Binding Procedure

The binding procedure is reversed as usual. No need to hold the bind button when powering on.

  • Power on the board, either by connecting the battery or USB power. Then the green receiver LED will start to flash.
  • Hold the bind button for 3 seconds until the green receiver LED turns solid. This means that the receiver is in bind mode and you can put your radio transmitter into bind mode to pair up.

For detail procedure of binding, please check the SPI Frsky Receiver Binding Manual.
