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 de-  
tergent 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.

• Before assuming malfunction of the unit, be sure to care-  
fully 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.

• 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.

Memory Calculations  
• Use the COMP mode for memory calculations.  
• Use Y, |, A { and Z for memory calculations.  
Y replaces current memory contents.  
• “M” appears when there is a value in memory.  
To clear memory, press 0 Y or t Y.

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 —  
load from Www.Somanuals.com. All Manuals Search And Down  
• 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.  
5. –03  
0.005  
1 \ 200 =  
NORM 1 format  
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 k while an intermediate  
result is displayed to clear only the last calculation per-  
formed.  
To change the operator key (+, ,, -, \, A w,  
A s, 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 impossi-  
ble.  
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 calcu-  
late o and n while n ҃ 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 dis-  
play.)  
— 23 —  
load from Www.Somanuals.com. All Manuals Search And Down  
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 t and per-  
form 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  
ѿ(1҂10Ҁ99) to Ҁ(1҂10Ҁ99). Instead, the display shows all  
zeros.  
kPower Supply  
This calculator is powered by two AA-size manganese dry  
batteries (R6P (SUM-3) or UM-3). Replace batteries as soon  
as possible when display characters become dim and difficult  
to read.  
• Press t to turn power on.  
• Press i to turn power off.  
• Power automatically turns off (but data in memory is re-  
tained) 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.

• The batteries that come in the calculator when you pur-  
chase 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 re-  
placing the batteries.  
• Always be sure to load the batteries so their positive (ѿ)  
and negative (Ҁ) 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

kOrder of Operations and Levels  
Operations are performed in the following order of prec-  
edence.  
1. Functions  
2. xy, x1/y, R P, P R, nPr, nCr  
3. ҂, Ȗ  
4. ѿ, Ҁ  
• Operations with the same precedence are performed from  
left to right, with operations enclosed in parentheses per-  
formed first. If parentheses are nested, the operaitons en-  
closed in the innermost set of parentheses are performed  
first.  
• Registers L1 through L6 store operations. There are six re-  
gisters, 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 - O O O 3 + 4 - O O 5 + 4  
The table below shows register contents following the  
above input.
