About this Manual • Unless specifically stated, all sample operations in this manual assume that the calculator is in its initial default setup. Use the procedure under “Initializing the Calculator” to return the calculator to its initial default setup. • The contents of this manual are subject to change without notice. • The displays and illustrations (such as key markings) shown in this User’s Guide are for illustrative purposes only, and may differ somewhat from the actual items they represent.
Getting Started Before using the calculator, slide its hard case downwards to remove it, and then affix the hard case to the back of the calculator as shown in the illustration nearby. Turning Power On and Off Press to turn on the calculator. Press (OFF) to turn off the calculator. Note: The calculator also will turn off automatically after approximately 10 minutes of non-use. Press the key to turn the calculator back on.

Decimal Mark Dot ;ڏComma Specifies whether to display a dot or a comma for the calculation result decimal mark. A dot is always displayed during input. Note: When dot is selected as the decimal mark, the separator for multiple results is a comma (,). When comma is selected, the separator is a semicolon (;). Digit Separator On; Off ڏSpecifies whether or not a separator character should be used in calculation results.
1 Parenthetical expressions 2 Functions that have parentheses (sin(, log(, etc.
Note • When you press and obtain a calculation result, part of the expression you input may be cut off. If you need to view the entire input expression again, press and then use and to scroll the input expression. • Nesting of functions and parentheses is allowed. Further input will become impossible if you nest too many functions and/or parentheses. To undo operations (MathI/MathO or MathI/DecimalO only): To undo the last key operation, press (UNDO).
To obtain a decimal value calculation result while MathI/MathO or LineI/ LineO is selected Press (≈) instead of after inputting a calculation. Basic Calculations Fraction Calculations Note that the input method for fractions depends on the current Input/ Output setting on the setup menu.

*1 Input a variable as shown here: press and then press the key that corresponds to the desired variable name. *2 Pressing (RECALL) displays a screen that shows the values currently assigned to variables A, B, C, D, E, F, M, [, and \. On this screen, values are always displayed using the “Norm 1” Number Format. To close the screen without recalling a variable value, press . Independent Memory (M) You can add calculation results to or subtract results from independent memory.

• For information about how to scan a QR Code, refer to the user documentation of the QR Code reader you are using. If you experience difficulty scanning a QR Code: While the QR Code is displayed use and to adjust the display contrast of the QR Code. This contrast adjustment affects QR Code displays only. Important • Depending on the smart device and/or QR Code reader app being used, you may experience problems scanning the QR Code symbols produced by this calculator.
(displayed) or off (not displayed) using the Statistics setting on the setup menu. • Pressing the key while the Statistics Editor is on the screen will display a statistical calculation screen for performing calculations based on the input data. What you need to do to return to the Statistics Editor from the statistical calculation screen depends on the calculation type you selected. Press (Data) if you selected single-variable or (Data) if you selected paired-variable.

Important: Regression coefficient, correlation coefficient, and estimated value calculations can take considerable time when there are a large number of data items. Performing Normal Distribution Calculations While single-variable statistical calculation is selected, you can perform normal distribution calculation using the functions shown below from the menu that appears when you perform the following key operation: (Norm Dist).
Specifying the Number Mode of a Particular Input Value You can input a special command immediately following a value to specify the number mode of that value. The special commands are: d (decimal), h (hexadecimal), b (binary), and o (octal).
• To solve 2[2 + [ − 3 = 0, for example, press (Polynomial) in step 2. Use the Coefficient Editor that appears to input 213. • Pressing will clear all of the coefficients to zero. 4. After all the values are the way you want, press . • This will display a solution. Each press of will display another solution. Pressing while the final solution is displayed will return to the Coefficient Editor. • A message appears to let you know when there is no solution or when there are infinite solutions.
Constants: A constant is something whose value is fixed as soon as you finalize its input. A constant can be either a numeric value, or a calculation formula (such as 7+3, sin30, A1×2, etc.) that does not have an equal sign (=) in front of it. Formula: A formula that starts out with an equal sign (=), such as =A1×2, is executed as it is written. Note: Inputting a constant into a cell will take up 10 bytes of memory, regardless of the number of characters input.
where the formula is located. If the formula =A1+7 is originally located in cell B1, for example, copying and then pasting to cell C3 will result in =B3+7 being input into cell C3. Since the copy and paste operation moves the formula one column (B to C) and two rows (1 to 3) causes the A1 relative cell reference in the formula to change to B3.
Using Spreadsheet Mode Special Commands In the Spreadsheet Mode, the commands below can be used inside formulas or constants. These command are on the menu that appears when you press . Min( Returns the minimum of the values in a specified range of cells. Syntax: Min(start cell:end cell) Max( Returns the maximum of the values in a specified range of cells. Syntax: Max(start cell:end cell) Mean( Returns the mean of the values in a specified range of cells.
5. To apply the input, press . • This inputs =2A1–3 into cell B1, =2A2–3 into cell B2, and =2A3–3 into cell B3. To batch input the same constant into a series of cells Ex 5: Continuing from Ex 4, batch input into cells C1, C2, and C3 the values that are triple those of the cells to the left. 1. Move the cell cursor to cell C1. 2. Press (Fill Value). • This displays a Fill Value dialog box. 3. In the “Value” line, input the constant B1×3: (B)3. 4.
• The calculation you are performing has caused the capacity of the matrix or vector stack to be exceeded. ĺ Simplify the calculation expression so it does not exceed the capacity of the stack. ĺ Try splitting the calculation into two or more parts. Syntax ERROR • There is a problem with the format of the calculation you are performing. Argument ERROR • There is a problem with the argument of the calculation you are performing.
Replacing the Battery A low battery is indicated by a dim display, even if contrast is adjusted, or by failure of figures to appear on the display immediately after you turn on the calculator. If this happens, replace the battery with a new one. Important: Removing the battery will cause all of the calculator’s memory contents to be deleted. 1. Press (OFF) to turn off the calculator.
