCH MODIFICATIONS COULD VOID THE USER AUTHORITY TO OPERATE THE EQUIPMENT.

Transmitter: When press the control key forward/backward/right-ward/left-ward, the instruction were input to the coding circuit; The coded signal is amplified together with high frequency vibration signal; After LC filter, the signal is transmit by the antenna. Receiver: High frequency signal passes the antenna and enter the decoding circuit; After decoding, output action signal(+5V); The action signal voltage is amplified and drive the motors running individually. Instruction Coding circuit Quatz vibrating circuit antenna LC filter Amplifying circuit antenna High frequency signal Amplifying circuit Decoding circuit Turning drive circuit OTL Amplifying circuit Forward/backward drive circuit

FCC ID Label Sample FCC ID: TB7DXTOYS55949 This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

Operation Description Transmitter: When press the control key forward/backward/right-ward/left-ward, the instruction were input to the coding circuit; The coded signal is amplified together with high frequency vibration signal; After LC filter, the signal istransmit by the antenna. Receiver: High frequency signal passes the antenna and enter the decoding circuit; After decoding, output action signal(+5V); The action signal voltage is amplified and drive the motors running individually.

CIRCUIT DESCRIPTION TRANSMIT Part: TX-2: IC1 is a 4 functional remote encoder IC. it’s work with transistor Q1, Q2 and other components combined as RF transmitter circuit. The IC Pin 1, 14, 4 and 6 control left, right, backward, forward and encoding signal output respectively. Data output from Pin 8 and modulate with 49MHz oscillator that achieved by Q2, Y1, R2, R3, L3and C3. RF power amplifier Q1, L1,L2, C1, C2 are used to enlarge the transmission range. ANTENNA GROUND CIRCUITRY This unit makes use of an external 20-inch rod antenna, the antenna is inductively coupled, the unit relies on the Ground trace of the circuit board. A 9V alkaline battery supplies energy.
