6.3.3
Auto-fit focus
The Auto-fit focus setting controls approximately how many lines of text are visible at one time. The
fewer the lines, the larger the text is. For example, if you select the 1 text line option, the text is enlarged
to fit the height of the screen. If you select 5 text lines, the text is enlarged to a much smaller degree.
Auto-fit focus is applicable only if you have already set the Zoom factor parameter to Auto-fit focus.
To change the number of lines visible on the screen at one time:
•
Press [TALKS], [7] to view more lines on the screen, or [TALKS], [8] to view fewer lines.
Note: This key sequence changes the number of visible lines only if the Zoom factor parameter
is set to Auto-fit focus.
Or
•
On the Magnification tab, select Auto-fit focus, and then select a number of lines.

Color processing
Using the Color processing setting, you can customize the color display to make the text more readable
for you. You have the following options:
•
None: Retains the original screen colors
•
Black/white: Replaces the colors with a high-contrast black-and-white display
•
Greyscale: Replaces the colors with shades of gray
6.3.5
Invert colors
Use the Invert colors setting to reverse the colors on the screen and create a negative of the image to
improve readability. For example, when you set Invert colors to Yes, black areas become white, and
white areas become black.
To invert the colors or reset them to the original colors:
•
Press [TALKS],[Long *].
6.3.6
Scrolling speed
By default, the magnifier scrolls across the screen automatically. The Scrolling speed setting controls the
speed of this automatic scrolling (see section 6.3.7) as well as the speed at which you can scroll manually
with the navigation keys. You can select a value from 1 (slowest) through 6 (fastest).
6.3.7
Auto-scroll delay
As described in section 6.3.6, the magnifier scrolls across the screen automatically. However ZOOMS
waits for a short period of time after the last change on the screen before the automatic scrolling begins.
Use the Auto-scroll delay setting to control how long ZOOMS should wait before beginning the
automatic scrolling. You can select a value from 0.25 second to 4 seconds. If you don't want the magnifier
to scroll automatically, select No. You can scroll manually with the navigation keys.
The speed at which the magnifier scrolls depends on the Scrolling speed setting (see section 6.3.6).
