POWERFUL REPLACEMENT: The four buttons can copy four different types of chips, that is, one remote control can operate four different types of facilities. More than ten frequency points ranging from 270MHz to 434MHZ. Copying data is fast, not easy to lose code, and far away. MUCH SAFER, ENCRYPTED DESIGN: Strong privacy, one to one key copy, each key password will save alone. SLIDE-LOCK PROTECTIVE COVER: Comes with a slideable lid to protect the keys from dust and damage for longer service time. The small, compact and lightweight remote also features a cover that slides over the buttons to keep you from accidently pressing them in your pocket. WIDE RANGE OF APPLICATIONS: for cars, garage doors, doors, skylights, home security products, short-range wireless remote control products, electrical / home automation lights, industrial control products. Specification: Weight: 30g Frequency: 433MHZ Size: 54.5x29.5x13.8mm Chip that can be copied: 2260 (all manufacturers), 2262 (all manufacturers), PT2264, 5326 (all manufacturers), SC5262, HT600, HT680, HT6207, HT6010, HT6012, HT6014, SMC918 series, 527 (all manufacturers), 1527 (all manufacturers), 2240 (all manufacturers), HCS101, HCS200 HCS201 Clearing method: Press and hold "A" key and "B" key at the same time, the LED indicator will flash three times. Release any key that has been pressed, and the other one will not be loosened. Click the released key three times, and the LED indicator will flash rapidly. At this time, all the data in the memory will be cleared. After the data is cleared, no matter which key is pressed, the LED indicator will not light up. Copying method: One is to hold the original remote control, the other is to hold the copy remote control. The two remote controls should be as close as possible (ideally, the two remote controls should be placed close to each other on the desktop at zero distance). Press the buttons required for copying respectively. The LED indicator lights flash quickly for three times and then flash quickly. Copying is successful. The operation method of other buttons is the same. Some remote controllers have low transmission power, so the original remote controller and the copy remote controller should be operated back-to-back to copy each other. If there is interference in some operating environments, the interference operation should be avoided. If the copy is not easy, the copy should be repeated after the code is cleared. (Especially important: the remote control on your hand must work normally and have the same frequency as our remote control)
