Handling Precautions

Your calculator is made up of precision components. Never try to take it apart.

Avoid dropping your calculator and otherwise subjecting it to strong impact.

Do not store the calculator or leave it in areas exposed to high temperature or humidity, or large amounts of dust. When exposed to low temperature, the calculator may require more time to display results and may even fail to operate. Correct operation will resume once the calculator is brought back to normal temperature.

The display will go blank and keys will not operate during calculations. When you are operating the keyboard, be sure to watch the display to make sure that all your key operations are being performed correctly.

Never leave dead batteries in the battery compartment. They can leak and damage the unit.

Avoid using volatile liquids such as thinner or benzine to clean the unit. Wipe it with a soft cloth, or with a cloth that has been dipped in a solution of water and a neutral detergent and wring out.

In no event will the manufacturer and its suppliers be liable to you or any other person for any damages, expenses, lost profits, lost savings, or any other damages arising out of malfunction, repairs, or battery replacement. The user should prepare physical records of data to protect against such data loss.

Never dispose of batteries, the liquid crystal panel, or other components by burning them.

2 —

Before assuming malfunction of the unit, be sure to carefully reread this manual and ensure that the problem is not due to low battery power or operational error.

The contents of this manual are subject to change without notice.

No part of this manual may be reproduced in any form without the express written consent of the manufacturer.

Keep this manual on hand for future reference.

Note!

A mode guide is located above the display screen.

DEG, RAD, and GRA modes can be used in combination with the COMP and SD modes.

F9does not exit SD mode.

F0exits SD mode.

F0does not clear SCI or FIX specifications.

Always press t before entering DEG, RAD, and GRA modes.

Remember to always set the operating mode and angular unit (DEG, RAD, GRA) before starting your calculation.

Constant Calculations

Press +,,,-,or\twice after inputting a number to make that number a constant.

“K” is on the display while a constant is being used.

Use the COMP mode for constant calculations.

(2.3 3)

2.3 ++3=

(2.3 6)

kExponential Display Formats

This calculator can display up to 10 digits. Larger values are automatically displayed using exponential notation. In the case of decimal value, you can select between two formats that determine at what point exponential notation is used.

— 21 —

• NORM 1

With NORM 1, exponential notation is automatically used for integer values with more than 10 digits and decimal values with more than two decimal places.

• NORM 2

With NORM 2, exponential notation is automatically used for integer values with more than 10 digits and decimal values with more than nine decimal places.

To switch between NORM 1 and NORM 2

Press F9. There is no indication on the display of which format is currently in effect, but you can determine the setting by performing the following calculation.

1 \200=

5. –03

NORM 1 format

 

 

 

 

0.005

NORM 2 format

All of the examples in this manual show calculation results using the NORM 1 format.

kWhen you have a problem...

If calculation results are not what you expect or if an error occurs, perform the following steps.

1.F0(COMP mode)

2.F4(DEG mode)

3.F9(NORM mode)

4.Check the formula you are working with to confirm it is correct.

5.Enter the correct modes to perform the calculation and try again.

kMaking Corrections During Calculations

If you make a mistake when inputting a value (but did not yet press an arithmetic operator key), press k to clear the value and then input the correct one.

In a series of calculations, press kwhile an intermediate result is displayed to clear only the last calculation performed.

To change the operator key (+,,,-,\,A w,As, etc.) you just pressed, simply press the correct operator key. In this case, the operator of the last key you press is used, but the operation retains the order of precedence of the operation for the first key you pressed.

kOverflow or Error Check

The following conditions make further calculation impossible.

a.When a result (whether intermediate or final) or a total accumulated in memory is greater than ±9.999999999 1099.(“–E–”indicator appears on the display.)

b.When function calculations are performed using a value that exceeds the input range. (“–E–”indicator appears on the display.)

c.When an illogical operation (such as an attempt to calculate o andn whilen 0) is performed during statistical calculations.(“–E–”indicator appears on the display.)

d.When an illegal mathematical operation (such as division by zero) is performed. (“–E–”indicator appears on display.)

23 —

e.The total number of nested parentheses levels exceeds six, or when more than 18 pairs of parentheses are used. (“– 1–”indicator appears on the display.)

To clear any of the above conditions, press tand perform the calculation from the beginning.

In the case of condition e, you could also press k. This clears the intermediate result just prior to the overflow, so you can continue with the calculation from that point.

No error occurs when the result is within the range of(1 10 99) to (1 1099). Instead, the display shows all zeros.

kPower Supply

This calculator is powered by two AA-sizemanganese dry batteries (R6P(SUM-3)orUM-3).Replace batteries as soon as possible when display characters become dim and difficult to read.

Press tto turn power on.

Press ito turn power off.

Power automatically turns off (but data in memory is retained) if no key operation is performed for about six minutes.

Important!

Incorrect use of batteries can cause them to burst or leak, possible damaging the calculator.

Be sure to replace the batteries at least once every two years, regardless of how much the calculator is used. Old batteries may leak, causing serious damage to the interior of the calculator.

24 —

The batteries that come in the calculator when you purchase it are for testing only. They may not provide full service life.

All data stored in memory is lost when you replace the batteries. Be sure to write down important data before replacing the batteries.

Always be sure to load the batteries so their positive ( ) and negative ( ) ends are facing correctly.

Never mix batteries of different types.

Never mix new batteries with old ones.

Never try to charge batteries, take them apart, or allow them to become shorted. Keep batteries away from direct flame and heat.

Keep batteries out of the reach of small children. If swallowed, consult with your physician immediately.

To replace the batteries

1.Press ito turn power off.

2.Remove the screws that hold the back cover in place, and then remove the cover.

3.Remove the old batteries.

4.Install two new batteries with the positive ( ) and negative ( ) ends facing correctly.

5.Replace the back cover and secure it in place with the screws.

6.Press tto turn power on.

kOrder of Operations and Levels

Operations are performed in the following order of precedence.

1.Functions

2.xy,x1/y, R →P, P →R,nPr,nCr

3.,

4.,

Operations with the same precedence are performed from left to right, with operations enclosed in parentheses performed first. If parentheses are nested, the operaitons enclosed in the innermost set of parentheses are performed first.

Registers L1 through L6 store operations. There are six registers, so calculations up to six levels can be stored.

Each level can contain up to three open parentheses, so parentheses can be nested up to 18 times.

Example: The following operation uses 4 levels and 5 nested parentheses.

2 -OOO3 +4 -OO5 +4

The table below shows register contents following the above input.
