How to Use

Clearing a Channel

Press buttons 1 and 2 simultaneously and hold for 2 seconds until the LED flashes. Keep holding until the LED flashes — only release when the light is flashing. After clearing, press any key on the remote; the LED will flash and go out to confirm the clear was successful.

Copying a Remote Code

Point your old remote at this duplicator and press the corresponding button on both devices simultaneously. Hold until the channel number on the display stays continuously lit — this confirms a successful copy. Repeat for each additional button/channel. Do not release either remote's button until the display confirms the copy.

Restoring a Code

If a code is accidentally cleared, press the two bottom keys on the duplicator simultaneously and hold for 2 seconds until the LED flashes rapidly. Release and then press the relevant remote button — if the display stays lit, the code has been successfully restored.

Channel Locking

To lock a channel and prevent accidental changes, press the second button in the first row and the first button in the middle row simultaneously. A rapid LED flash confirms the channel is locked. Repeat the same action to unlock.
