Activating the
backlighted
screen and
keyboard
To use the unit in a low-light environment, every CE8000 Series unit is
equipped with a backlighted screen. Optionally, CE8000 Series unit can also
be equipped with a backlighted keyboard.
NOTE: Backlighting can drain batteries rapidly if used constantly.
Only use it when necessary in a low-light environment.
To activate the backlighting of the screen and keyboard, press the blue key
and then the backspace key. The same sequence will deactivate this
feature.
Backlighting normally turns off by itself after 45 seconds if there is no key
pressed or new information on the screen.
The backlighted keyboard has two distinct zones: (Figure 1)
•
The numerical section
•
The alpha section
Normally, both zones of the keyboard will be backlighted but under software
control only one zone at a time can be backlighted.

the Display
