About VISIO 24 5
2 About VISIO 24
Attractive design, simple operation, excellent image quality - that's what VISIO 24
stands for.
Visio 24 has a high-resolution camera and a 24 “widescreen monitor in 16:9 for-
mat with energy-saving and high-contrast LED lighting. The high resolution of the
camera ensures a razor-sharp image even at the smallest magnification.
The VISIO 24 has a XY-table and a color camera, also has 6 control buttons and
offers an extremely wide range of functions such as an adjustable reading line.
VISIO 24 is one of the one of the smallest, lightweight and best designed devic-
es. It is characterized by its extraordinary design. VISIO 24 has all the properties
you would expect from an excellent screen-reading device.
In addition to full color display and autofocus, VISIO 24 has numerous false color
display options. Reversal of foreground and background color is of course also
available. There is also the option to switch off the auto focus, e.g. to fill out forms
or to make handwritten notes. Thanks to the image optimization function, VISIO
24 always offers optimal image quality.
VISIO 24 is able to display even documents of very poor quality, such as pale
print or crumpled, dirty paper, in a legible manner on the screen. Despite the high
technical effort, it can happen that in rare cases an original cannot be displayed
more legibly, e.g. with highly reflective reading material.

Setting up the VISIO 24 on the table 7
4 Setting up the VISIO 24 on the table
Place your VISIO 24 on your table in such a way that the front edge of the XY-
table, which has been fully extended to the front, is just flush with the edge of the
table. Even with maximum movement of the XY-table to the left or right, it must
not protrude over one of the table edges. This ensures that the device is in a safe
position.

You can skip this chapter, as the following steps were usually carried out when
the device was delivered and are only mentioned here for the sake of complete-
ness.
Connect the power pack of your VISIO 24 to a live power socket and the plug on
the other side of the power pack into the camera unit. The power supply input
(see Figure 2) is on the right-hand side of the camera unit. The ready LED lights
up immediately after plugging in and lights up continuously.

Switching on for the very first time after assembly 9
Press the power switch on the far left of the control unit below the monitor for
about a second. As soon as the lighting switches on, you can release the switch.
The monitor also switches on immediately. (Note: The white control lamp on the
right at the lower edge of the monitor lights up continuously.)
If necessary, the power-on-switch of the monitor is directly under the control
lamp. You can place your finger on the lower right edge of the screen and move it
to the left until you feel the slight bump of the power button. After pressing this
button, the power-on control lamp lights up white. VISIO 24 from now automati-
cally switches on the monitor.

These steps only need to be done when switching on for the first time after deliv-
ery. Then it is sufficient to switch VISIO 24 on and off on its control unit.

You have already learned how to set up VISIO 24 optimally on your table and
how to supply VISIO 24 with power.
You can tilt the screen slightly for more comfortable reading. Do not try to tilt the
screen too far by going past the stop.
VISIO 24 has a height adjustment of the screen!
Move the monitor up and down together with the control panel. You do not need
any tools for this.
Picture 5
Proceed as follows:
[Important: always keep one hand at the bottom of the monitor]
Tilt the monitor back slightly.
Turn the two fixing screws (see arrows in Figure 5) on the back of the monitor
half a turn to the left.
Grasp the top and bottom of the monitor and slide it to the desired height.
Tighten the two fixing screws again to the right.

Get to know your new VISIO 24 13
Now switch on VISIO 24 to use it.
The control unit is located directly in the middle under the screen. The on-
switch is on the far left. Press the power button for about a second to turn on the
device. As soon as the lights come on, you can let go of the switch. The monitor
may display the message like "out of range ..." until you see the enlarged original
on the screen after a few seconds.
To switch off VISIO 24, you have to press the on switch for longer than a second.
This prevents you from switching off the VISIO 24 by accidentally briefly touching
the switch. Practice turning it on and off a few times, then leave it on for the next
few steps.
Place a template on the XY-table. Take something colored, maybe a brochure or
magazine with text and colored pictures.
To align the template exactly horizontally, push it back against the silver rear
edge of the XY-table. If you now slide the XY-table from left to right, you will not
slip in the line, as the template aligns itself on the edge parallel to the guide direc-
tion. This little trick will make your reading a lot easier.
The XY-table has a brake for locking. You will find the brake lever on the front
edge of the XY-table. Move the lever all the way to the left to be able to move the
XY-table freely in all directions. With the lever in the middle position, you can
move the XY-table slightly to the right and left; the movement to the front and
back is blocked. In the rightmost position, the table is firmly locked in all direc-
tions.
Now align your template with the rear edge of the XY-table and move the brake
lever all the way to the left.
Attention: Avoid getting your fingers or clothing into the mechanics of the
XY-table below the reading plate to prevent them from being trapped. Keep your
hands above the plate or on the front edge. Do not reach under the side or rear
edges of the reading plate.
Now let's try the buttons on the control unit. You already know the on-switch on
the far left of the control unit.

