3. Setup and Binding Instructions

To establish communication between your LICHIFIT 4100E receiver and a compatible DSM2 transmitter, follow these binding steps:

1. Connect the Bind Plug: Insert the bind plug into the "BIND" port on the receiver. Ensure the plug is fully seated and correctly oriented. The negative pin is typically the furthest from the board.

2. Power the Receiver: Connect a power source (e.g., battery or ESC with BEC) to any available channel port on the receiver. The receiver's LED should begin to flash rapidly, indicating it is in binding mode. If the LED only "blips" or does not flash, check the power connection and bind plug orientation. A steady LED indicates a successful connection, not binding mode.
3. Activate Transmitter Bind Mode: Turn on your compatible DSM2 transmitter while holding its bind button or activating its bind function (refer to your transmitter's manual for specific instructions).
4. Complete Binding: The receiver's LED should change from rapidly flashing to solid, indicating a successful bind.
5. Remove Bind Plug: Once the LED is solid, disconnect the power from the receiver, then remove the bind plug from the "BIND" port.
6. Test Connection: Reconnect power to the receiver (without the bind plug). The LED should illuminate solid, confirming the bind. Test all control surfaces and functions to ensure proper operation.

Note: Some users have reported that the receiver may require re-binding if the battery is disconnected for an extended period or if the power cycle is interrupted during initial setup. Always verify the solid LED indicator after powering on.

4. Operating Instructions

After successful binding, connect your servos and Electronic Speed Controller (ESC) to the corresponding channels on the receiver. The LICHIFIT 4100E provides 4 channels for various control functions.

• Channel Connections: Connect servos for ailerons, elevator, rudder, and the ESC for throttle control to the appropriate channel pins. Refer to your model's specific wiring diagram.
• Power On Sequence: Always turn on your transmitter first, then power on the receiver. When powering off, disconnect power from the receiver first, then turn off the transmitter.
• Range Check: Before flight or operation, perform a range check according to your transmitter's instructions to ensure a stable connection.

5. Maintenance

Proper maintenance ensures the longevity and reliable performance of your receiver.

• Keep Dry: The receiver is not water-resistant. Avoid exposure to moisture, humidity, and liquids.
• Cleanliness: Keep the receiver free from dust, dirt, and debris. Use a soft, dry brush or compressed air for cleaning.
• Physical Protection: Protect the receiver from physical impact and vibrations. Mount it securely within your model.
• Antenna Care: Ensure the antenna is not cut, kinked, or damaged. Proper antenna placement is crucial for optimal range.

6. Troubleshooting

• Receiver Not Binding / LED Blips:
  • Ensure the bind plug is fully inserted into the "BIND" port.
  • Verify the bind plug's orientation; the negative pin is typically furthest from the board.
  • Check power connections to the receiver. Ensure sufficient voltage (3.6-10V).
  • Confirm your transmitter is in DSM2 mode and its bind function is correctly activated.
• Loss of Binding After Power Cycle:
  • Some units may require re-binding if power is disconnected. Perform the binding procedure again.
  • Ensure the bind plug is removed before disconnecting power after a successful bind.
• No Control Response:
  • Confirm the receiver is successfully bound (solid LED).
  • Check all servo and ESC connections to the correct channels.
  • Verify that servos and ESCs are receiving power.
  • Ensure your transmitter is powered on and functioning correctly.
• Limited Range:
  • Check for damage to the receiver antenna.
  • Ensure the antenna is positioned optimally and not shielded by carbon fiber or metal components.
  • Avoid operating in areas with high 2.4GHz interference.
