Rotation Type
The 3 rotation type buttons, ROT POS, ROT SPD, and
ROT MAG
are mutually exclusive and toggle on and off.
Only one of these buttons can be on at a time.
The ROTATE knob, located adjacent to the three rotation type
buttons, controls whichever mode is enabled. The knob setting for
each of the three rotation modes is remembered even when the
modes are de-selected.
ROT POS (rotate position) allows rotation of the wipe pattern to a
fixed angle. With this mode on, turning the ROTATE knob from its
mid-position rotates the entire wipe pattern up to four complete
rotations, either clockwise or counterclockwise.
ROT SPD (rotate speed) allows constant rotation of the wipe
pattern at a rate adjusted by the ROTATE knob. Turning the knob
clockwise or counterclockwise from mid-position causes the wipe
pattern to rotate up to a maximum of four rotations per second.
ROT MAG (rotate magnitude) causes the wipe pattern to rotate as
a function of the transition position (lever arm or auto transition).
The amount and direction of rotation is adjusted by the ROTATE
knob. Turning the knob clockwise or counterclockwise causes the
wipe pattern to rotate up to a maximum of four rotations during
the course of the wipe transition. The starting angle (or position)
of the pattern is determined by the ROT POS value.
