Power LED – Lights when power is applied to the unit.
Freeze – Provides a still image capture of a scan-converted computer
screen. Press to freeze; press again to unfreeze. The LED lights
when Freeze is active. Computer video (local monitor) output is
not affected.
Centering/Pan (Vertical) – This knob has 2 functions, depending on
the position of the Under/Over/Zoom switch. In Under/Over, it is
the vertical position (V. shift) adjustment – shifting the image up/
down on the screen. With the Under/Over/Zoom switch in Zoom, it
becomes the up/down pan control.
Centering/Pan (Horizontal) – This knob has 2 functions,
depending on the position of the Under/Over/Zoom switch. When
not in the Zoom position, it is the horizontal centering (H. shift)
adjustment – shifting the image left/right on the screen. When in
the Zoom position, it becomes the left/right pan control.
Min. Max. LEDs – One of these LEDs lights to indicate the Centering/
Pan range has reached its maximum or minimum limit.
Zoom/Over/Under – This switch provides three ways to view the
displayed image: Underscan, Overscan or Zoom.
• Zoom – The image becomes 200% of standard size. Use the
Under/Over/Zoom switch together with the Centering/Pan control
knobs to zoom and pan the image.
• Overscan – This gives a 10% larger image than standard size.
• Underscan – This is for normal viewing.
__ Nonvolatile memory saves centering adjustments for all views.
Filtering switch (Horz) – Selects from two levels of horizontal
filtering for different types of images. Select the position that gives
the best picture detail.
Filtering switch (Vert) – Selects from three levels of vertical filtering
to eliminate flicker when displaying different types of images, such
as text, graphics, etc. Select the position that gives the best picture.
__ It may be appropriate to change the vertical filtering setting after
switching between the Zoom/Over/Under modes.
