Get to know your new VISIO 24 14
There is a round knob in the middle of the control unit. This is the zoom or mag-
nification slider that you use to adjust the magnification. Turning clockwise in-
creases the magnification, turning counterclockwise decreases it. Now turn the
zoom control counterclockwise as far as it will go to minimum magnification.
The minimum enlargement level is less for reading and more for providing an
overview of the original. This makes it easier for you to find the area that you
want to look at enlarged. Visio 24 always starts at the last zoom level set.
Now press the Image button. The
Image button is located directly to the right of
the zoom slider. Pressing the image button switches on the real color display, i.e.
the VISIO 24 image mode. This setting is ideal for viewing photos, but it is also
useful for reading documents that are of poor print quality. You see all colors and
gray values in a natural representation.
Now move the XY-table so that you can see one of the images of the template. If
the image is too small, you can increase the magnification by rotating the zoom
lever clockwise. If you got “lost” on the template because you accidentally moved
the template, turn the zoom control counterclockwise to a smaller magnification,
look for the correct position in this overview and then enlarge the image again.
Now that you have learned a lot about your new VISIO 24, let's read a text.
Move the XY-table to a point on the template where you can find related text.
Now press the text button. The Text button is to the right of the Image button, i.e.
the second button to the right of the zoom controller. The original is now dis-
played with increased contrast and only two false colors. Press the Text button
again to swap the foreground color and background color. Press the Text button
a few times to familiarize yourself with the changes to the display and also toggle
between image display and text display. Do you know the difference? In text
mode, the font appears much clearer and richer in contrast, in picture mode you
can see all the colors and gray values.
Don't like the two colors in text mode? No problem!
You have the choice between 12 different false color combinations. With the in-
version, i.e. reversing the foreground and background color, you have a choice of
24 different representations. Select a different color combination by pressing the
