Step 1 Clear the methodPress the A button and the B button at the same time, the LED indicator flashes three times, release the pressed B button,The A button is not loose, click the released B button three times, the LED indicator light enters the fast flashing state. At this time,the memory data is completely erased. Once the data has been erased, the LED indicator will not light up regardless of which button is pressed.Step 2 Copy the methodOne hand holds the original remote control, the other holds the remote control, and the two remote controls are as close as possible.Ideally, the two remote controls are placed on the desk with the zero distance on the side. Press the desired button.The LED indicator will flash quickly after three flashes and the copy is successful. The other buttons work in the same way.Some remote controls have a small transmission power and they should be operated back to back with the original remote control and the remote control.Some operating environments have interference and should avoid the interference operation. If the copy is not good, copy it again after clearing the code.It is especially important that the remote control on your hand must work correctly and have the same frequency as our remote controlNew copy remote control functionsFour buttons can be used to copy four different types of chips, meaning one remote control can control four different types of facilities.The frequency ranges from 270MHz to 434MHZ and more than ten frequency points. Data copying is faster, it is not easy to lose the code, and the distance is long.Material ABSelectronic componentsCompatible chips 2260, 2262, PT2264, 5326, SC5262, HT600, HT680, HT6207, HT6010, HT6012, HT6014, SMC918, 527, 1527, 2240, HCS101, HCS200HCS201, HCS300HCS301, etc.Compatible crystal frequency 315MHz433MHzEffect 127A battery includedThe package contains1 remote control copier
