Pattern Adjustments
Available pattern adjustment controls are described below.
Positioner (Joystick)
The positioner controls operate as follows:
■ Turning on the [POS] button enables the positioner and
returns the pattern to the position it was last moved to. You
can then use the positioner to move the pattern to any screen
position. Turning off the [POS] button disables the positioner.
■ When you press the [CENTER] button, the pattern returns to its
default center position.
Wipe Direction
The three wipe direction buttons are [NORMAL], [REVERSE], and
[FLIP FLOP]
. Normal and Reverse modes cannot both be selected at
the same time. However, Flip Flop mode works in combination
with either Normal or Reverse.
■ When [NORMAL] is on, the white areas on the pattern buttons
indicate new video that will be revealed as the pattern moves.
■ When [REVERSE] is on, the black areas on the pattern buttons
indicate new video.
■ When [FLIP FLOP] is on together with one of the other buttons
(Normal or Reverse), the first wipe transition moves in the
direction indicated by the other lighted button. Then the next
transition moves in the opposite direction (flip flop). This
feature allows you to “wipe on” and “wipe off” using
whichever starting direction you choose.
Mask Preset Pattern/Wipe
The [MASK/PRESET PATTERN] and [WIPE] buttons delegate the
(WIDTH)
, (SOFTNESS), (SYMMETRY), and [MASK/PRESET INVERT]
controls to a mask or preset pattern key or to a wipe pattern. Only
one of the two buttons may be on at a time.
