4. Function description
(1) Copy-to-code operation
If the remote control has been used for the code, it is necessary to clear the code before the code can be matched. Code matching operation: press the single button of the remote control being copied and the copy remote control at the same time, until the indicator of the copy remote control flashes from fast to bright, then release the two remote control buttons, the code matching is successful. Follow this method for other keys until all keys are copied.
(2) Clear code operation
Press and hold both the Off Lock and On Lock buttons at the same time until the indicator light flashes, then press the On Lock button three times to clear the code (keep the Off Lock button pressed during this process).
(3) Recovery code operation
Press and hold the Mute and Ring buttons at the same time until the indicator light flashes, then you can restore the previously cleared remote control code.

5. Notes
(1) The working voltage should not exceed the normal working voltage by 1V.
(2) In an environment with high wireless interference, the transmitting distance may be reduced.
(3) Keep out of reach of children.
(4) Use in a humid environment is prohibited, otherwise it may cause damage to the remote control.
