Check the top right of your computer screen—if you see the Airtame control panel bar, click the red Stop icon to stop. If you don’t see the control panel bar, look on the desktop or in the Taskbar area for the Airtame icon (bright blue square with 2 white wavy lines on it), double-click icon to open Airtame control panel, then click red Stop icon to stop Airtame. You’ll know you’ve successfully stopped Airtame when your computer screen is not being displayed on the projection screen.
