Changing the Brightness
The MULTI key on the color LCD display is used to adjust brightness. 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.
