Changing the Lighting and Contrast
You can change the level of backlighting and contrast for the screen and
the keys. The key lighting is set the same as the display 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.
2. Press the soft key below the LIGHT control, if it is not already
highlighted.
Alternatively, you can press the trackpad left and right edges to
move sideways between the controls to select the LIGHT soft key.
3. The LIGHT key toggles lighting ON/OFF.
4. Press the trackpad top or bottom edge to increase or decrease the
setting, selecting one of the eight lighting levels. 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 appropriate soft key, or the right arrow on the trackpad, to
select the contrast control. 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.
If the 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 level of
42%. The lighting level is retained until you reset it. 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 on power-up as
follows:
Contrast set < 30% restored to 30%
Contrast set > 70 % restored to 70%
