How to Clone Your Original Remote
- Place both remotes back-to-back, ensuring direct contact.
- Hold down one button on your original remote and the corresponding button on the duplicator simultaneously — keep holding until the LED blinks twice.

- Tip: If cloning stalls at 2 blinks, slowly shift the remotes up or down to find the optimal signal transfer point.
