1. Chips can be copied 2260(all manufacturers);manufacturers);1527(All manufacturers);2240(All manufacturers);HCS101, HCS200HCS201(part code),HCS300HCS301 (part code), part of single chip microcomputer. 2. Code clearing method: At the same time, press and hold the two keys of unlock and lock (some cases have up and down two keys), the LED indicator flashes three times, release one of the pressed keys,the other is not released, click the released key three times, the LED indicator enters a rapid flashing state, at this time, all the memory data is cleared, after the remote control data is cleared, whichever key is pressed, the LED indicator is not lit. 3. Copy method: One hand holding the original remote control, the other hand holding the copied remote control, the two remote controls as close as possible, respectively, press the required copy of the button, the LED indicator flashes three times quickly after thefast flashing, copy is successful, buttons work the same.As the transmitter power of some remote controls is low, the original remote control and the copied remote control must work back to back, only a good copy is possible.If the copy is not very good, you must copy again after erasing the code.(Particularly important: your remote control must work correctly and have the same frequency as our remote control). 4. Features of the new copy remote control: Four buttons can copy four different types of chips, that is, one remote control can operate four different types of facilities.Frequency of 270MHz~434MHZ and so on, more than ten frequency points.The data copy speed is faster, there is no risk of code loss, and the distance is far. 5, you can copy common garage door, telescopic door, road barriers, car locks, anti-theft device brands.
