OPMHC20023006Radio Control Toys

Operation Description of transmitter for remote control toy car The transmitter for remote control toy car is operating at 27.145 MHz which is controlled by a crystal. It is powered a 9V battery. There is an ON/OFF switch, a pair of control levers on its left and right side to control the forward as well as backward moving and circular path respectively. It also has a button on the right side featuring a jumping function. Refer to the circuit design, the circuit description is listed as follows : - IC1 and associated circuit act as encoding - Q1 and associated circuit act as modulation - X1, Q2 and associated circuit act as oscillation and amplification

Report No. : AC002828 Date : 2002 March 19 1 General Information The equipment under test (EUT) is a transmitter for remote control toy car operating at 27.145 MHz which is controlled by a crystal. The EUT is powered a 9V battery. The EUT has an ON/OFF switch, a pair of control levers on its left and right side to control the forward as well as backward moving and circular path respectively. It also has a button on the right side featuring a jumping function. The brief circuit description is listed as follows : - IC1 and associated circuit act as encoding - Q1 and associated circuit act as modulation - X1, Q2 and associated circuit act as oscillation and amplification The models 3006, 3007, 3008, 3009, 3610, 8620, 8630, 8640 and 8650 are the same as model 3003 in hardware aspect. The difference in model numbers serves as marketing strategy. 1.1 General Description 1.2 Related Su…
