How to Use
Step 1 — Clear Existing Codes
Press and hold the two top buttons simultaneously. Keep holding until the LED flashes briefly and then goes out. After 2 seconds, the LED will begin flashing again, confirming the codes have been cleared. To verify: press any button — if the LED flashes once and immediately turns off, the clear was successful.
Step 2 — Copy Your Remote
Hold your original remote in your left hand and the duplicator in your right. Bring them as close together as possible. Press the corresponding button on both remotes at the same time. The LED on the duplicator will flash continuously, indicating the code from your original remote has been successfully learned. Repeat for each of the remaining 3 buttons.
Step 3 — Restore Saved Codes
If codes are accidentally cleared, press and hold the two bottom buttons simultaneously. After 3 seconds, the LED will light up and then flash quickly, confirming that your previously stored codes have been restored.
