The jog/shuttle knob, shown in the figure below:
It is a combination of a shuttle ring with an embedded jog disk, which is used to provide
wide latitude in playback control. Note that the jog/shuttle knob is active only when the
DVR unit is in Playback mode.
While playing back video, you can use the shuttle ring to select different speeds of
forward and backward playing. Rotating the shuttle ring counterclockwise causes the
unit to playback in fast forward/ backward playing speed. According to the angle you
rotate the shuttle ring, you can choose the playing speed from 1x, 2x, 4x, 8x, 16x, and
32x, in both forward and reverse directions, shown in the figure below:
Inside the shuttle ring is the jog disk, shown in the illustration below, it can turn
completely in either direction. Once you freeze the video, you can use the jog disk to
go to single-step play back. Clockwise rotation causes forward one-step playback; and
counterclockwise rotation causes backward one-step playback.
