Binding Procedure

Note: the red receiver LED will turn off when successful connection.

  • Click the bind-button meanwhile powering on the board, either by connecting the battery or USB power. Then the receiver will enter bind mode, indicated by red receiver LED flashes quickly.
  • Now, on the radio, enter the bind status(or what it takes to enter bind status). This receiver only supports AFHDS 2A mode and does not support AFHDS mode, please turn on this mode in your radio transmitter before use. 
  • The red receiver LED should turn off when binding is completed and successful.

You should keep the antenna away from the FC board to get a stronger signal. For example, run the signal upwards.
