Quick-Start Binding Guide (Click to Expand)
  1. Configure Transmitter: In your Radio's Model Setup menu, turn the Internal RF OFF. Set External RF to "Multi" and select the protocol matching your receiver (e.g., DSMX, SFHSS).
  2. Enter Bind Mode: Put your aircraft or receiver into bind mode (holding the bind button or using a bind plug). Once the receiver light is flashing, select the [BND] option on your radio screen.
  3. Confirm Link: The receiver light will typically turn solid once linked. Power-cycle your model and verify control surface movement before flight.

Ethos Tip: Remember to run the LUA script first to enable the Multi-protocol selection menu on FrSky Ethos systems.
