RV3-04054-RX49R/C DOLPHIN

Operation Description The R/C Dolphin is powered by 1 X 9V battery for Tx, 1 X 3.6V rechargeable battery for Rx and 6 X 1.5V ìAAî size battery for charger. There are 5 control buttons in the front of unit. When the Dive up, Dive down, Forward, Turn Left, and Turn Right button pressed once, it will transmit a difference radio signal for receiver moving difference direction. Refer to the receiver circuit design, the circuit description is listed as below: For Tx
U1 and associate circuit act as encoder.
X1, Q1 and associate circuit act as oscillator.
Q2 and associate circuit act as mixer and amplifier For Rx
Q1 and associate circuit act as Super- Rege.
Q2, U2 and associate circuit act as decoder.
Q12, Q13, Q5~Q10, Q17~Q22 and associate circuit act as motor drive circuit.
U1 and associate circuit act as voltage control IC.
