Could someone please tell me what the switch does on the main bottom right under get help? Thanks!

Hey， sorry for the inconvenience this Chinese option has caused you.  It is used to active the  drone. To achieve it, you can connect to the internet, switch this option on to enable the system to sync your activate info.  For further assistance, you may contact support at this link :https://www.ryzerobotics.com/support

Thank You!!!

It's My pleasure. If we can be of service to you again, please do feel free to let us know. Happy droning !
