1. Introduction
This manual provides comprehensive instructions for the DOACT 4-in-1 433MHz Universal Clone Fob Remote Control Duplicator. This device is designed for one-to-one key copying, allowing each key password to be saved separately for ease of use. It supports multiple copies in a row and is particularly suitable for home remote control duplication. The remote is compatible with a wide range of remote control codes within 80 bits.
Compatible Codes: 2262, 2260, 5026, 5326, 5326-3, FP527, PT2240, EV1527, HT6014, HT12E, HT640, HT680, PLC168, 9XX series, PT2292, 12L-4SC, HT6026, UM3750AM, and similar remote control types.

2. Setup and Programming
Follow these steps carefully to clear existing codes and copy new ones to your remote control duplicator.
2.1. Clear Existing Code
- Press and Hold Buttons: Simultaneously press and hold the front two buttons (often labeled 'A' and 'B', or 'up/unlock' and 'down/lock' on some models) on the DOACT remote.
- LED Flash: The LED indicator will flash three times.
- Release and Press: Release one of the buttons (while keeping the other pressed). Then, press the released button three times.
- Fast Flashing: The LED indicator will enter a fast flashing state, indicating that the code has been cleared.
- Verification: After clearing, pressing any button on the remote should not illuminate the LED indicator. If it does, repeat the clearing process.

2.2. Copying a New Code
- Position Remotes: Place your original remote control and the DOACT duplicator remote close to each other, ideally with direct contact, to ensure optimal signal transfer.
- Press Original Button: Press and hold the desired button on your original remote.
- Press Duplicator Button: While still holding the original remote's button, press and hold the corresponding button on the DOACT remote where you wish to store the code.
- LED Confirmation: Continue holding both buttons until the LED indicator on the DOACT remote flashes quickly, then becomes solid. This signifies successful code copying.
- Repeat for Other Buttons: Repeat this process for any other buttons you wish to clone.
- Important Note: If the cloning process is not successful, try clearing the code again and repeating these steps. For remotes with lower transmission power, ensure they are very close and avoid interference.

2.3. Reinstating Erased Code
If you accidentally erase a code, you can recover it by following these steps:
- Press and Hold: Press and hold the 'C' and 'D' buttons (or equivalent buttons on other models) simultaneously for a prolonged period.
- LED Flash: When the LED flashes, the previously erased codes will be recovered.

3. Operating the Remote Control
Once programmed, your DOACT remote control duplicator functions identically to the original remote it copied. Simply press the corresponding button to activate the desired function (e.g., open/close a garage door, unlock a car).

4. Maintenance
- Cleaning: Wipe the remote with a soft, dry cloth. Avoid using harsh chemicals or abrasive cleaners.
- Battery: The remote operates on a DC12V battery. If the remote's range decreases or the LED indicator becomes dim, replace the battery. To replace, carefully open the remote casing (usually by prying gently with a small flat-head screwdriver) and insert a new DC12V battery, ensuring correct polarity.
- Storage: Store the remote in a dry place, away from extreme temperatures and direct sunlight.
5. Troubleshooting
- Remote Not Programming:
- Ensure the original remote is functioning correctly.
- Verify that the DOACT remote's code has been completely cleared before attempting to copy.
- Place the original and duplicator remotes as close as possible, even touching, during the copying process.
- Try different angles or positions for the remotes during copying to ensure optimal signal reception.
- Some original remotes may have lower transmission power, requiring closer proximity.
- Copied Code Not Working:
- Re-attempt the copying process, ensuring the LED flashes quickly and then becomes solid.
- Confirm that your original remote's frequency (433.92MHz for this model) is compatible with the DOACT duplicator.
- LED Indicator Not Lighting Up:
- Check the battery. Replace if necessary.
- If the code was cleared, the LED will not light up until a new code is successfully copied.