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

Get to know your new VISIO 24 15
false color key. This is the rightmost button on the control unit. Each time you
press this button, the color combination changes. When you have done all 12
combinations, it starts again with the first one. To swap the foreground and back-
ground color, press the text key.
The following color combinations are available:
Black-White, Black-Yellow, Black-Green, Black-Magenta, Black-Cyan, Blue-
Yellow, Blue-White, Black-Ivory, Black-Soft_Yellow, Black-Soft_Peach, Black-
Soft_Pink, Blue-Ivory
Select your preferred color combination with the false color key and, if necessary,
press the text key to swap the foreground and background color. Take the time to
find the setting that works best for you.
In picture mode, the false color key has a different function. Here you can change
the white balance. Press this button to toggle between a neutral white (default
setting), a warm shade of red, which is good for viewing photos with skin tones,
or a cool blue and white, which is especially suitable for reading colored text.
Note: VISIO 24 remembers the setting of the false colors. So if you switch from
text mode to picture mode and then return to text mode, you will find the previ-
ously set color combination and inversion there.
Now that you have found your preferred color setting for reading in text mode, we
now want to turn to the more problematic templates. In most cases, VISIO 24 will
display your enlarged original with good contrast, thanks to its automatic expo-
sure. This is also easy with clean, black printing on pure white paper.
Sometimes it happens, however, that the template is not ideal and the automatic
system does not find the best setting. This can happen, for example, with colored
writing or a colored background, or with poor photocopies with pale letters on
gray paper. In these cases we use the image optimization button. It's the third
button from the left, just to the left of the zoom controller. With this button you can
regulate the automatic capture range in five stages.
So if you ever get a poorly legible picture from VISIO 24, simply press this button
until the picture is best represented.
This button is effective in picture mode and text mode.

Get to know your new VISIO 24 16
Note: Often you just know that the last setting was the best when you are already
one too far and the picture gets worse again. Since there are five different set-
tings that run up and down, you only need to press the button seven times in
succession to return to the previous setting.
Another help to find your way around a text is the reading line.
To activate the reading line, first set the desired magnification on the magnifica-
tion control.
Now press the center of the magnification control and release it shortly after-
wards. You will notice that a black horizontal line is now displayed over the pic-
ture on the screen.
You can now adjust this reading line with the magnification control clockwise up-
wards and counterclockwise downwards, the magnification does not change.
You can hide the reading line again by briefly pressing the magnification control
repeatedly.
Reading gap feature is used to hide the image area above and below a line to
be read and is activated by pressing and holding the zoom control. When you are
in picture mode and have set the desired magnification, press the magnification
control for about a second and release it than.
A reading gap is now shown in the middle of the screen. You can adjust the width
of this reading gap to your needs using the magnification control. To widen the
reading line, turn the magnification control to the right; to display it more narrowly,
turn the magnification control to the left.
The rest of the picture is black. You can hide the reading gap by pressing the
zoom control again for about a second.
Note: The reading line and reading gap can also be displayed in all false color
modes In addition, the reading line adapts to the false colors. For example, if
you set yellow font and black background, the reading line is automatically yel-
low. You can also display the colored reading line in real color mode by pressing
the image button. After restarting the Visio 24, the reading line color is always
black.
Now we will explain the function of the autofocus button. It may sound compli-
cated, but it is very easy!
After switching on, the autofocus, i.e. automatic focusing, is always switched on.
This means, no matter how thick the book you want to read, or how curved its
surface, VISIO 24 always shows the enlarged section in focus. This is why you
will usually work with this setting.

Get to know your new VISIO 24 17
Sometimes, however, you want to fill out a form or a crossword puzzle, you may
also want to paint your fingernails or take a closer look at a 3-dimensional object.
This is where the fixed focus comes into play.
The autofocus button is the second from the left on the control unit. If you press
this, you switch the autofocus between on and off.
Now let's try how it works. If you've messed around with this button, press the au-
tofocus button once and turn the zoom control a little to the right.
VISIO 24 enlarges the original and focuses it automatically.
If this is not the case, press the autofocus button repeatedly and the VISIO 24 will
focus the original.
Now place your hand on the template. VISIO 24 now enlarges your hand and you
can see that your skin is now in focus and the letters at the edge are blurred. The
same thing can happen when you want to fill out a form. Instead of making the
letters sharp, it is possible that your hand, which is holding the pen, is sharp and
the letters are blurred. If you take your hand away, the letters become sharp
again.
Now let's try the same thing with the autofocus off. To do this, place a form on the
XY-table. You can see that the letters are sharp, press the autofocus button
again to switch it off. If you now fill in the form with a pen, VISIO 24 will still keep
the letters in focus and will no longer focus your hand. When you're done, don't
forget to turn the autofocus back on with the autofocus button.
An additional feature of your Visio 24 is to switch itself off after 4 hours without
use. Should you accidentally not switch off your Visio 24, it will switch off itself af-
ter this time.
You did it! You are now familiar with all the setting options and functions of VISIO
24.
We hope you enjoy your new VISIO 24 CCTV device.
