Changing the Lighting and Contrast

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).
Note: If you press MULTI during the magnetron warm-up sequence
countdown, only the LIGHT and CONTRAST sliders are displayed, and the
lighting is automatically switched on at its last-used level.
2. Press the LIGHT soft key 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 soft key toggles lighting ON/OFF.

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 remove the soft key sliders and 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%
Contrast set > 70 %
