What should you do if the TX800 VTX resets to 25mW every time it's powered on?

1. Set the power table groups as follows, with the 5th group assigned to an invalid value like 888: The 5 groups should correspond to 25 mW, 200 mW, 400 mW, 800 mW, and an invalid power level (e.g., 888).

Then click"save"

2.Then set the power level to 400, click Save, and you'll see that the orange LED on the VTX is flashing rapidly, indicating that it is now outputting 400 mW.

3.Now set the power level to an invalid value, like 888, and click Save. You'll notice that the orange LED still flashes rapidly, which means the VTX is still at 400 mW. This setup helps prevent the flight controller from automatically resetting the VTX to 25 mW upon reboot.

Now, whenever you power on the drone, the VTX will stay at 400 mW.

The same method applies if you want to keep it at 800 mW.
