When you want to open the screen, slide the latch release buttons
on both sides (shown below) away from the center. Then lift the
screen back. You can position the screen at a variety of viewing
angles.
Note
To prevent damage to the system, you cannot open the Equity
LT-286 while it is standing uptight on its back panel. Set the
computer in a horizontal position before opening it.
If you close the screen while the computer is running, the screen's
backlighting is automatically turned off to conserve battery charge.
When you reopen the screen, the backlighting comes back on
automatically, unless the backlight period has elapsed. If the screen
is dark when you reopen it, press any key.
You may close and reopen the screen while a program is running
without affecting the program in any way.
