American Dynamics SpeedDome Ultra 8 Operator's Manual page 68

A random scan pans randomly between the left and right scan limits. For example, the scan
may start at point in the scan, then pan right 40° and pause, pan right 10° and pause, pan left
20° and pause, and pan right until it reaches the right scan limit. Figure 57 illustrates a random
scan. In this figure, the dashed line represents the scan area, and the solid line represents the
scan pattern. The circle on the scan represents the start point. Each arrowhead represents a
pause. "X" represents a change in direction.
