Setup and Programming Instructions
Follow these steps to program your new remote control duplicator:
Step 1: Clear the History Code from the Duplicator
- Press and hold buttons A and B simultaneously on the duplicator until the LED flashes 3 times.
- Release button B (while continuing to hold button A).
- Press button B slowly 3 times. The LED will flash 3 times again.
- Release button A. The code clearance is now complete.
Step 2: Copy Code from the Original Transmitter
- Place the duplicator and your original transmitter side-by-side, as close as possible.
- Press and hold button A on your original transmitter.
- While still holding button A on the original transmitter, press and hold button A on the duplicator. Continue holding both until the duplicator's LED flashes.
- Release both buttons. The code for button A is now copied.
- Repeat the process for other buttons (B, C, D) if desired, using the corresponding buttons on both the original and duplicator remotes.
Note: Button A typically functions as the Lock button, and Button B as the Unlock button, but this can vary based on the original remote's configuration.

Maintenance
The remote control duplicator is powered by a 12V 27A battery. When the remote's range decreases or the LED indicator becomes dim, it may be time to replace the battery. To replace the battery, carefully open the remote casing and insert a new 12V 27A battery, ensuring correct polarity.
Troubleshooting
- Remote not copying: Ensure the original remote is a fixed code or learning code type operating at 433.92MHz. Place the duplicator and original remote as close as possible during the copying process. Make sure the duplicator's battery is not low.
- Short transmission range: Check the battery level of the duplicator. Replace if necessary. Ensure there are no significant obstructions between the remote and the receiver.
- LED not flashing: If the LED does not flash during programming, ensure buttons are pressed firmly and held for the required duration. The battery might be depleted.
User Tips
- Always clear the duplicator's memory before attempting to copy a new remote to prevent interference from previous codes.
- For best results during copying, ensure both remotes are in close proximity and held steady.
- Test the copied remote immediately after programming to confirm functionality.
