Changing Backlight
After power-up, the screen has a high bright display .
To save battery power, the screen has an economic
brightness display when operated on the battery pack (no
power adapter connected).
To change the brightness of the display , do the following:

Dim the backlight.
ô
Brighten the backlight again.
The high brightness increases when you connect the
power adapter.
Note
Using dimmed display lengthens maximum
battery power operation time by about one hour.
