3. Initial Setup
The remote control comes with a pre-installed button battery (2032). No complex assembly is required. Before copying, ensure the remote control is cleared of any previous codes.
4. Operating Instructions
The MOJOYCE clone remote control supports clearing, copying, and recovering codes. Follow the steps below carefully.
Video 1: Demonstration of Clear Code and Copy Code Operations
4.1. Clear Code Operation
If the remote control has been previously programmed, it is necessary to clear the existing code before matching a new one. This ensures a clean slate for copying.
- Press and hold both the Off Lock (usually the top-right button) and On Lock (usually the top-left button) buttons simultaneously.
- Continue holding until the indicator light on the remote control flashes rapidly.
- While still holding the Off Lock button, release the On Lock button.
- Press the On Lock button three times.
- The indicator light will flash quickly, indicating that the code has been successfully cleared.
4.2. Copy-to-Code Operation
This process allows you to duplicate the signal from an existing remote control to your MOJOYCE clone remote.
- Ensure the clone remote control has been cleared (see Section 4.1).
- Place the original remote control and the clone remote control close to each other.
- Simultaneously press a single button on the original remote control and the corresponding button on the clone remote control.
- Continue holding both buttons until the indicator light on the clone remote control changes from a slow flash to a rapid, steady flash.
- Release both buttons. The code matching for that button is successful.
- Repeat this process for all other buttons you wish to copy.

4.3. Recovery Code Operation
If you accidentally clear the code or wish to revert to a previously copied code, you can use the recovery function.
- Press and hold both the Mute (usually the bottom-left button) and Ring (usually the bottom-right button) buttons simultaneously.
- Continue holding until the indicator light flashes rapidly.
- Release both buttons. The previously cleared remote control code will be restored.
5. Maintenance
5.1. General Care
- Keep the remote control clean by wiping it with a soft, dry cloth.
- Avoid exposing the remote control to extreme temperatures or direct sunlight for prolonged periods.
- Do not drop or subject the remote control to strong impacts.
5.2. Battery Replacement
The remote control uses a DC3V button battery (2032). If the remote control's range decreases significantly or the indicator light does not illuminate, it may be time to replace the battery. To replace:
- Carefully open the remote control casing.
- Remove the old 2032 button battery.
- Insert a new 2032 button battery, ensuring correct polarity.
- Close the casing securely.
6. Troubleshooting
Common Issues and Solutions:
- Remote not copying: Ensure the clone remote is cleared before attempting to copy. Make sure both remotes are very close during the copying process. Verify that the original remote is transmitting a strong signal.
- Short transmission distance: Check the battery level and replace if necessary. Ensure there are no significant obstructions or sources of wireless interference between the remote and the receiver.
- Indicator light not flashing: Check the battery. If the battery is new and correctly installed, the remote may be faulty.
- Copied code not working: Ensure the original remote's frequency (315 MHz or 433 MHz) matches the clone remote's frequency. Some rolling code remotes or encrypted remotes cannot be copied by this universal duplicator.
7. User Tips
- Verify Frequency: Before purchasing or attempting to copy, it is crucial to know the operating frequency of your existing remote control (e.g., 315 MHz or 433 MHz) to ensure compatibility with this duplicator.
- Optimal Copying Distance: For best results during the copy-to-code operation, place the original and clone remotes as close as possible, ideally touching.
- Test All Buttons: After copying, test each button on the clone remote to ensure all desired functions have been successfully transferred.
8. Safety Warnings and Notes
- The working voltage should not exceed the normal working voltage by 1V.
- In an environment with high wireless interference, the transmitting distance may be reduced.
- Keep out of reach of children.
- Use in a humid environment is prohibited, otherwise it may cause damage to the remote control.
