Using the protective case

Please do not slide the protective cose over the LCD.

1. Before use, slide the calculator out of the protective cose os shown below.

2. After use, slide the protective cose onto the calculator, os shown below.

Safety Precautions

Before using this calculator, please read the following safety precautions carefully. Keep this manual handy so that you can refer to it when needed.

Notice

This symbol indicates that there is a risk of injury or

damage if the specified safety precautions are ignored.

Battery

9 Keep battery out of the reach of children. If a

battery is swallowed, seek urgent medical advice.

• Do not charge, attempt to disassemble, short circuit, or apply heat to the battery.

9 When installing a new battery, orient it such

that the positive sign is facing upwards.

Use only the battery specified in this manual.

Disposing of the calculator

Do not dispose of this calculator in an incinerator.

It might explode and cause injury or fire.

The representations of the display and the keys in this manual are for explanatory purposes only and may not exactly match what you see on the calculator.

Other Precautions

Before using this calculator for the first time, press the H key.

The battery may lose some charge between the time the calculator leaves the factory and the time when it is purchased. Thus the original battery may not last as long as a new battery.

when battery power is very low, the calculator's memory may become corrupt or be lost completely. To avoid loss of important information, keep o copy of it elsewhere.

Avoid storing or using the calculator under extreme temperature conditions.

Low temperature will slow the calculator's response time, cause the display to appear incomplete, and shorten the life of the battery. In addition, the calculator should not be directly exposed to the sun or placed near a heater. High temperature may cause the casing to fade, distort the casing, or damage the internal circuitry.

Avoid storing or using the calculator in damp conditions or when there is high humidity or excessive dust. Doing so will damage the internal circuitry.

Do not drop the calculator or allow it to be subjected to extreme force.

Do not twist, bend or otherwise distort the calculator.

Note: Carrying the calculator in a pocket could

cause it to twist or bend. Do not use a pen or other pointed object to press

the calculator's keys. Use a soft dry cloth to clean the calculator.

Opening the case of calculator voids the warranty.

If the calculator is very dirty, a neutral household cleanser diluted in water can be used to clean it. Dip a cloth in the solution and wring it out before applying it to the calculator. Do not use benzine, o diluting agent or any other volatile solvent to clean the calculator. Doing so may damage the casing and the keys.

Two-Line Display

The calculator shows both the expression being calculated and the result of the calculation. These appear in a two-line display.

• The expression being calculated is shown on the upper line.

• The result is shown on the lower line.

If the result has more than three digits, a separator appears before each group of three digits.

Preparing to Use the Calculator

■ Modes

Choose the appropriate mode before performing a calculation.

this guide. Throughout this guide, the mode setting required

for each type of colculation is given when the calculation is explained.

Notes

To return the calculator to its default settings, as indicated below press[sm] ^ ^ (Mode) B

in that order. The default settings are: Calculation mode : COMP

Angle unit: Deg

Exponent display format: Norml Fraction display: ab/c Decimal point character: Dot

The mode indicator appears in the upper part of the display.

Before calculating, check the current mode

setting (COMP, REG or SD) and the angle unit

(Deg, Rad or Grad).

Input Limit

The memory of the calculator can accommodate

79 steps in any one calculation. When you press

a number key or an arithmetic operator key (D , B,D,B ). it occupies one step. Pressing HorH does not occupy a step. So pressing [Hi] [^ , for example, takes up only one step.

When you input the 73"^ step of any calculation, the cursor chonges from " to the fact that the capacity of the memory is almost used up. If what you want to input contains

more than 79 steps, separate the calculation into

two or more smaller calculations and then combine them os you go.

Press S to recall the previous result, which can

then be used in the next calculation. Please see the section on Key Memory for more information about the S key.

Error Correction when Entering

Press H or E to move the cursor to the position needed.

Press H to delete the digit or function at the position of the cursor.

Press the H ® keys to activate the insertion

cursor []. Whatever you insert now will appear at the cursor's current position.

Press the [wi] [¡ns] key to return the cursor to its normal

functioning.

Recalling a Previous Calculation

Each calculation and its result is kept in memory. Press H to recall the previous calculation and its results. Press the S key again to recall the next previous calculation, and so on.

When a previous calculation is recalled, you can activate editing mode by pressing^ orQ.

After any calculation, the calculation con be edited by pressing g or immediately.

Pressing does not clear the calculation memory. Therefore, when you press ® again,

the previous calculations are still available. The capacity of the calculation memory to store

expressions and calculation results is 128 bytes. The calculation memory is cleared if the:

■ [pg key is pressed

- H C^(or^) Hare pressed (which initializes the calculator)

- calculation mode is changed

- power supply is turned off

■ Error Indicator

• If an error occurs, press ^ or . The calculation reappears and the cursor is located where the error is.

■ Multi-statement

A multi-statement is an expression consisting of two or more smaller expressions. The expressions are separated by a colon (:)

■ Exponent Display Format

The calculator can display up to 10 digits. Values needing more than 10 digits will automatically be displayed in exponent notation. Two exponent formats are available.

• To change the display format, press H repeatedly

until the appropriate settings screen appears.

Fix

For an exponent setting, press . In the settings screen that appears, press CD to choose Norm 1 or El] to choose Norm 2.

Norm 1 Exponent notation is applied automatically to any

number whase absolute value is greater than ar equal to 10'° or less than 10 °.

Norm 2 Exponent notation is applied automatically to

any number whose absolute value is greater than or equal to 10'° or less than 10 ’.

In this manual, results are expressed in Norm 1 format.

■ Decimal Point and Separator

The display setting (Disp) screen is used to specify the required decimal mark and the character to use before groups of three digits.

To change these settings, press [j the settings screen appears.

Press CD H to display the settings screen. Press the number key ( CD or ED ) corresponding

to the setting you want:

ED (Dot) : Decimal point and comma separator

ED (Comma): Decimal comma and point separator

Initializing the Calculator

To initialize the calculator (which clears the memory and all variables, and resets all modes to their default settings) press: [wi] ED (ALL) B

Basic Calculations

■ Arithmetic Operations

To perform a basic calculation, select COMP mode

by pressing g .

COMP...................................................................................H DE

When raising negative values to powers, make sure that the negative sign is inside the parentheses around the value. Please see the section on Sequence of Operations (page 33) for more information.
