Pull down the left thumbstick (or right if you're left handed) on the menu that appears, at the bottom you should see a little icon that looks like a world. Point your laser at it and press the trigger. Point the laser at the mirror plane and trigger to select, then press the green gear button and select the green gear icon for settings.
They've added a whole bunch of menu options since the manual was written so a lot of stuff has changed 😉
