If you reselect the MAIN input
while the Insert function is still
in use, the insert is
automatically cleared, and the
video image switches via the
transition effect from the
current MAIN image to the
newly selected image. If you
want to use the Insert function
again, first bring the fader all
the way to the MAIN side,
then move it to INSERT again.
