5. Once the progress bar completes, it will display "Download succeed".
6. Recalibrate after the firmware update
Steps for calibration:
Step 1:
- Remove both antennas from the receiver module and make sure there are no video transmitters (VTX) powered on nearby.
- Select a frequency band (e.g., A1 (5865MHz)), then enter the calibration menu. Press the 5-way button to start calibration.
3.After calibration, the screen will show the calibration status and indicate whether it was successful.
Step 2:
- Power on the VTX and set its output power to 25mW, and the frequency to A1 (5865MHz).
- Keep a distance of approximately 1 meter between the VTX and the receiver. In the calibration menu, press the 5-way button to begin calibration.
- After calibration, the screen will show the status and confirm if it was successful.
If calibration fails, it could be due to the following reasons:
- In Step 1, the VTX was not turned off or there were other VTXs using the same channel nearby. ➤ Make sure all VTXs are off or move to an area with less interference during calibration.
- In Step 2, the VTX was not powered on, or the VTX and receiver were not set to the same frequency. ➤ Ensure the VTX is powered and set to the same channel as the receiver.
