Changing the Lighting & Contrast (Monochrome LCD)
On the L755RC, you can change the level of backlighting and contrast for the
screen and keys. The key lighting is set the same as the screen lighting, except
that it remains switched on at its lowest level even when the screen lighting is
turned off, so that you can always find the keys.
To change the lighting and contrast:
1. Press the MULTI key to display the soft key controls:
The last-used soft key is highlighted in inverse video (white text on a black
background).
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 con-
trast 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:

Changing the Brightness & Color Settings (Color LCD)
The MULTI key on the color LCD Fishfinder 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 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).
