Getting Started
Watch for this symbol in the margin. It identifies examples
or keystrokes that are shown in ALG mode and must be
performed differently in RPN mode. Appendixes D, E, and F
explain how to use your calculator in RPN mode.
The mode affects only arithmetic calculations ― all other operations,
including the Solver, work the same in RPN and ALG modes.
Power On and Off; Continuous Memory
To turn on the calculator, press
C
(clear) (note ON printed below
the key). To turn it off, press
@
and then
C
. This shifted function is
called
o
(note OFF printed above the key). Since the calculator has
Continuous Memory, turning it off does not affect the information you’ve
stored there.
To conserve energy, the calculator turns itself off after 10 minutes of no
use.
If you see the low battery symbol (
) at the top of the display, you
should replace the batteries as soon as possible. Follow the instructions
on page 224.
Adjusting the Display Contrast
The display’s brightness depends on lighting, your viewing angle, and
the display contrast setting. To change the display contrast, hold down
the
C
key and press
