This is like a .400 Pro Tree. Click "Stage" button, and the yellow stage light (background)
will come on, then wait for the amber light and .400 seconds later, the green.
Click "Launch" to start once the tree comes down! Go ahead and stage, the amber will
come on within 10 seconds! Remember, the screen will turn yellow,
then amber and then you have .400 seconds to the green!

A .400 is perfect, keep trying until you get it.
