PRECAUTIONS:

1. The distance the remote control will work at reduces as the power gets lower and lower on both the drone and the remote control. Make sure to keep fresh batteries in the remote and use caution when flying too high/far for long periods of time.
2. When the drone's power is low, it becomes more difficult to take off and fly high.
3. If the drone becomes damaged, stop flying it immediately and repair it. This is to prevent further damage or causing injury.
4. If you are not going to use the remote control for a long time, please remove the batteries to avoid battery leaking/corrosion.
5. Do not drop or throw the remote control. Doing so can damage the components and cause it to stop working.
