Important Notes

- Performing a master reset will erase all user data, including waypoints, routes, and personal settings. It is advisable to back up any important data before proceeding with this reset.

- If you encounter issues after resetting, ensure that your device has a clear view of the sky for at least 20 minutes to reacquire satellite signals[1][3].
