How to Use

1. Clear a Channel

Select your channel using the "+" and "−" buttons. Press the two top-row buttons simultaneously and hold for 2 seconds until the LED flashes rapidly. Once flashing, release. Press any button — if the LED flashes and turns off, the clear was successful.

2. Copy a Remote

Select your desired channel. Hold your original remote next to the duplicator. Simultaneously press the matching button on both remotes and hold for approximately 3 seconds. When the channel number on the display stays lit (not flashing), the copy is successful. Repeat for additional buttons or channels as needed.

Note: Do not release the buttons until the display number stays solid — this confirms a successful copy.

3. Restore Last Saved Codes

Accidentally cleared your codes? Press the two middle-row buttons simultaneously for 2 seconds. The LED will flash, indicating the restore is complete. Press any button to confirm — keys should remain lit.

4. Lock a Channel

Select the channel, then simultaneously press the second button in the top row and the first button in the middle row. When the LED blinks rapidly, the channel is locked. Repeat to unlock.
