READJUSTING THE CONTRAST, USING THE
BACKLIGHT
Turn the contrast control knob (23,8) slowly clockwise so
that the information appearing on the screen can be read
clearly. In the maximum and mlnlmum positions
(maximum/minimum contrast) nothing can be distinguished on
the screen.
At this point we recommend you switch ON the backlight and
readjust the contrast. Depending on the lighting conditions
at your work location you will find a significant
improvement in readability/clarity when text/graphic is
displayed on your system.
Switch the backlight OFF and ON and observe the difference.
Since you will be using your system in many different
environments adjust the display angle, the contrast knob
and
the backlight for optimum readability on your display.

The first time you turned your system on, because of
the adjustments you have been making to the contrast
and to the backlight, it is possible that you could not
see some of the information displayed; we therefore
recommend, at this point, that you switch the system
off, wait for several moments, and then switch on again
(HARDWARE RESET). (Obviously, this operation of
switching the system off and then on again is not
necessary when the contrast control knob is left in the
normal working position.)
