Em ission circuit description The remote control section is powered by 2 AA batteries that transmit the signal through the RF 2.4G. RF. The oscillator circuit includes X crystal oscillator (16MHz) and so on. The RF antenna transmission circuit includes L1 and A ntenna and so on, the LED lamp circuit is composed of R2 and LED, front and rear control circuit by the button K1 and K2 are made up of. Si gnal transmission process: Press the button, K1~K7, K9, K10 f unction has forward, backward, left slide , ri ght slide , le ft drift, right drift , de monstrate and other operation panel all the marking actions and functions. When the button is pressed, the RF passes through the X crystal oscillator circuit, and the signal passes through the IC Large modulation. After the filtering process, the ventilation antenna transfers the signal Frequency Range. 2405-2479MHz Channel List: Channel Frequency (MHz) Channel Frequency (MHz) 0 2405 17 2456 2 2406 18 2457 3 2422 19 2458 4 2424 20 2459 5 2425 21 2467 6 2426 22 2468 7 2427 23 2469 8 2428 24 2470 9 2436 25 2471 10 2437 26 2472 11 2444 27 2473 12 2445 28 2474 13 2446 29 2476 14 2447 30 2477 15 2449 31 2479 16 2451
