### Low-voltage Alert

The setting of Second Level Protection is the same as First Level Protection. When it is triggered, the LED warning will be on and the multi-rotor will descend. Meanwhile the center point of throttle stick cannot hold the aircraft hovering, so that the aircraft will descend slowly.

Tips

- When the second level protection is triggered, the center point of throttle stick will move up slowly to 90% of endpoint, in order to keep the aircraft hovering.
- When the center point is at 90% of endpoint, aircraft will still start to ascend slowly if you continue to pull the throttle stick, and the control of Pitch, Roll and Yaw are the same as before. Please land ASAP to prevent your aircraft from crashing or other harmful consequences!
