Samsung VISIO 22+ User Manual page 11

Let us try the buttons on the control panel now. We have already learned, the
power on button is the leftmost button.
In the middle of the control panel, there is a round knob. This is the zoom
knob which controls magnification. Turning this knob clockwise will increase
magnification while turning it counter clockwise will decrease magnification.
Turn the zoom knob counter clockwise to the end position to obtain
minimum magnification.
The minimum zoom level is not intended for reading; however it gives you a
better overview on the document structure. Thus you can easily find the
position you want to view at higher magnifications.
Now, press the picture button. The picture button is located to the right of
the zoom knob. Pressing this button will set VISIO to real colour or picture
mode. This mode is ideal for viewing images and it also serves for reading bad
print and for writing or filling in forms. It provides all natural colours in all
shades.
So move the XY-table until you see one of the images of your document. If
the image is too small, increase magnification by turning the zoom knob
clockwise. If you got lost and do not know where you are on the document,
decrease magnification, move the XY-Table and increase again.
VISIO will remember the last setting even after power off.
You already know a lot about VISIO now, however let us read some text.
Move the XY-table to a position where you see some text on the display. Now
press the text button. The text button is located to the right of the picture
button it is the second button to the right of the zoom knob. The image will
be displayed in high contrast now and in two false colours only. If you press
the text button again, foreground colour and background colour will be
reversed. Press this button a few times to see the difference, also switch
between text mode and picture mode to see the difference. In text mode,
letters are much clearer and brighter with higher contrast whereas in picture
mode you see all colours and shades of grey.
You do not like the colours shown in text mode? No problem! Let us change
them. You have a selection of seven false colour combinations and with
reversing foreground and background you will have 14 different colour
