Brightness and Color Settings (Color Displays)
The
MULTI
key on a color LCD unit provides controls to set up the display colors
and brightness. You can choose the background color and the color threshold;
color threshold lets you determine which echoes are displayed, by selecting the
minimum color strength the sounder uses.
You can also select the color set, for a bold or soft color palette. The brightness of
the screen can be adjusted over a wide range, suitable for viewing in daylight
(high brightness level) or at night (low brightness level).
The key lighting is automatically adjusted as you alter the screen lighting, so that
you can always find the keys. If you set the backlight to a high level, the key
lighting is dimmed; if you set the backlight to a low level, the key lighting level is
increased.
