right, or it doesn't fit properly on the screen, press the
button on the remote control or the
projector. This automatically resets the projector's tracking,
sync, resolution, and position settings. (You must be projecting
an image for this button to have any effect.) The screen turns
black for a few seconds, and then the image appears again. After
the image reappears, it takes about three seconds for the
correction to take effect. Don't press any other buttons while
this is happening.
