Remote control dinosaur car function line description: 1. The remote control uses two 1.5V AAA batteries for powersupply. The dinosaur car is powered by 4 1.5V AAAbatteries. 2. After the remote controller is installed with battery and powered on, the LED1 light flashes to indicate the status of code matching. At this time, the IC1 will automatically transmit an encoded signal, which is formed by C1, and C2 to form an LC filter wave and transmit it through the TX antenna. 3. The remote control does not enter the dormant state if it does not match the code within 30 seconds, and it enters the dormant state if it does not press K1 or K2 within 30 seconds after the code is coded. Press K1 or K2 at will to wake itup. 4. The OFF position turns off all functions and disconnects the powersupply. Frequency List Channel Frequency (MHz) 1 2404.8 2 2432.8 3 2464.8
