Function:
(1) Copy code operation
If the remote control is over code, you need to clear the code to correct the code. Code matching operation: press the single key of the copied remote controller and the copied remote controller at the same time until the indicator light of the copied remote controller flashes from fast to constant, then release the two remote controller keys, and the code matching is successful. Other keys are also operated in this way until all keys are copied.
(2) Code clearing operation
Press and hold the lock off and unlock keys of the copy remote control at the same time until the indicator flashes for 3 times, and then briefly press the unlock key for 3 times. The continuous flash of the indicator indicates that the code clearing is successful (the lock off key is pressed all the time in this process).
(3) Recovery code operation
Press and hold the mute and ring buttons of the copy remote control at the same time until the indicator flashes, and the previously cleared remote control code can be restored.

Attention:
(1) The working voltage shall not exceed 1V of the normal working voltage.
(2) In the environment with large wireless interference, the transmission distance may be reduced.
(3) Keep out of the reach of children.
(4) Do not use it in a humid environment, otherwise it may cause damage to the remote control.
