OPMHC20026002Radio Control Toys - Turbo Twister

Operation Description of transmitter for Radio Control Toys ñ Turbo Twister Tx The Turbo Twister Tx is a transmitter operating at 49.860 MHz which is controlled by a crystal. It is powered by 9V battery. There are two control sticks on the front side of the transmitter. When the left and right control stick is pushed once, it will transmit a radio frequency for receiver forward, backward, turn left and turn right. Refer to the circuit design, the circuit description is listed as follows: - X1 and associated circuit act as oscillator - Q2 and associated circuit act as amplifier - IC1 and associated circuit act as encoder

The EUT is powered by 9 V battery. There are two control sticks on the front side of the transmitter. When the left and right control stick is pushed once, it will transmit a radio frequency for receiver forward, backward, turn left and turn right. The brief circuit description is listed as follows : - X1 and associated circuit act as oscillator - Q2 and associated circuit act as amplifier - IC1 and associated circuit act as encoder Models 0986 and 0987 are the same as model 0980 in circuitry and components. The difference in these three models are plastic bodies only. 1.2 Related Submittal Grants This is a single application for certification of a transmitter. The receiver for this transmitter is authorized by Certification procedure.
