Determination of the angular unit
The following three angular units (degrees, radians, and grads) can be specifi ed.
DEG (°): @J00(default)
RAD (rad): @J01
GRAD (g): @J02
Selecting the display notation and decimal places | 1 |
Five display notation systems are used to display calculation results: Two settings of Floating point (NORM1 and NORM2), Fixed decimal point (FIX), Scientific notation (SCI), and Engineering notation (ENG).
•When @J10(FIX) or @J12 (ENG) is pressed,
•When @J11(SCI) is pressed,

•NORM1 (@J13): 0.000000001≤x≤9,999,999,999
•NORM2 (@J14): 0.01≤x≤9,999,999,999
Selecting the editor
Two editors are available in NORMAL mode:
•The WriteView editor
•The Line editor (LINE): @J21
Note: Any entries will be cleared when you change the editor.
Adjusting the display contrast
Press @J3, then +or &to adjust the contrast. Press jto exit.
Insert and overwrite entry methods
When using the Line editor, you can change the entry method from “INSERT” (the default) to “OVERWRITE”.
After you switch to the overwrite method (by pressing @J 41), the triangular cursor will change to a rectangular one, and the number or function underneath it will be overwritten as you make entries.
Name display function
You can save a username in this calculator. When you turn the power off, the saved username is displayed momentarily.
Up to 32 characters may be saved, split over two lines.
Entering and editing the username:
1.Press @J5. The editing screen appears with a fl ashing cursor.
2.Use uand dto scroll
through the available characters. The following characters can be entered (listed in the order that they appear): Letters (A to Z, uppercase only), numbers (0 to 9), slash (/), hyphen
Press @uto jump to “A”, and press @dor jto jump to the space.
3.Pressing lor rmoves the cursor to the left or right. To modify a character, use lor rto move the cursor to the character, then select another character using uor d.
Press @lor @rto jump to the beginning of the fi rst line or the end of the second.
4.Repeat steps 2 and 3 above to continue entering characters.
5.Press =to save.
Note: Press @Z in the editing screen to clear all the characters.
ENTERING, DISPLAYING, AND EDITINGTHE EQUATION 2 
The WriteView Editor
Entry and display
In the WriteView editor, you can enter and display fractions or certain functions as you would write them.
Notes:
•The WriteView editor can only be used in NORMAL mode.
•If the equation grows too large, it may extend off the edge of the display after you obtain the result. If you want to see the entire equation, press lor rto return to the editing screen.
Displaying calculation results
When possible, calculation results will be displayed using fractions, r, and π. When you press U, the display will cycle through the following display styles:
•Mixed fractions (with or without π) → improper fractions (with or without π) → decimal numbers
•Proper fractions (with or without π) → decimal numbers
•Irrational numbers (square roots, fractions made using square roots) → decimal numbers
Notes:
•In the following cases, calculation results may be displayed using r:
•Arithmetic operations and memory calculations
•Trigonometric calculations
• | In trigonometric calculations, |
| Entry value |

|
off the edges of the screen. You can see those parts by pressing lor r(depending on whether the left or right portion is hidden).
•Improper/proper fractions will be converted to and displayed as decimal numbers if the number of digits used in their expression is greater than nine. In the case of mixed fractions, the maximum number of displayable digits (including integers) is eight.
•If the number of digits in the denominator of a fractional result that uses π is greater than three, the result is
converted to and displayed as a decimal number.
The Line Editor
Entry and display
In the Line editor, you can enter and display equations line by line.
Notes:
•Up to three lines of text may be viewed on the screen at one time.
•If the length of the equation exceeds three lines, parts of it may be hidden from view after calculation. If you want to see the rest of the equation, press lor rto return to the editing screen.
•In the Line editor, calculation results are displayed in decimal form or line fraction notation if possible.
Editing the Equation
Just after obtaining an answer, pressing lbrings you to the end of the equation and pressing rbrings you to the beginning. Press l, r, u, or dto move the cursor. Press @lor @rto jump the cursor to the beginning or the end of the equation.
In the WriteView editor, you can use uand dto move the cursor up and
Back space and delete key
To delete a number or function, move the cursor to the right of it, then press N. You can also delete a number or function that the cursor is directly over by pressing @y.
The MATH Menu
Other functions may be available on this calculator besides those printed on the key pad. These functions are accessed using the MATH menu. The MATH menu has different contents for each mode.
Press Nto display the MATH menu. For example, in NORMAL mode, you can call the functions shown on the right.
Notes:
•When the 
or 
symbols are displayed, you can use uor dto display any hidden menu items.
•Ndoes not function when entering values or items in STAT, MATRIX, LIST, or EQUATION modes, or into solver functions or simulation calculations.
