NOTES
Display examples shown in this Users Guide are intended for illustra-
tive purposes only. The actual text and values that appear on the dis-
play may differ from the examples shown in this Users Guide.
Backlight brightness may appear somewhat unstable immediately after
the keyboard is turned on. This does not indicate malfunction, and bright-
ness will stabilize after a few seconds.
The back lighting of the display is provided by a fluorescent light,
which loses its brightness over very long periods of use. When this
happens, contact your original dealer or a CASIO service provider
about having the backlight replaced. Note that you will be charged for
such replacement.
Adjusting Display Contrast
Display contrast can be adjust to one of 100 levels for easy view-
ing.
Adjusting display contrast helps to make figures easier to read from
any viewing angle.
Within five seconds after pressing the CONTRAST button, press [+]
to increase the contrast value (making the display darker) or [] to
decrease it (making the display lighter).
After you release CONTRAST, the message Contrast remains on
the display for a few moments, during which you can change the
contrast setting further using [+] and [] or by inputting a contrast
value with the number keys.
The contrast can be set to a value from 0 to 99. The initial default
setting is 50.
