For Chase mode to operate correctly the GX9000 and the timecode source

This is to ensure that the unit’s timecode generator and the source machine
generator are counting at exactly the same rate.

The GX9000 will “Flywheel” if the input timecode that it is chasing drops out.
This means that playback will continue at the current rate until the timecode
reappears.

The flywheel value represent how many frames must be lost before the
GX9000 will assume that the incoming timecode has stopped and will stop
playback. In Infinite Flywheel mode the GX9000 will forever ignore the
incoming timecode once lock is achieved.
