4.1. Learning Transmitter's Codes

  1. Press the "LEARN1" or "LEARN2" button on the receiver board for 1 second. The "learn_led" light on the receiver will illuminate.
  2. While the "learn_led" is lit, press the desired button on your FD020 remote control.
  3. Continue pressing the remote button until the "learn_led" flashes and then goes out. This indicates that the transmitter's code has been successfully stored.
  4. Repeat the above steps for any other FD020 remote controls you wish to program.

4.2. Erasing Transmitter's Codes

  1. Press and hold either the "LEARN1" or "LEARN2" button on the receiver board.
  2. Continue holding the button until the "learn_led" light goes out. This action will erase all codes of transmitters that had been stored on that channel.

5. Operation

Once programmed, operating your garage door or gate is straightforward:

  • Press the corresponding button on your FD020 remote control that you programmed for your garage door or gate.
  • The door/gate should activate (open, close, or stop) according to your system's configuration.

6. Maintenance

6.1. Battery Replacement

The remote control is powered by an internal battery. If the remote's range decreases significantly or it stops responding, the battery may need replacement. To replace the battery:

  1. Carefully open the remote control casing. This may involve removing a small screw on the back or prying open the seam with a small tool.
  2. Note the type and orientation of the existing battery (typically a coin cell battery).
  3. Remove the old battery and insert a new one of the same type, ensuring correct polarity.
  4. Close the remote control casing securely.

6.2. Cleaning

Wipe the remote control with a soft, dry cloth. Avoid using harsh chemicals or abrasive cleaners, as these can damage the casing or internal components.

7. Troubleshooting

  • Remote not working after programming: Ensure the programming steps were followed precisely. Try erasing all codes and reprogramming. Check the remote's battery.
  • Limited range: Replace the remote's battery. Ensure the receiver's antenna is unobstructed and properly positioned. Large metal objects or other radio frequency interference can reduce range.
  • Door/gate opens/closes unexpectedly: This could indicate interference or an issue with the receiver. Try erasing all codes and reprogramming only your remotes.
