There are 3 options available when you enter the Shutdown menu on your recorder, Shutdown, Reboot and Lock Screen.
Shutting Down The Recorder
Selecting the Shutdown option will turn the recorder off. The recorder will not capture footage when shutdown so you should only do this when it is absolutely necessary.
Rebooting The Recorder
When you select the Reboot option the recorder will shutdown and restart automatically. You would usually do this to fix any technical errors you may be having just as you would when you restart your computer. You can schedule reboots to ensure every thing is working as it should be as shown in the Auto Reboot section.
Logging Out Of A User Account
Selecting the Lock Screen option will log you out of the recorder so when the next person comes to use it they would have to log in before they can perform any actions. This is handy if the recorder is in an area where other people, besides the operator, could get access.
Confirming Selection
Once you have made your selection click the OK button to confirm. If you want to exit the Shutdown screen click the Cancel button.
