To select the cursor mode and adjust the cursors in either mode, do the following
steps:
1. Press CURSOR ➞ Mode (main) ➞ Independent or Track (side):
Independent makes each cursor positionable without regard to the position of
the other cursor.
Track makes both cursors positionable in tandem; that is, both cursors move in
unison and maintain a fixed horizontal or vertical distance between each other.
2. Adjust the cursors according to the mode you have selected:
To adjust either cursor in independent mode, use the general purpose knob to
move the selected (active) cursor. A solid line indicates the adjustable cursor
and a dashed line the fixed cursor. Press Select to toggle selection between
the two cursors.
To adjust both cursors in tracking mode, use the general purpose knob to
move both cursors.
To adjust the distance between cursors in tracking mode, press SELECT to
temporarily suspend cursor tracking. Then use the general purpose knob to
Set Mode and Adjust the Cursors
