Page 5: Reading The Display
Reading the Display The display of the calculator shows expressions you input, calculation results, and various indicators. Input expression Indicators Math Math Math Math Calculation result • If a ' indicator appears on the right side of the calculation result, it means the displayed calculation result continues to the right. -
Page 6: Using Menus
Using Menus Some of the calculator’s operations are performed using menus. Pressing N or w, for example, will display a menu of applicable functions. The following are the operations you should use to navigate between menus. • You can select a menu item by pressing the number key that corresponds to the number to its left on the menu screen. - Page 7 6Fix 7Sci 8Norm Specifies the number of digits for display of a calculation result. Fix: The value you specify (from 0 to 9) controls the number of decimal places for displayed calculation results. Calculation results are rounded off to the specified digit before being displayed.

Page 8: Inputting Expressions And Values
Inputting Expressions and Values Basic Input Rules Calculations can be input in the same form as they are written. When you press = the priority sequence of the input calculation will be evaluated automatically and the result will appear on the display. 4 ×... - Page 9 Negative sign (–) Note: When squaring a negative value (such as –2), the value being squared must be enclosed in parentheses ( (- 2 )w =). Since has a higher priority than the negative sign, inputting - 2 w= would result in the squaring of 2 and then appending a negative sign to the result.

Page 10: Toggling Calculation Results
Math Math As shown above, the value or expression to the right of the cursor after 1Y(INS) are pressed becomes the argument of the function that is specified next. The range encompassed as the argument is everything up to the first open parenthesis to the right, if there is one, or everything up to the first function to the right (sin(30), log2(4), etc.) This capability can be used with the following functions: ', &, 1 6( "), 1l( $), 1i( %), !, 6, 1!( #), D. -

Important: • Depending on the type of calculation result that is on the display when you press the f key, the conversion process may take some time to perform. • With certain calculation results, pressing the f key will not convert the displayed value. -
Page 12: Using Engineering Notation
Degree, Minute, Second (Sexagesimal) Calculations Performing an addition or subtraction operation between sexagesimal values, or a multiplication or division operation between a sexagesimal value and a decimal value will cause the result to be displayed as a sexagesimal value. You also can convert between sexagesimal and decimal. The following is the input format for a sexagesimal value: {degrees} $ {minutes} $ {seconds} $. - Page 13 (Scrolls back.) f (Scrolls back again.) f Note: Calculation history data is all cleared whenever you press O, when you change to a different calculation mode, when you change the display format, or whenever you perform any reset operation. Replay While a calculation result is on the display, you can press d or e to edit the expression you used for the previous calculation.
