When you switch on VISIO, it is always in auto focus mode. That means, no
matter how thick a book or how curved a page, VISIO will always focus on the
part displayed and thus always present a sharp image on the display. So this is
the setting you usually will prefer.
However, sometimes you want to fill in forms or crosswords or you want to
paint your nails or view three-dimensional objects. This is where fix focus
comes into play.
First, let us find that button. The auto focus button is the second button from
the left. Press it to toggle auto focus on and off. On the screen “AF ON“ or “AF
OFF” will be displayed for a few seconds respectively.
Let us test how this works. If you have already played with this button, press
the Auto Focus button once or twice and check for “AF ON” being displayed
to make sure, automatic focus is on. VISIO will magnify the document lying on
the XY-table and display a sharp image. Put your hand on the document now.
VISIO will magnify your hand and you see the skin of your hand is focussed
now while the characters on your document are blurred. The same may
happen when you want to fill in a form. Instead of showing sharp letters,
VISIO may focus on the back of your hand holding a pencil. If you remove
your hand, the characters are sharp again.
So let us try the same with fixed focus now. Place a form on the XY-table. If
VISIO does not show sharp characters, press the auto focus button. “AF ON“
will be displayed. Now that characters are sharp, press the Auto focus button
again to switch it off. “AF OFF“ will be displayed. If you fill in the form with a
pencil now, VISIO will always stay in focus on the characters and not on your
hand. Once finished, do not forget to turn auto focus on again by pressing the
Auto Focus button.
Now you have already learnt about all options on VISIO 22+. We hope you will
enjoy your new CCTV.
