Step 1 Clearing method: Press the "A" button and the "B" button at the same time, the LED indicator flashes three times, release the pressed "B" button, the "A" button remains pressed, click the released "B" button three times, LED indicator enters the fast flashing state. At this time, the memory data is completely cleared. After the data is cleared, the LED indicator remains off regardless of button presses. Step 2 Copy method: One hand holds the original remote control, the other holds the new remote control, and the two remotes are placed as close as possible. (ideally, place both remotes side by side on a flat surface with zero distance between them.) Press the desired button. The LED indicator flashes rapidly after three initial flashes, indicating successful copy. Repeat the same process for other buttons. Some remote controls have low transmission power and should be operated back-to-back with the original remote. Avoid operations in environments with signal interference. If copying fails, clear the memory and retry. Note: The original remote control must be functional and operate on the same frequency as the new remote. New remote control features: Four buttons can copy four different chip types, allowing one remote to operate four different devices. Frequency range: 270MHz to 434MHz with support for multiple frequency points. Fast data copying, reliable code retention, and extended operating distance.
