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

trast levels retained, or press

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%
Changing the Brightness & Color Settings (L760)
The
MULTI
key on the L760 color LCD displayprovides 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 fishfinder 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.
