Hello Pam. To factory reset your LS800 Projector, start by going into your Android TV Settings. Select Device Preferences > About > Factory Reset. A confirmation screen will appear, and then you can choose "Erase Everything." Please ensure that you write down the settings you do not want to lose before resetting the projector. All information, including installed apps, Google account login information, and Projector Settings, will be deleted. Regards, Kevin - The Epson Team.
