4. Function Description
(1) Copy Code Matching Operation
If the remote control has checked the code, it needs to be cleared before the code can be checked. Code matching operation: Press a single button on both the copied remote control and the copy remote control at the same time, until the copy remote control indicator light flashes from fast to steady, and then release the two remote control buttons. Code matching is successful. Follow this method to operate other buttons in sequence until all buttons are copied.

Simultaneously press and hold the lock and unlock buttons on the copy remote control until the indicator light flashes three times, and then briefly press the unlock button three times to indicate that the code has been cleared successfully (the lock button is held down continuously during this process).
(3) Recovery code operation
Press and hold the mute and ring buttons of the copy remote control simultaneously until the indicator light flashes quickly, and the previously cleared remote control code can be restored.
