Chips could be copied: 2260(all manufacturers);2262(All manufacturers);PT2264, 5326(All manufacturers);SC5262, HT600, HT680, HT6207, HT6010, HT6012, HT6014, SMC918series,527(All manufacturers);1527(All manufacturers);2240(All manufacturers);HCS101, HCS200/HCS201(part code),HCS300/HCS301 (part code), part single chip microcomputer.......... Code cleaning method: Press the unlock button and lock button at the same time(some shells are the up button and down button), after the LED indicator light flashes three times, loosen any one of the buttons while the other is kept pressing, then push the released button three times the LED indicator will enter into the fast flashing status. At this time all the memory data is cleared, the cleaned remote control will not have lighting LED indicator no matter which button you press. The four buttons could respectively copy four different types of chips, That is a remote control can operate four different types of facilities. T Faster copy data speed, not easy losing code, far distance. Copy method: One hand keeps the old remote controller, while another keeps the copy remote control, the two remote controls should be placed as closely as possible (the ideal situation is to put the two remote controls on the desktop side by side with zero distance), respectively press down the copy button when the LED indicator light flashes quickly after three flashes, this copy is successful, other key operating methods are the same. Some remote control has a smaller mitting power, so the old remote control should be placed back to the copy remote control to be operated. For the presence of noise it should avoid interference to operate, If the copy is not successful, it should recopy after clearing code.( Attention:Your remote control must be able to work and the same as our remote control frequency Colour:As Shown Material:plastic Package Contents: 1 x Gate Door Opener <br /
