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. _x005f_x000D_ (2) Code clearing operation _x005f_x000D_ 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). _x005f_x000D_ (3) Recovery code operation _x005f_x000D_ 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. _x005f_x000D_ _x005f_x000D_ Attention: _x005f_x000D_ (1) The working voltage shall not exceed 1V of the normal working voltage. _x005f_x000D_ (2) In the environment with large wireless interference, the transmission distance may be reduced. _x005f_x000D_ (3) Keep out of the reach of children. _x005f_x000D_ (4) Do not use it in a humid environment, otherwise it may cause damage to the remote control. _x005f_x000D_ _x005f_x000D_ Note: _x005f_x000D_ Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you! _x005f_x000D_ Please allow 1-2cm measuring deviation due to manual measurement. _x005f_x000D_ _x005f_x000D_ Included: _x005f_x000D_ 1 x Copy Duplicator  _x005f_x000D_ Rubber keys.
