k Remove the insulation sheet!

Your calculator comes with a special insulation sheet, which isolates the battery from the

contacts in the battery compartment, to keep the battery from running down during storage

and shipment. Be sure to remove the insulation sheet before trying to use the calculator for

the  rst time.

To remove the insulation sheet

1. Pull the tab of the insulation sheet in the direction indicated by the arrow to remove it.

Safety Precautions

Be sure to read the following safety precautions before using this calculator. Be sure to keep

all user documentation handy for future reference.

Caution

This symbol is used to indicate information that can result in personal injury or material

damage if ignored.

Battery

• After removing the battery from the calculator, put it in a safe place where it will not

get into the hands of small children and accidentally swallowed.

• Keep batteries out of the reach of small children. If accidentally swallowed, consult

with a physician immediately.

• Never charge the battery, try to take the battery apart, or allow the battery to become

shorted. Never expose the battery to direct heat or dispose of it by incineration.

• Improperly using a battery can cause it to leak and damage nearby items, and can

create the risk of  re and personal injury.

• Always make sure that the battery’s positive k and negative l ends are facing

correctly when you load it into the calculator.

• Remove the battery if you do not plan to use the calculator for a long time.

• Use only the type of battery speci ed for this calculator in this manual.

Disposing of the Calculator

• Never dispose of the calculator by burning it. Doing so can cause certain components

to suddenly burst, creating the risk of  re and personal injury.

kTurning On the Calculator

Press o. This displays the same screen that was on the display when you last turned off

the calculator.

A Adjusting Display Contrast

If the  gures on the display become hard to read, try adjusting display contrast.

1. Press Nc3(SYSTEM) 1(Contrast).

• This displays the contrast adjustment screen.

2. Use

d and e to adjust display contrast.

3. After the setting is the way you want, press J.

Note

You can also use d and e to adjust contrast while the calculation mode menu that

appears when you press the N key is on the display.

A Turning Off the Calculator

Press 1o(OFF).

kKey Markings

MEMORY (Memory Management) 2(MEMORY)

SYSTEM (Contrast Adjustment, Reset) 3(SYSTEM)

• To exit the calculation mode menu without changing the calculation mode, press N.

kCalculator Setup

The calculator setup can be used to con gure input and output settings, calculation

parameters, and other settings. The setup can be con gured using setup screens, which

you access by pressing 1 N (SETUP). There are two setup screens, and you can use

f and c to navigate between them.

A Selecting the Display Format (MthIO, LineIO)

You can select either natural display (MthIO) or linear display (LineIO) for expressions you

input and for calculation results.

Natural Display (MthIO)

Natural display displays fraction, square root, derivative, integral, exponential, logarithmic,

and other mathematical expressions just as they are written. This format is applied both for

input expressions and for calculation results. When natural display is selected, the result of

a calculation is displayed using fraction, square root, or π

notation whenever possible.

For example, the calculation 1 ÷ 2 produces the result 1

2, while π

÷ 3 results in 1

3π

Linear Display (LineIO)

With linear display, expressions and functions are input and displayed using a special format

de ned by your calculator. For example, 1

2 would be input as 1 { 2, and log 24 would be

input as log(2,4).

When linear display is selected all calculation results, except for fractions, are displayed

using decimal values.

To select this display fomat: Perform this key operation:

Natural Display (MthIO) 1N 1(MthIO)

Linear Display (LineIO) 1N 2(LineIO)

Note

For information about the input procedures when using the natural display and linear

display, see “Inputting Calculation Expressions and Values” on page 14 of this manual and

the sections of this manual that explanation of each type of calculation.

E-13

A Specifying the Engineering Symbol Setting

This setting lets you turn engineering symbols on and off. For more information, see “Using

Engineering Symbols” on page 54.

To do this: Perform this key operation:

Tu rn engineering symbols on 1Nc3(ENG)1(EngOn)

Tu rn engineering symbols off 1Nc3(ENG)2(EngOff)

While engineering symbols are turned on (EngOn), engineering symbols are used when a

calculation result is outside of the range of 1 < x

 < 1000.

A Specifying the Complex Number Display Format

You can specify either rectangular coordinate format or polar coordinate format for complex

number calculation results.

To specify this complex number format

for display of calculation results: Perform this key operation:

Rectangular Coordinates 1Nc4(COMPLX)1(a+bi)

Polar Coordinates 1Nc4(COMPLX)2(r∠

Ƨ)

ENG conversion (page 53) is not possible while polar coordinate format is selected.

A Specifying the Statistical Frequency Setting

Use the key operations below to turn statistical frequency on or off during SD Mode and

REG Mode calculations (page 72).

To select this frequency setting: Perform this key operation:

Frequency On 1Nc5(STAT)

1(FreqOn)

Frequency Off 1Nc5(STAT)

2(FreqOff)

A Changing the BASE-N Mode Negative Value Setting

You can use the key operations below to enable or disable use of negative values in the

BASE-N Mode.

To specify this setting: Perform this key operation:

Negative values enabled 1Nc6(BASE-N)1(Signed)

Negative values disabled 1Nc6(BASE-N)2(Unsigned)

kClearing the Calculation Mode and Setup Settings

(Reset Setup)

Perform the following key operation to reset the calculation mode and setup settings.

Nc3(SYSTEM)2(Reset Setup)

E(Yes)

If you do not want to reset the calculator’s settings, press

J(No) in place of E

Note

If you include values or expressions in parentheses (

( and )) while using natural

display, the height of the parentheses will adjust automatically depending on whether they

enclose one line or two lines. Regardless of their height, opening and closing parentheses

take up one byte of memory each.

Inputting Calculation Expressions Using Natural Display

1. To input a speciﬁ c function, perform the operation in the “Key Operation” column of the

“Scientiﬁ c Functions that Support Natural Display” table.

2. At the input ﬁ elds indicated by



, input the required values and expressions.

• Use the cursor keys to move between the input ﬁ elds of the expression.

Example: To input 1 + 2

2 × 3

Specify fraction input:

Input the numerator:

1+2

Move the cursor to the denominator:

Input the denominator:

2*3

Execute the calculation:

Important!

• Certain types of expressions can cause the height of a calculation formula to be greater

than one display line. The maximum allowable height of a calculation formula is two

display screens (31 dots × 2). Further input will become impossible if the height of the

calculation you are inputting exceeds the allowable limit.

• Nesting of functions and parentheses is allowed. Further input will become impossible if

you nest too many functions and/or parentheses. If this happens, divide the calculation

into multiple parts and calculate each part separately.
