natural colors in all shades.
If a PC is connected and you see the PC image on the screen, the
picture button will switch back to the camera image.
Now, move the reading table until you see one of the images of your
document appear on the screen. If the image is too small, increase the
magnification by turning the zoom control clockwise. If you get lost and
do not know where you are on the document, decrease magnification,
find your place on the page, and then increase magnification again.
NOTE: if you are using high levels of magnification, you may find it
easier to increase magnification in increments, make adjustments to the
placement of your document, and then repeat. If you move quickly from
the smallest to the largest magnification, what was once in the middle of
the screen will have disappeared.

are much clearer and brighter with higher contrast, whereas in true
colors you see all colors and shades of grey.
You see the difference? Black on white and white on black or any other
false colors in Text mode will show crisper characters in higher contrast,
whereas the true color mode shows you real colors and all shades of
grey.
