Caution on specification of the graphic color
Graphics are classified into multi-color type and black-and-white type. Specification of the
background color and the display color is valid for black-and-white graphics exclusively. (This color
specification is enabled exclusively in the DU type in which color display is available.)
[Graphic type]
• Multi-color type
Color specification is invalid because the color of the
graphic itself has the priority.
• Black-and-white type
The color specification is valid as shown in the figure
(exclusively in the DU type in which color display is
available.)
In the F940GOT, "Indicator" objects can be overlaid on
the screen.
