Specification: Material: ABS Type: AB, ON/OFF, Close Unlock Product size: 50*35*12mm / 1.96*1.37*0.47 inches Rated voltage: 12 V Rated current: 10 mA Installation mode: Wireless Corresponding frequency: 433 MHz Modulation mode: ASK (AM) Wireless transmission distance: 50-100m (open space) Application: Garage door, alarm, automatic door, rolling door, etc. Compatible chip types: 2260 (e.g. PT2260, SC2260, LX2260, HX2260); 2262 (e.g. PT2262, SC2262, LX2262, HS2262, HX2262); PT2264, PT2240 (LX2240), 1527 (e.g. EV1527, HS1527, HX1527), FP527, CS5211, SMC918, SMC926, AX5026, AX5326-3, AX5326-4, HT600, HT680, HT6207, HT6010, HT6012, HT6013, HT6014, HT12D, HT46F49E, PIC16F629, PIC16F630, and other compatible chip models. Chips with matching model numbers can be copied. Note: Rolling code chips are not recommended for copying due to uncertainty in the process. It is not possible to determine if the original remote uses an encrypted chip. Copying rolling code remotes with a paired remote is not advised. Operation Manual: 1. Clear Code: Press and hold both lock buttons simultaneously until the LED flashes three times. Release one button while keeping the other pressed, then press the release button three times. When the LED starts flashing rapidly, all stored data is cleared. After clearing, pressing any button will light up the LED indicator. 2. Copy: Hold the original remote and the copy remote close together, ideally side by side with no distance between them. Press the corresponding buttons on both remotes at the same time. After three quick flashes of the LED, the copy is successful. Repeat for other buttons. For remotes with low transmission power, position them back-to-back for better signal. Avoid areas with interference. If copying fails, clear the code and try again. 3. Restore: If the code is accidentally cleared, press and hold both bottom buttons on the copy remote. After three flashes, release. Then press any button; if the LED stays on, the remote has been restored to default settings. Always clear existing codes before starting a new copy process. 4. Partial Key Copy Issue: If only some buttons work after copying, follow these steps: (1) Clear the code. (2) Copy only the buttons that were not previously copied, avoiding re-copying already successful ones. (3) Clear the code again. (4) Perform a restore operation. This retains previously copied buttons while updating the missing ones. Repeat the process if necessary until all buttons function correctly. Warm Tips: 1. Ensure the original remote is functional, uses a compatible chip, and operates at the same frequency. 2. The copy remote only supports fixed code, learning code chips, and certain single-chip remotes (as listed above).
