If you are in real color mode and press the false colour button, you can
adjust the color temperature. You can choose between the three modes
warm, normal and cold color temperature.
Alternative set of false colors
Visio 500 comes with two sets of 7 false colors each. The standard set
has very bright intense colors, with high contrast. This is appropriate for
most users. The standard colors are: black-white, black-yellow, black-
cyan, black-green, black-magenta, blue-white and blue-yellow.
For special needs, there is a second set of softer colors with less
contrast. This is especially helpful if you are sensitive to blinding effects
from high intensity light.
The alternative colors are: black-white, black-ivory, black-soft yellow,
black-soft peach, black-soft pink, blue-ivory, blue-white.
To switch between the two sets, press picture button and Text button
simultaneously while pressing the power button on power on.
Visio 500 will remember this setting, so you only have to do this once.
Now that you have found your preferred settings, let us try to read some
more complex examples with poor quality print. In most cases, the
automatic contrast feature in Visio 500 will magnify your document and
present it in high contrast with crisp characters. Sometimes however, the
automatic contrast will not find the best setting. That may likely happen
with documents where the print quality is poor, or with colored characters
that are printed on a colored background. In these cases you may want
to experiment with the Image Optimiser button to find the best
settings. This is the third button from the left, directly left to the zoom
knob. The image optimiser button selects one of four levels of
optimisation. So if you do not get a good quality representation on Visio
500 display, simply press this button several times until you get the best
result.
