kKey Markings
Many of the calculator’s keys are used to perform more than one function. The functions
marked on the keyboard are color coded to help you find the one you need quickly and
easily.

The following describes the color coding used for key markings.
Color Key Operation
Orange Press !and then the key to perform the marked function.
Red Press aand then the key to perform the marked function.
#Alpha Lock
Normally, once you press aand then a key
to input an alphabetic character, the keyboard
reverts to its primary functions immediately.
If you press !and then a, the keyboard
locks in alpha input until you press aagain.

uTo select an icon
1. Press mto display the Main Menu.
2. Use the cursor keys (d, e, f, c) to move the highlighting to the icon you want.
3. Press wto display the initial screen of the mode whose icon you selected.
Here we will enter the STAT Mode.
•You can also enter a mode without highlighting an icon in the Main Menu by inputting
the number or letter marked in the lower right corner of the icon.
Currently selected icon

The following explains the meaning of each icon.
Icon Mode Name Description
RUN •MATrix Use this mode for arithmetic calculations and function
calculations, and for calculations involving binary, octal,
decimal, and hexadecimal values and matrices.
STAT isticsUse this mode to perform single-variable (standard
deviation) and paired-variable (regression) statistical
calculations, to analyze data and to draw statistical
graphs.
GRaPH-TaBLe Use this mode to store functions, to generate a numeric
table of different solutions as the values assigned to
variables in a function change, and to draw graphs.
DYNAmic graph Use this mode to store graph functions and to draw
multiple versions of a graph by changing the values
assigned to the variables in a function.
RECURsion Use this mode to store recursion formulas, to generate a
numeric table of different solutions as the values assigned
to variables in a function change, and to draw graphs.
CONICS Use this mode to draw graphs of implicit functions.
EQUAtion Use this mode to solve linear equations with 2 to 30
unknowns, and high degree (2 to 30) equations.
PRoGraM Use this mode to store programs in th program area and
to run programs.
Computer Algebra Use this mode to perform algebraic calculations.
System to make other system settings.
ALGEBRA Use this mode for step-by-step solution of expressions.
to make other system settings.
TUTORial Use this mode to determine the expression type and
solve mode, and for interactive equation solutions.
LINK Use this mode to transfer memory contents or back-up
data to another unit.
MEMORY Use this mode to manage data stored in memory.
SYSTEM Use this mode to initialize memory, adjust contrast, and
to make other system settings.

kAbout the Function Menu
Use the function keys (1to 6) to access the menus and commands in the menu bar
along the bottom of the display screen. You can tell whether a menu bar item is a menu or a
command by its appearance.
• Command (Example: )
Pressing a function key that corresponds to a menu bar command executes the command.
• Pull-up Menu (Example: )
Pressing a function key that corresponds to a pull-up menu opens the menu.
You can use either of the following two methods to select a command from a pull-up menu.
•Input the key to the left of the command on the pull-up menu.
•Use the fand ccursor keys to move the highlighting to the command you want, and
then press w.
The symbol 'to the right of a command indicates that executing the command displays a
submenu.
To cancel the pull-up menu without inputting the command, press i.

kAbout Display Screens
This calculator uses two types of display screens: a text screen and a graphic screen. The
text screen can show 21 columns and 8 lines of characters, with the bottom line used for the
function key menu. The graph screen uses an area that measures 127 (W) ×63 (H) dots.
Te xt Screen Graph Screen
The contents of each type of screen are stored in independent memory areas.
Press u5(G↔T) to switch between the graphic screen and text screen.

#The symbol ↑in the upper left corner of a pull-
up menu indicates that there are more
commands running off the top of the menu.
Use the cursor keys to scroll the menu contents to
view the commands running off the top.

kNormal Display
The calculator normally displays values up to 10 digits long. Values that exceed this limit are
automatically converted to and displayed in exponential format.
uHow to interpret exponential format
1.2E+12 indicates that the result is equivalent to 1.2 ×1012. This means that you should move
the decimal point in 1.2 twelve places to the right, because the exponent is positive. This
results in the value 1,200,000,000,000.
1.2E–03 indicates that the result is equivalent to 1.2 ×10–3. This means that you should move
the decimal point in 1.2 three places to the left, because the exponent is negative. This
results in the value 0.0012.
You can specify one of two different ranges for automatic changeover to normal display.
Norm 1 .................. 10–2 (0.01) > |x|, |x| >1010
Norm 2 .................. 10–9 (0.000000001) > |x|, |x| >1010
All of the examples in this manual show calculation results using Norm 1.
See page 2-3-2 for details on switching between Norm 1 and Norm 2.

kCalculation Execution Indicator
Whenever the calculator is busy drawing a graph or executing a long, complex calculation or
program, a black box “k” flashes in the upper right corner of the display. This black box tells
you that the calculator is performing an internal operation.

kInputting Calculations
When you are ready to input a calculation, first press Ato clear the display. Next, input your
calculation formulas exactly as they are written, from left to right, and press wto obtain the
result.
○○○○○
Example 1 2 + 3 – 4 + 10 =
Ac+d-e+baw
○○○○○
Example 2 2(5 + 4) ÷(23 ×5) =
Ac(f+e)/
(cd*f)w
kEditing Calculations
Use the dand ekeys to move the cursor to the position you want to change, and then
perform one of the operations described below. After you edit the calculation, you can
execute it by pressing w. Or you can use eto move to the end of the calculation and input
more.
