Function Description
(1) Copy code operation
If the remote control has checked the code, the code must be cleared before the code can be checked. Code matching operation: press the single button of the copied remote control and the copy remote control at the same time, until the indicator of the copy remote control flashes from fast to steady on, you can release the two remote control buttons, and the code matching is successful. The other keys are also operated in sequence according to this method until all keys are copied.
(2) Clear code operation
Press and hold the lock and unlock buttons of the copy remote control at the same time until the indicator light flashes 3 times, and then short press the unlock button three times. The indicator light flashes continuously to indicate the success of the code clearing (the lock button is kept pressed during 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 light flashes quickly, you can restore the remote control code that was cleared before.
Notice:The remote control can not copy with the Rolling codes
Precautions
(1) The working voltage cannot exceed the normal working voltage by 1V.
(2) In an environment with relatively large wireless interference, the transmission distance may be reduced.
(3) Keep it out of reach of children.
(4) Do not use it in a humid environment, otherwise it may cause damage to the remote control
