[Fixed Frequency Remote Cloning]: This is a fixed-frequency remote cloner (433.92 MHz) designed to copy most common fixed-code and learning-code remote controls. [Safe and Easy to Use]: Simple 4-channel remote control system with anti-theft functionality. Suitable for controlling vehicles, homes, garages, and other compatible devices. Operating range: 50–100 meters in open environments. [Wide Application]: Compatible with automobiles, garage doors, gates, skylights, vehicle alarms, home security systems, short-range wireless remote devices, household appliances, lighting, and industrial control equipment. Clearing Method: Press and hold both “A” and “B” buttons simultaneously until the LED flashes three times. Release only the “B” button while continuing to hold “A”, then press “B” three times. The LED will flash rapidly, indicating all stored data has been erased. After clearing, pressing any button will not activate the LED. Copying Method: Hold the original remote and the cloning remote close together—ideally back-to-back for low-power remotes. The LED will flash three times quickly, then rapidly flash again when copying is successful. Repeat for each button. If interference occurs, relocate to a less congested area. If copying fails, clear memory and retry. Color: Black Material: ABS + Metal Package Contents: 1 x Remote Cloner
