4.3 Receiver Binding

To establish communication between your RC8X transmitter and receiver (R8FG or R4FGM V2.1), follow the binding procedure outlined in the Quick Start Guide. This typically involves powering on the receiver while holding a bind button, then initiating the binding process on the transmitter.

4.4 FPV Setup

The RC8X supports First-Person View (FPV) functionality by connecting an external 5.8G image transmission system. This allows the transmitter's screen to display live video from your RC vehicle.

1. Connect your FPV receiver to the RC8X using the appropriate cables (typically a 3.5mm audio jack for video input and a USB-C cable for power/data).
2. Navigate to the 'System menu' on your RC8X.
3. Select 'External input output'.
4. Set 'Multimedia Mode' to 'Video input'.
5. Ensure 'Pop-up window' is set to 'Open' if you want the FPV feed to appear automatically.
6. Power on your FPV camera on the vehicle.
7. On the FPV receiver, press the CH1 button to search for the camera's signal.
8. Once connected, the FPV feed will appear on your RC8X screen.
