Self-learning remote control clone /copy /duplicate your old remotes controls .Now you don't need to be worry about lost or how to replace your old remote control .just tell me the frequency of your original remote control .the common frequency is 315MHZ OR 43MHZ .and then you can get a remote control that can copy /clone /duplicate your original or old remote control.it can clone/copy/duplicate most of the fixed code /learning code remote controls .such as2260， 2262， FP527， HT12D ， HT12E ， PT2240， S026-1 ，S026-2 ，S026-3 ，S026-4， SMC918.... etcPlease pay attention to it doesn't clone/copy the rolling code .such as the IC is HSC301 201I . Technical parametersOperating voltage: DC12VOperating current: 10MAFrequency available: Fixed frequency 315/433.92MHz (We can do customized frequency)Adjustable frequency:290MHz-480MHzAmbient temperature : -20 'c ~ +50'c Easy duplication of :Car alarm remotes.Motorbike alarm remotes.House alarm remotes.Garage / shed alarm remotes.Vehicle central locking system remotes.Electric garage door remotes.Auto gate remotes.Electric gate remotes.Home automation device remotes - ie. Remote sockets，Lights etc. Methods of operation1， Clear out code:To Clear up test stored rf signal memory from factory by pressing the locking key and unlock the key at the same time， two seconds later， LED indicator light flashes three times， then loosen one finger and press 3 times within 3S ，followed by a continuous fast blinking. Indicates that the remote control codes stored has been cleared out.2， Duplicating (learning)Hands are holding remote control ， and the other are holding the duplicating remote control， 2 remote controls put together as close as possible， while pressing the remote controls two match button，(eg: A-A，B-B) three seconds later， LED indicator light flashes three times， followed by a continuous fast blinking. This indicates that this copy of the remote control buttons are same as copied on the remote control button codes . Several other keys are also according to the above approach to learning.3， Recovery codeIf the code copied have been mistakenly removed the remote control， you do not worry， the remote control can restore yourself. Method is pressing (up-down eg: locking key and bell key) two buttons (metal shell remote control on the left， the plastic shell remote control on the right) at the same time ，3 seconds later， LED indicator light flashes three times， followed by a continuous fast blinking. This indicates that the original remote control codes have been restored.The other way， you can delete all and relearn them again
