The Transition LEDs next to the T-Bar reflect the state of the transition, not the position of
the physical T-Bar . Often they will be the same — but sometimes, the physical T-Bar
position and the "virtual" T-Bar position may not match.
To learn about physical and virtual T-Bar positions, please practice the following examples.

Use the following steps to demonstrate physical vs. virtual T-Bar position, in normal

Press AUTO TRAN again (during the interval) to pause the transition at 50%.
Physical and virtual T-Bar positions do not match. In this situation, the T-Bar has
no effect on the video unless you move it up to 50%, and match the physical
position with the virtual position.
