To perform code matching: Press and hold a button on both the original remote control and the copy remote control simultaneously until the indicator light on the copy remote changes from flashing quickly to a steady light, then release both buttons. Code copying is successful. Repeat this process for each button until all desired functions are copied. 2.

While continuing to hold the lock button, briefly press the unlock button three times to clear the stored code. 3. Restore Previously Cleared Code: Press and hold the silent and ring buttons on the copy remote control simultaneously until the indicator light flashes rapidly.
