Brightness and Color Settings (Color Displays)

To change the lighting and contrast:
1. Press the MULTI key (or the MULTI knob on CRT radar units) to
display the soft key controls:
The last-used soft key is highlighted in inverse video (white text
on a black background).
POWER
AUTO LO HI
2. Press the LIGHT soft key if it is not already highlighted.
3. The LIGHT soft key toggles lighting ON/OFF.
4. Use the trackpad (up or down) to increase or decrease the setting.
You can press and hold the trackpad to change the setting more
rapidly. The lighting level is adjusted as you change the setting.
5. Press the CONTRAST soft key. Adjust the setting in the same way as
for the lighting. There are 64 different contrast levels.
6. Press ENTER to return to the default screen, with the new lighting
and contrast levels retained, or press CLEAR to discard the
changes and return to the default screen.
If lights are left ON when you switch off the display, the next time
the display is switched on, the lights will be ON, but at the default
setting of 42%. The new contrast level is retained until you reset
it, unless you set the control very low or very high; in this case,
the contrast will be restored as follows:
Contrast set < 30%restored to 30%
Contrast set > 70%restored to 70%
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.
